I do not expect the content to be the same with 2008.CSCEC - Mechanical 10:33:18I got a note in chinese said that ASHRAE update its whole version every four years, that why I think maybe in the previous version the main content should be the same.beki 10:36:46I have checked now, as I have two versions 4 year difference I compare 2009 with 2005......

CSCEC - Mechanical 13:29:56The Little House series is based on decades-old memories of Laura Ingalls Wilder's childhood in the Midwest region of the United States during the late 19th century. The best-known of the books is Little House on the Prairie. The books are told in the third person, with Laura Ingalls acting as the central character and protagonist, and are generally classified as historical fiction rather than as autobiography, although several of the later books are almost purely autobiographical. Wilder's daughter, author and political theorist Rose Wilder Lane, assisted her mother with the editing of the works. The depth of her involvement, and the extent of her influence on the theme and content of the books, has been the subject of some debate in recent years, but almost all Wilder scholars and her biographers consider that the writing of the books was a tense but ultimately effective continuing collaboration between mother and daughter — Wilder writing the books, Lane editing them.

beki 12:59:44All OK?CSCEC - Mechanical 13:02:04Yes, I am prepareing the letter to GMF, made a slight modification on item 2beki 13:01:51Good; Are also preparing an 'off the record message for Raymond?CSCEC - Mechanical 13:03:49yes, Mr. BAI will arrange the meeting timebeki 13:06:28I think that one strong point could be made out of the fact that the cooling capacity of 509kW in the so called 'executive summary' can easily be proven incorrect for 31.5 @ 81% RH by someone who has access to the psychrometric chartCSCEC - Mechanical 13:09:10I agree. I have a questine about item 5‘If with an ambient temperature (read ON-COIL condition) of around 17 Degr. C the sensible cooling load is calculated as 320 kW, then we really wonder how you will get the 2.1 DegrC below zero necessary to achieve this with an airflow of 13.53 m3/s"


beki 13:10:28If the On Coil condition is 17 Degrees (outdoor temperature) and the applied capacity is 320 kW, then the air should comout of the coil at this low temperature.

CSCEC - Mechanical 13:13:53he must argure it is the internal building load, the building load = plant load, there is no coil load in his reportbeki 13:14:48That is why I tell him not to answer this... If he says building load..... then he should explain where the high latent load is coming from at peak load,this should then represent ....... number of peoplebeki 13:17:058000 people (at 70W latent) will give a latent building load of 586 kWbeki 13:17:56

CSCEC - Mechanical 13:24:15I think item 5 can be argued.in case 1245people in the area,1245x120=149400wlighting 20x5000=100000wequipment 5x5000=25000w,together will be 274kwCSCEC - Mechanical 13:25:19my point is it is possible figure for internal loadbeki 13:24:59No, The point is that the load CANNOT represent building load. Because if it is building load than the Latent Load can be proven wrong.beki 13:27:11For the calculation to be correct, the whole of the table should make sense. It can be shown that the tabel as a whole is wrong.CSCEC - Mechanical 13:33:14I think it is more clear to point out the latent load is impossible as you analysed than to argue the plant load should be coil load should not equal to building load . I will make a mo

dification,and send to you to check if you are not tooo tiredbeki 13:33:12

Success to send file "CHILLER_SEQUENCE_r3.zip"(36.00KB).

beki 15:08:45Dear Mr. Bai,

Following the issued variation for new lounges on level 2, CSCEC had requested a comfort analysis using CFD calculation method in order to see if the proposed method of air conditioning would give satisfactory results.

The issued variation was based on the use of displacement ventilation with 100% fresh air.

Because of the climatic conditions in Mauritius the air that will be supplied in this manne

r to the areas will have a high humidity content.This will result in having quite high Relative Humidity, which exceeds the recommended values for comfort.

The results of the CFD calculation show an expected range of Relative Humidity from 62 to 82%

While outdoor weather condition may be quite pleasant even with high relative humidity, the conditions indoors are experienced differently.Indoors there is no ‘breeze’ and the temperature is artificially lowered without taking sufficient amount of moisture out of the air to provide a suitable ‘room condition’

As this may well lead to complaints, I think it is important that CSCEC informs the Engineer of the predicted results of high relative humidity, so that the design consultant can judge whether this is in line with its design intent or not, and take the necessary measures in case the results are not acceptable.

As the CFD calculation was done as part of the works related to the issued variation, there is a valid reason to submit these calculations.If CSCEC does not inform the design consultant, the company must accept all responsibility for any future complaint.

I therefore strongly recommend you to send the CFD calculations to the Engineer.

Regards,..................PS this has also be sent using QQmailCSCEC - Mechanical 15:47:04I have not seen Bai this afternoon, he told me Remond would come this afternoon.beki 15:50:47You still have time (are you counting days, hours or minutes?)CSCEC - Mechanical 15:51:25No, I have not.

CSCEC - Mechanical 16:42:22in secondary circuit do we need flow switch or flow sensor?CSCEC - Mechanical 16:42:38


beki 16:49:161. There is no need for a flow switch.2. A flow sensor can be used to measure the cooling capacity if also the supply and return temperatures are known.3. The supply temperatature is common and can be measured as indicated on the chiller plant schematic that I sent.4. The flow can be measured with an expensive MAGFLOW unit, or witha relative cheap PADDLE WHEEL device.If there is no specific spec for it then I should go for the wheel.

So what you need at first is the amount of expected condensate that will flow out of the units.beki 10:03:06That you calculate with the flow-rate of air in kg/s and the reduction in moisture content given as g/kg.beki 10:16:49About condensate drainage there are no specific regulations related to the sizing in Ashrae. what you can find is topics related to condensate from steam installations, but that is not applicable, the other reference just mentiones an issue related to coils that have been iced up, and that you must take care that the condensate (when it melts) can flow freely away.beki 10:16:59Condensate Drains. When coils defrost, condensate that hasformed as ice or frost on the coils melts. This new condensatecollects in a pan beneath the coil and flows into collection drainsoutside of the freezer space. Because the space is cold, condensatepans are connected to the hot-gas defrost system or otherwise heatedto prevent ice formation. Likewise, all condensate drain lines mustbe wrapped in heat-tracing tape and trapped outside of the refrigeratedspace to ensure that condensate can drain unrestricted.

beki 10:18:38Now I will see in the drainage sections that are part of the plumbing (not HVAC, -> not ASHRAE)beki 10:26:47So back to ASHRAE:beki 10:27:14Table 21 Vented Dry Condensate Return for Gravity FlowBased on Manning Equation

beki 10:43:58Usually the slope of the pipe should be in the order of 0.5 to 1.0 percent in case you have a long run be careful for the total height difference. You can continue to go vertical as in normal drains.beki 10:49:15There are two return methods described. One that is DRY and one that is WET. The DRY one refers to a pipe that is not full with water, the WET one is a pipe full with water. (different table for sizing).

Some rooms need over pressure (lounges) and some need underpressure (Kichen, toilet etc.) the level of difference should not be large, only in the order of 10 Pascal.beki 13:30:54Ther building as a whole needs over pressure so that the warm and moist air does not enter. I would say that about 10 Pa over-pressure would do, but of course that also depends a bit on the wind. The pressure caused by the wind is in the order of 0.5 * velocity pressure = 0.5 x 0.6 * v2 PaCSCEC - Mechanical 13:30:20

They seem to have an inexhaustible energy to spit rubbish..CSCEC - Mechanical 14:10:25Let them take this to arbitrationbeki 14:12:22You will win the case. By the way, you see that the wetbulb has been reselected to 27.3 (= 72.5% RH).CSCEC - Mechanical 14:13:12haha,they made story so casuallybeki 14:20:33The poor man, he seems completely mislead. When you put 31.5 at 72.5% RH through a coil of 509 kW then the off coil cannot be less then 18.8 DegrC and the RH in the bulding cannot be less than 72.6% ( that is without people load). The max sensible cooliong is 84 kW and that should also include the fan and duct losses.beki 14:26:19This morning I had the following idear; Why not involve Hevacomp in a comment on the submitted calculation results. According to us these results are not possible, and show total incoherence between each other. If Hevacomp can agree that this result cannot be correct then story is finished.CSCEC - Mechanical 14:27:56Good idear. But do you think Hevacomp may deal with this?beki 14:29:43The shall not have to take any responsibility for the results, their only task would be to explain to us how to interpret these results.

Date:05-01-2012beki 14:40:29they made story so casually, as you so well spoken say, that a new outdoor condition has been created. Although referring to ASHRAE, the Plaisance data do not list the combination 31.5 @ 27.3, the 27.3 wetbulb is listed in combination with a mean coinciding DryBulb of 30.0, and not 31.5beki 16:15:34Hi, time is passing.. are you alright?CSCEC - Mechanical 16:14:44[Auto reply]您好，我现在有事不在，一会再和您联系。CSCEC - Mechanical 16:51:59I just finished a class about control sequence to my coleaguesbeki 16:53:22So how is it to be teacher?CSCEC - Mechanical 16:52:55

beki 08:06:58Yes that is better, Flow sensors in the supply and temperature sensors in the return. In the

house now with chocolat as breakfast and and a variety of wishesCSCEC - Mechanical 08:08:03I THINK THE TEMP SENSORS ON EVERY SECONDARY SUPPLY PIPE IS NOT NECESSARY,BECAUSE THERE ARE TEMP SENSOR ON THE MAIN HEADER (IN THE SCHEMATIC DRAWING YOU MADE IS T2)CSCEC - Mechanical 08:08:32


beki 08:13:45

You understand well.On the diagram that I made the common supply is measured, and the common return as well.But for the individual returns you can measure the temperature in order to display the energy consumption per circuit.This is to be done in combination with the flow sensor.However, it would be better to put also the flow sensor in the return because the temperature of the return is higher, and so you have less trouble with the condensation.

beki 08:19:09I just forward you on QQmail a messager received from Halton.CSCEC - Mechanical 10:03:23questine：why you perfer to put the blowdown downstream of the inlet valve？CSCEC - Mechanical 10:06:43Youhave mentioned it is easy to control, can you give me more explanation?beki 10:07:21Believe it or not, but I was just thinking about you being so busy... The blowdow valve should be anywhere after the motorised inlet valve, but - andgthat is important - at a location that can easily be reached. That means that you maybe have to make a take-off (T) from the inlet pipe (after the motorised valve) and route this pipe (not so big in dia) to a location that is accessible.beki 10:09:56It is easy to control....... what exactly is IT ? The adjustment for the blowdown rate should be done using measurements made on the concentration of dissolved solids. Or is it something else that you meant?CSCEC - Mechanical 10:10:07Can it be anywhere along the circuit, or must after the inlet valve on the supply water pipe for colling tower?beki 10:12:34It is essential that it is after the inlet valve in order for it to be very simple. If you want you can put it before (but in the pipe that leads to that cooling tower, not to another or common) and then put a solenoid valve that needs to be activated when the cooling tower inlet valve is open.beki 10:16:42Now I am thinking about it, I may not be completely right.beki 10:16:52(or totally wrong)CSCEC - Mechanical 10:17:12Ypu mean the valve is in open position so when the motorise inlet valve open,it will drain down water.CSCEC - Mechanical 10:17:31ypu==youbeki 10:20:30Tje idea of having it after the inlet valve was to make it simple, because the flowrate of drained water is then automatically controlled by the number of cooling towers in operation and remains a percentage of the condensate flow.

beki 10:22:38If you do it anywhere else, then you need solenoid valves to control the quantity, (or maybe one modulating valve that is controlled in steps depending on the number of pumps in operation)beki 10:24:25You==LuCSCEC - Mechanical 10:24:29

By the way, Have you already contacted CSCEC in MauritiusCSCEC - Mechanical 08:58:01I read letter 143 from GMF,they uesd a new idea RUN-AROUND COIL.I check it on web, it is a heat exchange system, will use water to take energy from exhaust air and translater to supply air.beki 09:00:16Yes I have relied to that letter, you were in copy. The idea will reduce the relative humidity, but at the same time increase the load. I have not seen any further details. Have you read read my letter to Mr. Bai saying that GMF tries to fool them by speaking about HALTON?CSCEC - Mechanical 09:05:50Although it is possible to save energy, the plan need to add equipment and to redesign the exhaust air system.This is not concept design period, so no matter what kind of solution could solve the problem, it is impossble to change.beki 09:06:13

A dutch say: Geduld is een schone zaak, meaning: PatienceCSCEC - Mechanical 09:06:09I read you reply.CSCEC - Mechanical 09:06:39

beki 09:09:20There is no energy saving when using a runaround coil that processes high level exhaust. The temperature difference between inlet air and exhaust air is verly little, so you cannot use it to 'pre-cool' the air. If used after the cooling coil it will reheat the air, but that is the same as increasing the fan and duct losses, it will just force the off coil temperature down, ... and I miss you too.CSCEC - Mechanical 09:10:59Mr Bai ask me to reply the letter,I will write the letter and send it to you first.I am not sure when I can finish itbeki 09:12:42It is now14:10 at your place, here it is just ten past eight in the morning. Do you think you might have if by the end of your work day, or are you already nearly to leave the office?CSCEC - Mechanical 09:13:01Do you have any reference about run-around coil? send it to me pleasebeki 09:16:57I have worded with in on one porject and I have done the comissioning of it. I will find you some info, but in principle it is very simple. You place a coil in the exhaust stream (' Add the pressure drop of this coil to the fan !!!!!) , then you use a circulating pump to get the water trhough it and guide the waterthrough anoither coil that is addionally place near or in the airhancler (Add the pressure drop to the total static pressure !!!!) .beki 09:18:24Have you seen the details of what they proposed, because, although the letter mentioned it was enclosed, I did not receive any such enclosure or other details from this proposed solution.CSCEC - Mechanical 09:19:05I have not.CSCEC - Mechanical 09:19:38I will ask MR bai nowbeki 09:19:44If Mr. Bai asks you to comment on it, then, to be sure what they meant,beki 09:19:52OK you got itCSCEC - Mechanical 09:42:06GMF sent a hand copy of calculation to CSCEC,they are scanning it and will send it to mebeki 09:43:25Ok, I will be interested to see that also...

CSCEC - Mechanical 09:56:30the exhaust air temperature is 24,what kind of water should be used? untreated water？ ordinary temperature？beki 09:56:49I just sent you some references that mention run-around coils. I will see if I can get hold of ome calculation method to find the efficiency. But as I said earlier, if used for de-humidification (placed after the cooling coil) then it will increase the required cooling capacity for 100% fresh air airhandlers. It will need about 5 times more cooling poser than the power that is transferred from exhaust to supply air.beki 09:56:55Hold on....CSCEC - Mechanical 09:59:48I will leave for ten minutes,then I will backbeki 10:00:03The water is running around between two coils. One place in the exhast air stream and the other in or near the AHU. It is a closed circuit that needs to be filled with the same kind of water as the chilled water system. There should be an expansion vessel to absorb the volume change of the water when the temperature varies. there should be a strainer and one (or if redundancy is required two) circulating pump. The make-up can be directly form the chiled water.beki 10:00:10OK I will wait.9:22:51

will have plenty of questine for youbeki 10:51:26Make the questions many and un-solvable from far, so that 'they' will ask me to come. That I would like the best.CSCEC - Mechanical 10:56:45I KNOW

Date:02-03-2012CSCEC - Mechanical 10:57:22HOW ARE YOU THESE DAYS?beki 10:58:50I am very busy with my work, I travel a lot. But that is not all.beki 11:00:18I am often thinking about 'mauritius'. and if you have seen my mails, you might understand. Did you check QQmail already.CSCEC - Mechanical 11:17:12I checked the mail quickly，in China we can not get on youtube.beki 11:20:56I can send you by qq, the files are not so big. But I think that I also enclosed the files in the email. Did you get: Biblos_Sea.mp4 (7MB) ? and Lu in the woods.mp4 (10MB) , these are the ones that I put also on youtybe.CSCEC - Mechanical 11:23:57I am really in the mist recently, I think you may not understand how complicated the situation is.CSCEC - Mechanical 11:29:21Try to be simple and happy.beki 11:48:39To be in the mist... I could probably understand quite well, but with so little information from your side it is of course a lot of guessing. I really whished that you could share this more with me. We have been able to understand each other quite well and I think that this

deserves some dialogue. And about the simple happiness. Its alright with me. I am actually quite happy, and feel rich with the thoughts, feelings and emotions that I can have. Simple is maybe not always the right word to describe me, but simple happiness, yes that could do often. When you will be in mauritius you can read the book that I send you. It has been so much of a joy for me to read it, that I would like you to red it too,.. the same boo

k that I bought here in Beirut.CSCEC - Mechanical 11:53:45

Thank you, my professor.I know I am a quite lucky personbeki 12:00:44The book is not so much from me as a professor, athough I like that role a lot, especially with students like you, ultimate joy. I wish though that I could teach (or convince) you to be more open with me. Even in the mist, thick mist like I once experinece as a child, whereby it was hard to see my own shoes, even under those circumstances, when beign close enough.. things can be safely shown.beki 12:01:53

CSCEC - Mechanical 12:10:41I found it quite difficult to concentrate on something at home. I can not be quiet in my heart.beki 12:22:56I really hope Lu that thing will clear up, I hope this for you as well as for myself. For now, probably best to just relax and wait for wisdom to come with it's answers. But for whatever will bring this, I really want us to meet and speak, that's such a strong wish..CSCEC - Mechanical 12:22:58Thinking too much make me feel tired and useless, I try to be simple and happy,hope I have the wisdomCSCEC - Mechanical 12:28:51I will get down.beki 12:29:29English please, this means you will be leaving now?CSCEC - Mechanical 12:30:23

I think I am speaking English.Do you know how much glue in my brain?beki 12:31:50What I do know, is that you used some of that glue to stick me to you.CSCEC - Mechanical 12:34:06

See you thenbeki 12:35:09Absolutely.. And don't worry about not feeling useful, your time will come , your wish is too strong ..

So you will finally pack your suitcase.Have you ever done something with the report that I made in reply to the run-around coils from GMF?

CSCEC - Mechanical 10:02:31No, I have not finished anything, I will be when I am backbeki 10:04:35I am curious to know whatever happened with that story, and how they may have penetrated back into the system? did you get any information about that?CSCEC - Mechanical 10:05:53They will not penetrate backbeki 10:07:44

I am a bit shy to ask, but did you get my message about->


I got your messagebeki 10:35:15

I guess you are very busy now.Once you are back in Mauritius, you will have surely some more time and opportunities to ask maybe even 1000000000000000 questions, which I shall of course be most willing to answer.I look forward to a bit more conversation.

12:29:56The contact canceled sending "run around coil.psy". 0KB of 1.00KB has been received successfully.

CSCEC - Mechanical 13:28:57According to DEHUMIDIFICATION ENHANCEMENTS FOR 100 OERCENT OUTSIDE AIR AHUS (annex of GMF letter), run around coils are two coils with a small closed loop piping system. One coil is precooling coil, it locates upstream from the main coil, it absorb heat from the air. Another coil is reheating coil, it locates downstream from the main coil, it give back the heat get from the precooling coil to the air. The two coils function is quite like heat-exchanger. After the precooling coil, the main coil can treat the air into lower temperature with the same cooling capacity, so make the air drier. Reheating coil will heat the air using the enthalpy get from the air.It is really a good idea to save reheat energy.12:30:41

beki 13:34:47by mail pleaseCSCEC - Mechanical 13:33:54okCSCEC - Mechanical 13:36:15I try to make analysis but can not be sure it is right or wrong. If the run coil has the function what the water temperature different in the coil ?beki 13:39:10one moment please..beki 13:42:23Had to have discussion with our employees.. timesharing with you.CSCEC - Mechanical 13:41:57

I have time and patiencebeki 13:50:29OK, lets start. First, how many coils do you consider, and where are these located. In your brief description I see two run-around coils and one AHU main cooling coil. One run-around coil before the AHU cooling coil and one run-around coil after the AHU cooling coil. Do I understand correctly what you have described?CSCEC - Mechanical 13:50:00YESbeki 13:52:05Well then, I will check now your psy chart (one moment please, checking mail now)CSCEC - Mechanical 13:51:15I will send you GMF letterbeki 13:52:29OKCSCEC - Mechanical 14:06:25Please read page 53 coil loop run aroud precooling, reheatingCSCEC - Mechanical 14:06:49Email is on the way....beki 14:08:09Ok, I will download the mail, but I have already a first assesment:CSCEC - Mechanical 14:08:00The second mail is from GMF'S letterbeki 14:10:20The first think is to mention that you cannot save energy with the configuration that you describe, as you only replace the energy from before to after the coil. Saving would have b

een to use the colder air that you throuw out of the building to precool the incoming air.beki 14:11:44The second thing is that you should make the energy tranfer in the two run-around coils the same. otherwise the universe will ex- or implode after a while. Energy in our world is always conserved.beki 14:14:11By making these two figures the same (upstream coil takes up heat and the downstream coil gives out the heat) then they should show the same temperature change between in and out because the airflow rate is the same.CSCEC - Mechanical 14:14:23Have you got the second mail?beki 14:17:08Thus if you have the upstream coil cooling the air down from 31.5 to 27, then the downstream coil will inctrease the temerature from 14.9 to 19.4 or somewhere there.beki 14:17:18I will now check the second email..beki 14:18:19download in progress (2.5 MB)CSCEC - Mechanical 14:17:08There has an analysis on the psychart, I can not understandbeki 14:18:52Do you understand the comments I make on the chart that you issued?CSCEC - Mechanical 14:18:32Yes, clear.Although there are so much glue in my brainCSCEC - Mechanical 14:18:36

beki 14:20:09I would love to have a look in your brainbeki 14:21:05I will look for a brain-glue dissolverbeki 14:23:36In fact. Brain Glue does seem to exist !!http://www.nytimes.com/1982/11/23/science/brain-s-glue-discovered.html?pagewanted=all

Date:13-03-2012CSCEC - Mechanical 14:22:53e air down from 31.5 to 27, then the downstream coil will inctrease the temerature from 14.9 to 19.4 or somewhere there.Is that mean this coil loop run around precooling and reheating coil can not work,or some of my setpoit are wrong?

beki 14:26:21You could have a smaller coil that transfers a bit less energy from the upstream to the downstream part of the coil, but that will of course also reduce the improvement of dehumidification while keeping the AHU cooling coil working at the same rate.

beki 14:30:29Further it should be mentioned that the capacity of the cooling coil to a large extend depends on the ON-COIL temperature. By reducing this temperature, the coil will have a lower cooling capacity.CSCEC - Mechanical 14:37:06Waiting for your comment about the analysis in the article...beki 14:38:25I have downloaded and read the run-around coil description. They make a bit toom much advertisement for it,beki 14:42:12The idea is to use replace the energy from before to after the coil using the run-around coils, and thereby alowing the AHU cooling coil to concentrate more on the de-humidification. (to speak in metaphoric way). In theory this works, but you must see the actual figures before deciding if this can be used.CSCEC - Mechanical 14:41:36As you mentioned the capacity of the cooling coil to a large extend depends on the ON-COIL temperature, how to decide the difference coil capacity?CSCEC - Mechanical 14:42:29In theory this works, but you must see the actual figures before deciding if this can be used.----That is what I want to know

beki 14:45:41I have a program from Technisolve (makers of psychart) that can simulate coils. I think you have this prgram also. Check and if you want I can send it. (it is called CWC.exe). I will now make a check using the psy chart data you you gave me just now.CSCEC - Mechanical 14:46:36I have that programme, I will try it.beki 14:56:55A hint in using the CWC.exe program: After you give the data in you should press the calculator button (icon position 4th from the left) and then the View icon, which show the report. You can then copy the report (second option from the left on the report window, and then you can use 'Paste' in excel. So you must have an empty worksheet open, make it the active window by clicking on it and then do Ctrl+V or right-click and 'Paste'beki 14:58:38Unfortunately I must now attend a Video Conference from 16:00 hours your time. I think

it might tak an hour. I will be back after it.CSCEC - Mechanical 14:58:51OK, I will say hello to Roshan,Safdar is on vacationCSCEC - Mechanical 16:42:44I will be back after dinnerbeki 16:44:28I am away now. I will contact you later.CSCEC - Mechanical 18:44:42

So I will postpone that till tomorrow, hoping that they leave me here alone a bit more then today. Did you start reading the book?CSCEC - Mechanical 19:26:39Yes, several pagesbeki 19:29:02Do you like it?CSCEC - Mechanical 19:30:21Can say it now. I think I need to read more, but it is somthing I have interest to know.If it is in CHINESE I will finish it soonbeki 19:36:08OK, take your time. I was quite facinated by the style he is using. Using such short sentences but saying so much. Anyway, I am leaving now and will come back tomorrow. I find

it so nice that I can talk to you again. Bey BeyCSCEC - Mechanical 19:34:12


morning.The psychart and the report do not match.Please check.6:52:07

Failed to transfer "run around coilrrr.psy". Unknown error occurred.

CSCEC - Mechanical 07:54:41hi. I do not kown what happened, I psychart is correct.beki 07:54:50Good morning, Please send file by mail, because it seems not possible to doit the quick way. I will check if I have sent the right combination. But bottom line of the story is that: If you want to dehumidify, however you do it, it comes at a price.beki 07:58:03Additional dehumidification can be done by using part of the cooling capacity and transform the 'sensible' cooling into 'latent' cooling which happens when you use run-arounnd coils as shown, or you frce the coil to do more latent cooling by adding more heat into the system (electric coil).

beki 08:03:08

Do you need more explanation ?CSCEC - Mechanical 08:06:05No, I am clear now.beki 08:06:46Have you been asked to prepare a reply to the letter of GMF that proposes this metod?CSCEC - Mechanical 08:16:02No, they replyed a letter but not metioned anything about this.CSCEC - Mechanical 08:17:29I think most of the letter were written by you .You may check it on aconex CSCEC-LETTER-100231beki 08:18:24OK, I will check What happend with GMF and their mechanical subcontract? And.. did you sleep well?CSCEC - Mechanical 08:19:50Not so well, why you ask? You can feel it?beki 08:20:05As if you were herebeki 08:27:38I just read the letter,which is indeed my reply given to CSCEC. The next letter that I prepared, talking about their proposal for run-around coils was only sent to you while you were in Jinan. This was in reply to a follow up letter from GMF, the one with encloseures. Actually I misunderstood at that time their suggestion, as thery were speaking about saving energy. That cannot be accomplished with the confiuration that we have been talking abount now, but only with a system that uses the extract to precool the inlet air.beki 08:28:20Anyway, you have been thinking so much about run-around coils. Are you going to do something with it?CSCEC - Mechanical 08:33:46I will ask more information from the supplier about it. Now I try to finish niose calculation.beki 08:34:27oK, if you want, let me HEAR about it.CSCEC - Mechanical 08:45:56I willbeki 08:47:05You give me the feeling that you are more close to crying then laughing. I wish I could cheer you up.CSCEC - Mechanical 09:26:00I am trying to be nomal. It need time. Do not worry, may be I am this kind of person, not stable.

CSCEC - Mechanical 12:27:52The situation of noise calculation is like this, when MR PU did the calculation he found useing the silencer we choose before can not reduce so much niose in some system. So firs

t he try to change to other kind of silencer but found that pressure drop on the silencer is much higher than last one.beki 12:34:35The situation that you describe does not show me a conclusion.beki 12:35:28It is important to include the number of fans that are in the hall, used for the general roof extract.CSCEC - Mechanical 12:34:43That mean we need higher pressure loss of the fan. But AHU has been orderdbeki 12:36:03Ok, do not panicbeki 12:36:35The pressure drop should be see in relation to the total pressure drop for which the fan has been designedbeki 12:37:34In general this was quite high as I rememberbeki 12:38:46So I suggest you look at the fan curve (should be somewhere available), and add the extra silencer requirement to it.CSCEC - Mechanical 12:38:35I know,but what we choose before is a quite simple silencer the pressure loss is not more than 15pa,if we use now silencer it will be over 100pabeki 12:40:08This 100 Pa is still small in relation to the total pressure drop of the fan (I conveniently hope)CSCEC - Mechanical 12:44:27First of all, I am not sure if the calculation is right or wrong.beki 12:45:36That is a good startCSCEC - Mechanical 12:45:11You feel I am back?beki 12:46:22Absolutely.beki 12:46:53I want to be back too!!CSCEC - Mechanical 12:48:20I want to make it clear myself only. My company can not tolerate any change or daley.No timebeki 13:01:12If you cannot afford any change, then you just have to hope for the best. As I said, for the AHUs it may not be too bad, as in general the fan total pressure is quite high. But be careful with the extract fans !!!!!!

I think you can feel itbeki 08:34:43This answer is indeed one that identifies you.beki 08:35:17Did you try to send another psy-chart?CSCEC - Mechanical 08:37:09The one I mentioed that not match with your report?beki 08:38:08I do not know, when I connected this morning (after the internet was back on line) I received a request to accept a psy-file. But I was thinking that you had started Noise Calculations so I was surprised.CSCEC - Mechanical 08:39:49No, I did not send it.beki 08:43:07Well, then it must have been floating around, lost in space and finally landed. By the way my screen still says Non-local Sign-in although yesterday there was not such description. Maybe CSCEC changed something related to their internet connection.beki 08:43:50

If I really need help I will call youbeki 08:49:32Ok, if someday in the future you wish to borrow money, I will ask you to come and colle

ct personallybeki 10:29:52Everything according to plan?CSCEC - Mechanical 10:34:00I had a meeting in ADPI office.beki 10:35:49I spoke with Dominique, but not related to Mauritius. Although he mentioned that he is still busy with it. I did not want to get involved throught him.CSCEC - Mechanical 10:36:53Before I came back, Mr PU has finished the first version of niose calcularion using the ex

cel sheet you gave me. Roshed send it to ParisCSCEC - Mechanical 10:37:11talk to you later...beki 10:37:52Ok I'll be hereCSCEC - Mechanical 10:50:51ALan is here, we made a sample of jet nozzles on the pole.He is checking the sample.beki 10:51:40Did you see it alaready?CSCEC - Mechanical 10:52:08Yes.beki 10:53:42You are very precise in answering... I would like to know what you thought of it, dioes it look good?CSCEC - Mechanical 10:56:16I will send a picture to you, it is roughly manufactured because time limited, but not too bad.CSCEC - Mechanical 10:58:20I should leave for lunch.I am really worried about the noise calculation.Because I have no chance to change the equipment.CSCEC - Mechanical 10:58:39Talk to you later...beki 10:59:11There is big risk..beki 10:59:23Talk to you when you are back.CSCEC - Mechanical 12:19:08Hi, I am back.beki 12:20:22Hi I am still hereCSCEC - Mechanical 12:19:53

CSCEC - Mechanical 12:27:52The situation of noise calculation is like this, when MR PU did the calculation he found useing the silencer we choose before can not reduce so much niose in some system. So first he try to change to other kind of silencer but found that pressure drop on the silencer is much higher than last one.beki 12:34:35The situation that you describe does not show me a conclusion.beki 12:35:28It is important to include the number of fans that are in the hall, used for the general roof extract.CSCEC - Mechanical 12:34:43That mean we need higher pressure loss of the fan. But AHU has been orderdbeki 12:36:03Ok, do not panic

beki 12:36:35The pressure drop should be see in relation to the total pressure drop for which the fan has been designedbeki 12:37:34In general this was quite high as I rememberbeki 12:38:46So I suggest you look at the fan curve (should be somewhere available), and add the extra silencer requirement to it.CSCEC - Mechanical 12:38:35I know,but what we choose before is a quite simple silencer the pressure loss is not more than 15pa,if we use now silencer it will be over 100pabeki 12:40:08This 100 Pa is still small in relation to the total pressure drop of the fan (I conveniently hope)CSCEC - Mechanical 12:44:27First of all, I am not sure if the calculation is right or wrong.beki 12:45:36That is a good startCSCEC - Mechanical 12:45:11You feel I am back?beki 12:46:22Absolutely.beki 12:46:53I want to be back too!!CSCEC - Mechanical 12:48:20I want to make it clear myself only. My company can not tolerate any change or daley.No timebeki 13:01:12If you cannot afford any change, then you just have to hope for the best. As I said, for the AHUs it may not be too bad, as in general the fan total pressure is quite high. But be careful with the extract fans !!!!!!

Date:15-03-2012beki 13:03:31In Dubai this has been a desaster, I was there last week and ADPi has to make a change in the design to rectify it. The axial inline fans make a hell of a noise, and apart from that you must add to it that you have a multiple of fans. This is really important !!beki 13:40:52

CSCEC - Mechanical 14:20:31So many thing can not be controlled, also I do not have enough technical knowlege to control.coil water pressure drop is much higher than I suggestted,some of them is higher than 1bar.CSCEC - Mechanical 14:22:29Last year, everything like a dream nowbeki 14:24:42I am afraid that you start to feel desperate. I will really try to help you.beki 14:25:58You must insist that the coils are choosen correct, it immediately and severely affects the pumps !!!! keep in mind that the control valve wil approximately have to double this value !!beki 14:28:47If you are to be held resonsible, you must have your say in this. The coils can in most cases be 'wired up' (tube arrangement) so that the pressure drop is controlled. You shoul keep it at around 0.3 Bar that will give you the 1 Bar required pressure near the AHU, that is wat the calculation should have been based on.beki 14:29:42The coil arrangement can usually be finalised during the production without financial implication.beki 14:35:43

PS. I also dream often about last yearCSCEC - Mechanical 14:36:50Why the pressure drop on pressure independent control valve must be same with AHU? The function of This kind of valve is to keep required volume of water at any situation,right?beki 14:50:40Sorry.. internal discussion and etc. now I can answer a bitbeki 14:55:33In order to control the water flow trhought he coil you will have two valves in series ( that is in case of the pressure independent control valve). I will see if I can draw a picture that shows the required pressure necessary to control the flow through the coil. Be patient.CSCEC - Mechanical 15:00:02In my mind if there is no pressure independent control valve to keep the same pressure drop between the control valve,control water volume will have problem.

beki 15:05:25The task of thje first valve of a pressure indendent control valve is to maintain constant differential pressure over the the second valve which is used for modulating the flow according to the measured value (can be off-coil temperature, room temperature, supply temperature or return temeprature or whatever). The first valve changes position by pure mechanical means as a function of the differential pressure measure over the second valve.beki 15:08:40If the differential pressure over the actual flow control valve (the second in line) is maintained constant, then no change in valve position of this flow control valve is required in case the system pressure changes. This system pressure is dependent on the system pressure losses. These are high under full load and low under low load conditions.beki 15:47:29I am downloading a few catalogues to get the exact figures for the pressure drop that you need to allow for in case you use the pressure independent control valves. Can you do the same? Maybe you have already some manufacturers catalogues for this. The selection of the valve shall depend on the maximum flowrate that you need to control. Each of these valves has a minimum and maximum pressure drop (maximum is used in the case the system pressure is high, minimum is the minimum pressure necessary over the valve in order to get the design flow)CSCEC - Mechanical 15:47:12Yes I haveCSCEC - Mechanical 15:51:16You are right. But I still am not sure why the valve pressure drop should be almost same with the coil.beki 16:07:20Sorry, again held up by discussions. (I seem to have also a job here)beki 16:10:07The minimum pressure drop over the fully open pressure control valve can be found from the manufacturer. I agree with you that this does not need to equal the coil pressure drop, but limitiations are given by the controllability. Have you been able to see some catalogue figures already?CSCEC - Mechanical 16:26:26

First of all，of course you have a job and really life in Beirut.beki 16:28:48Secondly...... ?CSCEC - Mechanical 16:35:27

Secondly, I have not got catalogue figuresbeki 16:44:29

Did you make a commitment to yourself that limits or restricts your replies to me?CSCEC - Mechanical 16:43:44I am serious now, AHU material submittal has been approved, AHU has been ordered now.No one can afford change anything.The whole situation make me feel weak, I really want to run.CSCEC - Mechanical 16:44:00run away

CSCEC - Mechanical 16:48:13It will be very uncomfortable to stay in this situation, I will feel guilty to ask you help me on issue about this project.beki 16:50:03I am away now. I will contact you later.beki 16:58:46Do you feel guilty towards you management or towards me?CSCEC - Mechanical 16:58:04I was in a almost depressed mood again in recent days (before I came here)CSCEC - Mechanical 16:59:30Maybe more guilty towards my managementbeki 17:02:05I cannot guarantee always to be objective, but to run away from the project might affect your opinion about your professional self.CSCEC - Mechanical 17:02:35I think about it so long time, why I often fell so bad? Before, as I have talked with you about my family, I blame that most on situation around me.CSCEC - Mechanical 17:10:46Because of the operation,I stayed at home much longer than expected, have chance to talk to my husband quite well, I can feel how much he cared about me. I should feel very happy, I really happy about that.But at time goes on, I began to feel not so happy unexpectly.CSCEC - Mechanical 17:11:58I want to make it clear, it is not because the relationship between me and my husband.CSCEC - Mechanical 17:16:02I found the problem is on myself, maybe something I did not want to admit.Maybe I am not strong enough to face lift not so satisfied. I hope my English is good enough to make my expression understandble.CSCEC - Mechanical 17:18:39Actually I do not know why there are so many panic in my mind.CSCEC - Mechanical 17:23:39In 2011, I wanted to run away from my panic,so I came to Mauritius, it really gave me a feeling that I became strong and can face more difficulty. Actually it is not so sure as time passed,and I know from the beginning that it so much depend on your help.CSCEC - Mechanical 17:25:36I really love to work together with you, enjoy it so much, because it really make me feel strong.CSCEC - Mechanical 17:29:09Hi, I do not know what you feel after so much I have said.I have thought if it possible I work together with you in Beirut.beki 17:31:41Thanks for writing me so much about you.CSCEC - Mechanical 17:38:22One thing I want to state is I also enjoy the time stay with you without work when we travel together and talk so much together.That also make me feel I will always be so happy and quiet inside.beki 17:44:35

Like I said just before, it is a bit difficult for me to be objective, as I am so driven by the wish to see you and spend time with you. It is nearly 9 month now that we know each other, and all this time you have played such a big role in my life. I am very happy to be able to teach and help you to become stronger, but that is just a part of it. I catch myself having the most unexpected wishes and ideas. I watch (and enjoy) myself having such in increased perception of beauty, .. I like to make pictures, mix them with music, all of this while knowing you. Meeting you has opened a door to another world. I do not know so well how to speak about it, but it is just so wonderful.CSCEC - Mechanical 17:50:00Thank you on all you feeling about me.OK, so much talk today, I wish I do not make you feel uncomfortable.beki 17:54:45You would only make me feel uncomfortable if you were to loose your interest in me. All other is really so good.CSCEC - Mechanical 17:53:17I want to speak with you anytime in my life to make you know me well, I am not so perfect as you think, but I want to show frankly to you who I am.CSCEC - Mechanical 17:55:55I am a person with so many problem in heart need to be solved by herself, I am tring to be more relaxed at any situation I face.beki 17:58:19I do not see you as perfect at all. Neither am I (actually I am much worse). I had an idea a few days ago. It expresses the different ways that we could communicate.CSCEC - Mechanical 17:57:50I will leave and my dinner will be a bowl of instant noodle.beki 18:00:10I compared the situation whereby two peaple play poker, or some other game of cards. In that case the two people cannot show each other what the have, what they plan or what they think. The other situation is wherebyCSCEC - Mechanical 17:59:01Finish that,then I will leavebeki 18:01:24there are two teams, whereby members of the same team could share and communicate openly.beki 18:02:57I think I would like to be with you in the same team (with life as opponent) ...beki 18:03:38

Now you can eat .....CSCEC - Mechanical 18:01:52

beki 07:01:53Meeting time?CSCEC - Mechanical 07:03:37I do not know the exact time, maybe at 8:30.beki 07:04:19I will be very busy today as I have been asked to make the annual report of all our activities.beki 07:05:07I made a very nice program to generate these reports, but I have to fine tune it.

CSCEC - Mechanical 07:06:18Do not worry about mebeki 07:08:00

It is not only worrying for you that I do. I worry a bit for myself alsoCSCEC - Mechanical 07:10:23

At least you are interesting at your job, I know you will be finebeki 07:10:53As often said... Time will show..beki 07:12:37My job is indeed very interesting, but, you as you know, some extra-terrestial influence passed by...beki 07:13:24So suddenly there was not only my job. Ha HA.beki 07:14:19Anyway, now I must finish my program. I would like to wish you something that made your day bright.beki 07:15:56

But what ??beki 15:22:41Hi,are you in?CSCEC - Mechanical 15:22:49Yesbeki 15:24:22I'm in the house working on the programs for the office to show how hard we are working.beki 15:25:03Monday will be back in the office.beki 15:25:52Do you think you will catch up with what they expect from you?CSCEC - Mechanical 15:31:02I can use the same method in last year, no one expect much from me, if I put myself in right position, it will not be so difficult.CSCEC - Mechanical 15:31:39I can use the same method in last year,--BIG MISTAKE--I can notbeki 15:33:12

What shall I say... I am waiting for a solution to pass bybeki 15:33:48Solutions come sometimes by themselves, unexpected.CSCEC - Mechanical 15:34:15

Time will show itself

beki 15:35:22That is right, I am confident that (give it some time) everything will be just fine.beki 15:37:00I think often about the film we saw about the man who was planting trees. In the beginning he did not see much result of his doing, but that becam completely different after some time.beki 15:40:52

Just relax, give things some time, and then when time shows itself ... you'll be ok.CSCEC - Mechanical 15:42:27I am better a lot than yesterdaybeki 15:43:46I you would like, I mean if you feel like it, then Monday we can chat-a-bit after work.CSCEC - Mechanical 15:49:26Ok, I will.beki 15:50:38

I am back to earth try to land softlybeki 09:04:12

beki 09:15:47Actually I know exactly what you mean. Trying go see things realistic, and to adjust our wishes and plans accordingly, so that we shall not loose ourselves while paying the price of disilussions.CSCEC - Mechanical 09:17:37Now I do not feel so bad, I realize I can not face the job in the way I did it with you.I do not have such ability.

beki 09:20:00The ability, as I see it, depends on two main factors. One the technical knowledge, and Two, the confidence in oneself. Which one do you think restricts you the most?CSCEC - Mechanical 09:29:04Confidence in myself, I know.beki 09:32:50

CSCEC - Mechanical 09:33:51My phone can not send message to yoursbeki 09:34:17Probably also lack of confidenceCSCEC - Mechanical 09:34:42

beki 12:33:12Hi, short lunch? I have been kept so busy today with all kind of 'managerial' issues that I struggle with time. Whereas I want so much to tell you a short but interesting story. I hope to find sometime later this afternoon, to write about it, so that I can send it in the evening to you.CSCEC - Mechanical 12:34:59

Waiting patientlyCSCEC - Mechanical 15:03:20I hope you can understand chinese, then I can chat more freely with you

beki 15:06:49It could be easier, but at the other hand I sometimes think that speaking in another language can also have it's advantages as it might reduce the influence of certain inhibitions. As an alternative to the current situation, I could of course try to study chinese..,beki 15:07:43Or we could hire a translator !!!CSCEC - Mechanical 15:07:57

CSCEC - Mechanical 07:44:07I am reading your story. Yesterday we used office project to make a plan for this project until midnight.CSCEC - Mechanical 07:44:21Have not finished yetCSCEC - Mechanical 08:35:06I am not trying to find an alternative route.beki 08:35:11I am away now. I will contact you later.beki 08:42:28The story itself,without comparison mad at the end, is true. I am normally quite shy to tell these things about myself, and therefeor I just never do that. But to you I can. Do you mind, I am writing this to you?CSCEC - Mechanical 08:51:57I just want to be more realistic. I want to treat my life in a objective way.beki 08:52:04I am away now. I will contact you later.CSCEC - Mechanical 08:54:06You do not know how different of my feeling about everything when I was depressed.beki 08:56:37Do you link depression to beign unrealistic ?CSCEC - Mechanical 09:02:18I will answer it later. Usually I feel not so easy to find the right word to describe the situation.If it is clear for me,I will not in such mood fluctuation.beki 09:02:27I am away now. I will contact you later.beki 09:07:15OK, take your time, and choose the right mooment (probably not while making calculatio

It is not urgent, take your time.See you Date:22-03-2012CSCEC - Mechanical 07:36:32

beki 07:38:09Good morning. I just arrived in the office after a wonderfull night's sleep, although I did not managed to dream of your pictures. But when I woke up I realised that I am still very pleasantly impressed by them.beki 07:39:18Before statring my work, I will just have a go at the Run Around Coils.CSCEC - Mechanical 07:40:30I have a good sleep too.7:17:39

Success to send file "GMF-RUN-AROUND.zip"(20.00KB).

beki 08:18:21These are the psy results, I will make also a short description.

beki 08:57:53Explanation of the PSY Chart results :

1. The room load has been taken as primary element.186 kW sensible and 248 kW Latent

2. The Room Discharge Air temperature and final room condition have been taken as secondary elementIn combination with 1. Above this results in a requirement of 36.149 kg/s supply air flow

3. Having set the desired room condition as 24 DegrC at 65% RH, it follows that with a room discharge temperature of 19 Degr CThe discharge air Relative Humidity shall have to be 70% to satisfy this

4. The calculated supply air shall flow through all the parts of the system:The upstream Run-Around Coil, the Down Stream Coil and the Airhandler coil itself as well as the Fan and the duct

5. Resulting from 3. Above, the off-coil air, which will be near to saturation, shall be 13.4 Degr C.

6. With an estimated Fan and Duct loss of 55.7 kW, the Supply Air temperature coming out of the AHU (After the run-around coil) should be 17.5 Degr C

7. This requires a re-heat for the Off Coil air from 13.4 DegrC to 17.5 Degr C which needs around 150 kW (for the 36.149 kg/s air)

8. This re-heat shall be taken from the outdoor air using the upstream Run Around Coil.

9. The pre-cooling that this will result in could be a combination of sensible and latent (condensation), with a ratio between these two values depending on how the coil is made.

10. In any case however, it will always take the same amount of heat from the incoming air stream to heat up the outgoing air, so it is not important for the energy balance to know this ratio.

11. HAVING TO RUN AROUND COILS, ONE UPSTREAM, AND ONE DOWNSTRAM THE AHU COILTHE FINAL RESULTS FOR THE AHU COIL OF AHU01-02 SHALL BE:AIR FLOW: 36.149 kg/s – COOLING COIL CAPACITY 1822.4 kW

12. GMF’s CONCLUSION THAT THIS VALUE SHALL BE 2 x 465 = 930 Kw IS THEREFORE NOT CORRECT

beki 09:06:09

Hi, I also sent these notes to Green Grass via QQmail.beki 09:08:52I have not tried to argue about the correctness of the load calculation, as that could better be done separately. The report on the recommendations by GMF is purely based on analysing the presented calculations only.beki 09:11:01I Hope to have followed the guidelines of simplicity to your satisfaction..BekiCSCEC - Mechanical 09:14:01It is clear. I am curious that the precooling coil and reheat coil can really work.The water in the coil should be chilled water ,temperature should above off coil temperature (main coil) 13dreg. It is possible to use the chilled water from the main system?beki 09:18:55This question is based on a misunderstanding of the concept of run around coils. The water through these coils shall run around, going from the upstream coil to the downstream coil and then coming back to the upstream coil. This is achieved by putting a pump somewhere in this line. The temperature of this water shall result from the heating up in the upstream coil followed up by the cooling down while going through the coil through which the cold air from the AHU flows. No water is added into this cirucaltion system. The temperatures of this water at various places in the circuit can be calculated.beki 09:59:43I AM PREPARING FOR YOU A VERY SIMPLE EXPLANATION OF THE RUN-AROUND CIRCUIT WITH FLOWS AND TEMPERATURESbeki 10:02:38FIRST THE DIAGRAMbeki 10:02:50

beki 08:11:27Slept well? (like me)CSCEC - Mechanical 08:25:26It is hot last night, I slept late.beki 08:35:26I have a small question. Before you had sent me your 'pictures' did you have any dream about it? I ask you this because not long before the day that I saw these I had a very strange and for me unusual dream. I was looking at the head of a woman that was being sliced so that I saw the inside of it. It was rather cruel, a kind of torture, and eventuall when the slicing came more to the inside 'they' ate some piece of it. Then later when I 'studied' your photos a bit more in detail (sorry for the intrusion), I recognised that also there are images as if the head is sliced (from the back in that case). So this morning I was wondering if you had any scary phantasy images of it.CSCEC - Mechanical 08:56:36

No,I have not had such dream.Your dream is really scared than the picture I sent.beki 08:59:13Yes my dream was very weird, your pictures though are really amazing.beki 09:55:23Hi, just to let you know that I will be out of the office for an hour or so..CSCEC - Mechanical 09:56:28I will be in the office today.beki 13:40:29About the chilled water control valves for the AHUS.

CSCEC - Mechanical 14:43:25Thank you，my doctorbeki 14:44:23

If you take it as advice, that's OK, but actually I that is what I just did in lunch time.beki 14:46:01And the hot chocolate was inspired by the memory of you.beki 14:57:35

CSCEC - Mechanical 15:00:36Bleed drain solenoid valve operation: When the cooling tower is operating, open and closethe valve via a signal from a conductivity sensor in the pond water. Prevent the make-upwater supply valve from opening when the bleed valve is open.beki 15:01:57That is not what we wrote and put in the drawing at earlier stage.CSCEC - Mechanical 15:02:58This is from ADPI spec. It has been changed.sesors will be put in the basin of cooling towerCSCEC - Mechanical 15:03:44or in the header of the outlet from the cooling towerbeki 15:04:55This will of course work, but is more expensive, also more risk of failure due to dependency on sensor.CSCEC - Mechanical 15:06:09My questine is if the water supply valve will be closed when the drain valve open, is that mean this operation can only be taken when the tower is not working.beki 15:06:42No that is a misuderstandingCSCEC - Mechanical 15:07:14Please explain for mebeki 15:07:32Yes my studentbeki 15:09:43There are two water inlets, one the warm water coming out from the chiller (condensor circuit) at aound 37 Degr C as I remember, and secondly the water makeup to make up for the water that is lost due to evaporation.beki 15:10:33If you close the water make-up then the water level gradually lowers in the basinCSCEC - Mechanical 15:10:38I UNDERSTAND IT IS ON THE MAKEUP WATER SUPPLYbeki 15:12:05The make-up comes directly from the town-water supply (after some initial chemical dosing)beki 15:13:19Blow down operation takes water out from the system. That can be done anywhere in the circuit

beki 15:15:21One thing to consider is the amount of blowdown that is required. When I was in Mauritius I made some calculation about this, based also on some reference books, I think from ASRAE. The idea is to limit the concentration of dissolved solids, and therefore the rate depends in fact on the water qualityCSCEC - Mechanical 15:17:51THE BLEED DRAIN VALVE CAN NOT BE INSTALL ON THE DRAIN PIPE FROM THE BASIN, IT SHOULD BE IN THE CIRCUIT OF THE COOLING TOWER,LIKE WHERE YOU HAVE POSIONEDCSCEC - Mechanical 15:18:18

beki 15:20:16If the water quality is constant then the amount of water to blow down into the drain is also a constant percentage of the circulated water, and therefor I had suggested this to be taken from the warm condensor water circuit directly after the inlet valve.beki 15:20:47By the way your picture did not arrive (it shows broken)beki 15:21:35I think your internet connection is ver bad, you go on/off line all the timebeki 15:30:15You could combine the method that I suggested, that is taking the blow down water frrom a tap-off with globe valve to set the flowrate as a percentage of the circulated water, followed by a solenoid valve that alows this drain off only in case the concentration of salts has become too high. in that case you have an easy override facility in case the sensor does not work , you just open the solenoid and let to water go out contantly at the carefully set rate whenever the tower is in operation.beki 15:32:51To prevent new water to enter the basin, I think is not necessary at all. The sensor reading may be affected only if it is not place in the right position. If the sensor is placed just before the inlet of the cooling tower, then the system will work fine.beki 15:35:02If you put the sensor in the basin, the reading may be affected by the entering make-up water, but still in order to understand the situation well you should make a calculation about the flow rates that are applicable.beki 15:35:37Do you want me to explain better? or make some calcualtions?beki 15:37:52热巧克力、乳酪蛋糕和有些演算beki 15:54:30

Hi, did you fall asleep?CSCEC - Mechanical 15:56:42The makeup water pipe has a ball cock in the basin, is there any contridiction, the water level is lower than set level but the motorise valve wont open because drain valve is in operation position?beki 16:00:48

I do now understand you fully, you speak about two valves, the ball cock for the make-up and a motorised valve. I assume the motorised valve is meant to circulate the condensor water coming from the chiller into the cooling tower. If that is the case, I do not see a reason for that valve not to open.

CSCEC - Mechanical 16:52:06THAT MEAN WHEN THE BLEED DRAIN VALVE IS OPEN, ENEN WATER IN THE BASIN IS LOWER THAN THE LEVEL NEED TO HAVE MAKEUO WATER, THE MOTORISED VALVE WILL NOT OPEN.THE FUNCTION OF THIS TWO VALVES MAKE ME COFUSSEDbeki 16:52:14Yes this is very clear, but your initial conclusion that this can only be done if the tower is not in use is not correct. I think to gate a better understadning of the ractical operation you should take into account the actual water flows that we are talking about. Like in my proposal the water is continuosly drained while the twoer is in operation. That should then of course never allow the make-up valve to be open. If you want to drain off when the sensor in the basin tells you to do so, then how much and therefore how long do you have to drain off???????? Whilebeki 16:53:25I will make a picture.CSCEC - Mechanical 16:55:06I WILL NEVER UNDERSTANDbeki 16:56:37Now I really sense DESPERATION !!!!

beki 12:37:26Will you stay long i the office today?CSCEC - Mechanical 12:37:17After dinner?beki 12:38:42Yes I mean after dinner.CSCEC - Mechanical 12:37:53I will be back in the officebeki 12:40:22Ok. I'll stay aslo a bit late, maybe have some time then to say 'hello and so..'beki 17:25:06

quiet daybeki 18:00:23Are you in?CSCEC - Mechanical 18:12:09

beki 18:14:35HiCSCEC - Mechanical 18:12:49hibeki 18:15:46The exact second that I finished with my meeting here you appeared..CSCEC - Mechanical 18:14:37I am just back to officebeki 18:17:01How was your today's day, still a bit difficult?CSCEC - Mechanical 18:17:15The difficulty is not from others, is from the inside of myselfbeki 18:20:49

I want so much to help you, I wish there is such way to do that ..beki 18:22:52For myself there are also issues that are just from inside me. And is is actually always kept inside. I do not discuss my very personal issues with anybody.beki 18:23:56I remember rhe conversation we had in the beginning when you explained me the situation with your son and with the parents of your husband.beki 18:25:06At that time I felt so comfortable and safe with you. That made me also realise many things about myself, just because I did not have to hide it.beki 18:26:55Now that I am so far away from you, I am still missing you so very much. And I ask myself why that is so strong.beki 18:28:38There shall be more than one reason for this, but one of them I think is that in fact I am quite lonely. Not that I suffered from that, in fact I often prefer to be alone.beki 18:30:36But having felt the opportunity to share 'inside' things, I think has made we want to come out of so much silence. (Bit difficult expressed, sorry)CSCEC - Mechanical 18:29:16I would like to listen to your story, if you do not mind I do not reply much.beki 18:32:27I would like to continue, you do not have to reply, just for me to know that you listen is enough.beki 18:33:46Maybe we have a build in need to feel connected with another person. This sounds a bit foolish maybe.beki 18:35:42I have made it a habit all my life to have my strong emotions hidden, that was the rule I learned from childhood. And I never thought it would become a wish of mine to break that rule.beki 18:36:56But the simplicity of knowing 'someone like you' has made me see and think a bit different.CSCEC - Mechanical 18:36:54I think I am healthy and strong at that timebeki 18:39:32I told you that I have the wish to write to you, and that I even want to do that 'by hand' instead of all this typing. It is just to express myself to you in a way that is so real, so real as I never deared to feel.beki 18:40:21It is not so much the healthy and strong. There is something else, something that seems not to depend on anything ...beki 18:41:16Of course that is not the case, of course it depends on things, but I cannot make out what exactly that is, actually I do not knw at all what it is.

beki 18:43:04Because it is all so impractical, I try really to understand what is going on.beki 18:44:14Anyway, I realise that you feel very uncomfortable now, and you make it clear to me that you feel so powerless.beki 18:45:10That affects me a lot. Not that I suffer from that, no it creates in me the wish to help you, but of course I have no clue how to do that.beki 18:48:14Sometimes you speak in a way that transfers fear to me. I feel frightened when I place myself in your position.CSCEC - Mechanical 18:51:23I know you want to help me, I thought about myself and realize that everytime Ifeel powerless I had already decided that I do not want to do anything,terrible.beki 18:54:05When trying to find a way to come to Mauritius, I think of the potential problems that are there, and that I expect to arise when your project will come in delay. In my opinion CSCEC is not responsible for the delays that have resulted from the wrong design and from the wrong advices from the design consutant. If the project comes in delay I think CSCEC should take these things into acount. But who is going to do that? When I think about this I feel that your opinion about yourself is not allowing and therefore not letting you become involved.beki 18:56:10I cannot force or push you, that would actually have the opposite effect, you will pull back.beki 19:00:55Recently I hear a few times a chinese 'wisdom' that speaks about conquering the dragon. Something like, "you should first make it beautiful"beki 19:01:11Maybe you know more about that.beki 19:01:50One thing I also try to understand is the feeling of depression, to feel so low.beki 19:05:03Sometimes I think that we can feel like that without knowing why, because we may have wishes that are repressed, that are subconscious, but still deep within 'our brains' we are trying to find a way to achieve in getting what we want (probably need). And if there apears to be no solution... then we may just start to feel the result of desperation,beki 19:10:36For me, I do not feel such depression now, but there have been periods in my life that it was really bad. I hope that I will not start to feel so low if I realise how difficult it will be to meet you again. My work is fine, I have a well paid job, and many people can envy my situation. But..beki 19:11:43There are recently moments that I am so surprised and even shocked by my own feelings.beki 19:15:49I do not know how I came to this crazy image.. but as a flash it came in my mind that if I

were to die, I would like to be with you. That is of course very very egoistic, because it does not take into account how you would feel that, but at the other hand it expresses how I wish to feel close to you. Not because of you being healthy or strong as you just mentioned, but because of something that I still do not understand. I hope I do not upset you by telling you this.CSCEC - Mechanical 19:19:23I am not upsetbeki 19:30:05I will be going to Paris next week. Then I will take also the opportunity to go for a few days to Holland to see my sister. From Tuesday I will be 'on the run'

'On the run' is Somehow a good expression for how I live.What will happen if I sit down and start to realise that life is slowly passing by without me taking fully part in it.

Once I wrote about the short time of being alive after which forever not being there anymore. That is not something depressing, but it makes me focus on self awareness.beki 19:37:01I said many things to you, it is maybe time to go now. I am a bit silent inside now.beki 19:39:39What will you do now?CSCEC - Mechanical 19:40:02Stay a while in office.CSCEC - Mechanical 19:40:46So I will not see you from next weekbeki 19:44:01I will be on places probably without internet.beki 19:44:41But I would like to phone you sometimes if that is OK with you.CSCEC - Mechanical 19:43:27I try so many times, all my message has not been sent successfullyCSCEC - Mechanical 19:47:15Phone me, you can not get message back.beki 19:50:55I will, but in any case I will be in the office until tuesday lunchtime.beki 19:51:48Will you be in the office next week monday ?Date:03-04-2012beki 07:46:11

A good morning to you too, Lubeki 07:46:43I will indeed be busy, but never I will be too busy to say some things to youbeki 07:47:09

Also some nice things

beki 08:10:35Hi, how are your submittals going. I have taken so now and then quick look, and I am seeing a lot of progress, but also some unfortunate results, such as today's rejection of the chillers FAT. LBG-TRANSMIT-003329. Are you also involved in that?

CSCEC - Mechanical 08:12:46I am not involved in that.beki 08:13:06Good for you. Date:30-03-2012CSCEC - Mechanical 19:50:24I willbeki 19:53:34

Ok, then I hope to seen you again on Monday..CSCEC - Mechanical 19:52:47


beki 07:37:46

Hello, good morning to you too.CSCEC - Mechanical 07:39:19How about your weekend?beki 07:39:48Better you tell about yours..CSCEC - Mechanical 07:45:49some of my colleagues drived around the beach and had lunch in a resterautbeki 07:46:41Were you also with them?CSCEC - Mechanical 07:47:35Yes, I wasCSCEC - Mechanical 07:48:50I am sorry to make you feel bad about my silence in these daysbeki 07:50:59You have not made me feel bad.beki 07:59:30I am trying to understand myself better. I found something to explain, by comparing myself. I try later today to tell you. Maybe you will understand, I really hope that. Now, in the office, I am working on the meetings that I shall have this week in Paris with ADPi for the new project. I feel I have been neglecting this part of the work a bit, especially after finding out theat I missed one e-mail. After the meetings I will go to Holland, to

my sister for a day or two, and then back to Beirut for a day. I have been asked to go to Dubai after that to renew my registration there as member of the association for engineers. I need and hope to find more time to write to you.CSCEC - Mechanical 08:04:18I know you are busy and managed so well, if I have the ability I will feel very happy and

relax.beki 08:26:40Now I have to go for another blood test. Yearly renewal of the ADPi insurance. Will be back after two hours maybe.CSCEC - Mechanical 08:28:14

Go with you?CSCEC - Mechanical 08:28:36

beki 08:29:12

Ok.. I hope I have enough blood left to write something...beki 10:51:44Back from Blood Test and Check-Up. Doctor was an enthousiastic painter, who wanted firs to show me his collection of which he made a series of photo placed in an album. I seem to have past all tests. And blood still available to write.beki 13:26:27

In?CSCEC - Mechanical 13:35:10

I can not get in in the noon.beki 13:43:42Ok, I will try to send you something in different way later. Will you be there aftr dinner maybe?CSCEC - Mechanical 13:43:20I will be backbeki 13:44:56Fine. See you then, although I will not be that long in the office.CSCEC - Mechanical 13:44:52

beki 13:46:42


Do you know what is low temperature independent unit?The set point will be 12 degree.beki 13:53:21I am away now. I will contact you later.beki 15:01:27Just back from Lunch (with book)... Low temperature independent unit... I guess it is for food or medicins. The 12 Degrees cannot be guaranteed to be achieved with the chilled water, especially as the chilled water temeprature shall fluctuate so now and then, so you must use an independent Direct Expansion unit. An electriallly driven compressor filling a condensor and an expansion coil in combination with a fan. Those are the main components.CSCEC - Mechanical 15:07:09It is asked to be used in garbage certer in the terminal buildingbeki 15:12:39Ok, that has in a way to do with food, to prevent it from starting to smell when wating for it's disposal to the waste disposal plant (may not be on the airport itself). This space needs to be maintained at low temperature. The use of independent cooling based on evaporation of a refrigerant in an expansion coil. This could be a package unit (all compaonents in one) with ducted air to and from the room, or split system whereby the expansion coil is in the space and the compressor and condesor are in a separate location.CSCEC - Mechanical 15:18:35

OK,CSCEC - Mechanical 15:20:05I will ask more information from the supplierCSCEC - Mechanical 18:02:56

beki 18:05:20Hi, I am writing something.. (to you)CSCEC - Mechanical 18:04:24You will not come to office tomorrow, right?beki 18:07:52I will come in the morning , My flight leaves at 16:00 from Beirut, so I will stay until 13:00 in the office.beki 18:33:59

beki 12:43:20in a meeting with ADPibeki 12:43:44I am the only one from ADPIME tpo join this hereCSCEC - Mechanical 12:47:59Yesterday they sent all documents about Colombo programme to a public mailbox. Did you know that?beki 12:49:47yes I amd downloading during the meetingsbeki 13:04:28

Multitasking..Holding the meeting with ADPi,Downloading Files for ColomboSaying Hello to you

CSCEC - Mechanical 13:05:40HOW GET INTO EXCEL VBA? I WANT TO SEE THE FOMULAR, BUT I FORGET HOW TO GET INbeki 13:08:49Press ALT F11beki 13:35:58

Did you manage to get VBA alive?

It is a very interesting tool, it would be so nice if you learn it

Now I shall be going for lunch (very luxurious cantina of ADPi)After that I may not have access to internet.

Anyway nice to have had some contact with you

beki 13:50:06Hi,beki 13:50:21

Still there?beki 13:53:16Now I am goting for lunch, I will leave this computer on..CSCEC - Mechanical 15:21:56PLEASE WRITE ME THE FOMULAR FOR ADD_DBbeki 15:27:22Hi, you mean the additions for two noises of a certain sound pressure level?CSCEC - Mechanical 15:27:07YES,THE FORMULAR YOU USED IN THE EXCELbeki 15:29:12OK, I will try to find it. I have a few minutes before my next meeting which will be in another room (I will leave computer here open)CSCEC - Mechanical 15:29:12OK, take your timebeki 15:31:24

Ha Ha, Whatever time I take is practically stolen but I want to do it for youbeki 15:35:35The formula that I used was:Public Function ADD_DB(db1 As Double, db2 As Double) As DoubleADD_DB = db1 + 10 * Log10(1 + 10 ^ ((db2 - db1) / 10))End Function

beki 15:35:55That Means:beki 15:37:46You subtract the two db figures (to get positive result put) then divide the anwer of that by 10 and use the result of that to raise it to the power 10, then...beki 15:38:50You add then 1 to that result of: 10 raised to the power of (db2-db1)/10beki 15:40:08

of that answer you take the logarithme (base 10), multiply the result with 10 and add it to the smallest of the two db valuesbeki 15:43:15So for example, if the two db values are the same (good test for formula) than db2-db1= 0 , 0/10 =0 , and then 10 to the power 0 is 1. Then you have to add 1, so 1+1=2 and the logaritme of 2 = 0.3 (around) and when you multiply that with 10 you see that you should add 3 to the initial db valuebeki 15:43:50Got it ??CSCEC - Mechanical 15:43:13WHAT I GET FROM THE REFERENCE BOOK IS 10*LOG(10^DB1/10+10^DB2/10)beki 15:47:00I will check, (you can check also by knowing that if you add two equal db values you must add 3 to it to get the final value, that is without doubt correct.beki 15:50:56I have to go now to the meeting, I have obtained the formula in my spreadhseet myself and I know it is good.CSCEC - Mechanical 15:50:16

See you laterbeki 15:52:17Ok I hope to see you.. I will come back from this meeting later, maybe you are still there,

otherwiseCSCEC - Mechanical 15:51:18

beki 18:12:01Hi I am leaving now, just have to say good bey to some VIPs. Hope you find your way in VBA or other ways of calculation the noise. I will hav another look later on your suggest

ed formula. Beki Date:07-04-20129:16:05


Date:10-04-2012beki 09:26:44Good morning from Paris again. I came back here to have some meetings regarding the Keel City project in Colombo withMr. Samaha and other ADPi directors. Will see what it is, and may bring. I have downloaded all the documentation that was put on the website, and printed in my sister's house in Holland the MEP design briefs. I do still not know what is exactly required from ADPi - ADPIME.but what I know is that I am already in between two fires (seems to be fate of my life).beki 09:55:33
