A

The principle of an absorption machine is the exchange of heat. In a heat pump, there are four basic heat ex-change surfaces: the evaporator, the absorber, the gen-erator, and the condenser (See Figure 1 on page 14).

Like any heating and cooling system, a heat pump uses evaporation and condensation to remove heat. The ab-sorption cycle uses deionized water as the refrigerant and lithium bromide (LiBr) as the absorbent. The en-tire process occurs in almost a complete vacuum.

HEAT PUMP COMPONENTSThe absorption heat-pump unit consists of the follow-ing components:

• evaporator

• absorber

• condenser

• generator

• solution heat exchangers to heighten the cycle ef-ficiency

• pumps to circulate the refrigerant and solution in the cycle

• purge unit to remove non-condensable gas from the machine

CONTROL PANELThe absorption heat-pump comes with a factory mounted and pre-wired control system. The control panel enclosure is equipped with a hinged access door with lock and key. The control panel includes a touch panel showing all system parameters in various lan-guages with numeric data in metric units. For details of the control panel, see SECTION 6 – OPERATION.

The unit is also equipped with two methods to start and stop operations:

• touch panel

• external signal

SECTION 2 – PRODUCT DESCRIPTION FORM 155.36-ICOM2.EN.CE/GBISSUE DATE: 04/05/2019

HOW IT WORKS

The single effect (steam driven) absorption heat-pump uses deionized water as the refrigerant and lithium bro-mide (LiBr) solution as the absorbent. It is the strong affinity that these two substances have for one another that makes the cycle work.

The vapor pressure of the lithium bromide solution is lower than the vapor pressure of the refrigerant. The vapor pressure of the LiBr solution is directly related to the amount of refrigerant (water) present in the solu-tion with the LiBr and the solution temperature.

TWO STEP EVAPORATOR - ABSORBERThe evaporator and the absorber are split into two sec-tions. This design allows the cycle concentration to be lower than a conventional absorber or evaporator. The lower concentrations means the unit is more reliable and operates with increased efficiency. In addition, it has a lower corrosion potential and uses lower temper-ature steam in the generator.

The heat source water flows through both evaporator sections. It enters the lower evaporator tubes first. It then moves to and through the upper evaporator before it leaves the heat pump.

Each evaporator works at a different temperature and pressure. The refrigerant in the lower evaporator boils at a higher temperature than in the upper one. The waste heat from the heat source water can be extracted in two steps.

The absorber is split into two sections as well. A strong solution enters the top of the upper absorber. It flows down through the upper absorber bundle.

The upper bundle operates at a lower vapor pressure. The lower vapor pressure means that the upper evapo-rator can operate at a lower pressure and temperature.

The solution then flows into the top of the lower ab-sorber section. When the LiBr solution enters the lower absorber section, it is already diluted by the refriger-ant vapor that boiled off in the upper evaporator. Since the lower evaporator is where the first step of the heat source water heat recovery process takes place, the va-por pressure of the solution is enough to maintain the temperature and pressure in the lower evaporator.

The water from the heating load facility enters the low-er absorber section first. This helps to keep the vapor pressure of the weaker solution as low as possible.

SOLUTION HEAT EXCHANGERAs the dilute LiBr solution is sent to the generator, it passes through a solution heat exchanger first. There, the solution is pre-heated before it enters the generator.

The pre-heating reduces the driving heat source re-quirement in the generator. It also helps to cool the concentrated solution before it enters the upper absorb-er section.

GENERATORThe generator section is a falling film design. The steam passes through the stainless steel tubes. It then heats the pre-heated dilute solution. The pre-heated dilute solution arrives from the high temperature heat exchanger and the steam condensate heat exchanger.

The refrigerant (water) vapors move to the condenser. The LiBr solution left behind is a concentrated (strong) solution. The solution is cooled before it is sent to the upper absorber.

CONDENSERThe refrigerant vapors condense into liquid refrigerant in the condenser section. The hot water aids the pro-cess. The refrigerant water is sent to the lower evapo-rator section through the refrigerant condensate heat exchanger.

CRYSTALLIZATIONAll absorption heat-pumps that use lithium bromide and water as the solution and refrigerant pair are sub-ject to crystallization. This is due to the fact that some areas of the unit operate with solution liquid concentra-tion levels that are only possible at temperatures that are higher than the normal ambient temperature sur-rounding the unit. For example, the solution concentra-tion in the generator of a single effect absorption unit is typically 64.3% lithium bromide by weight. That concentration begins to crystallize at 43.3°C (110°F).

Crystallization happens when the LiBr solution tem-perature drops too low or the concentration is too high. The LiBr solution becomes like slush. At this point, the LiBr solution cannot absorb any more water and will start to solidify (crystallize).

Crystallization occurs in the solution heat exchanger. In addition, it may happen in the generator. It also hap-pens in pipes that are not well insulated and are located in rooms where the temperature can affect the solution as it moves through the pipes.

You can prevent crystallization by making sure you keep the solution temperature high and the solution concentration at the optimum percentage (64%).

Since the solution temperature in the generator is high enough, no crystallization will occur as long as the higher temperature is maintained. Before the unit is shut down, make sure the solution is sufficiently di-luted in all areas of the unit to prevent crystallization during the off cycle. Remember, the solution tempera-ture will eventually become equal to the ambient tem-perature of the room.

All units employ some sort of dilution cycle, which fulfills this requirement. As long as the unit is allowed to dilute itself during an orderly shutdown sequence, the unit should be able to sit idle at fairly low plant room ambient temperatures for extended periods of time without any threat of crystallization. Typically, after a dilution cycle, the average solution concentra-tion within the heat pump will be below 45% lithium bromide by weight. Although the crystallization line on Figure 49 on page 104 or Figure 50 on page 105 does not extend that far, you can see that the solution at a 45% concentration should not crystallize at normal ambient temperatures.

WHY DOES CRYSTALLIZATION OCCUR?The most common reason for crystallization is pow-er failure. If a heat pump is running at full load and power is interrupted for a long time, the concentrated solution in the high side of the unit eventually cools down. Since no dilution cycle was performed, the solu-tion concentration in some areas of the unit will still be high. If the temperature of this concentrated solution is allowed to fall low enough, the solution will reach its crystallization point. Plant room temperature, insula-tion quality and the solution concentration all play a part in the determination of how long it will take before the unit will crystallize. See SECTION 7 – MAINTE-NANCE for information on water quality control and crystallization. The Duhring Diagram (PTX Chart) shows the specific temperatures and pressures of the crystallization area. See Figure 49 on page 104 and Figure 50 on page 105.

PRECAUTIONS FOR USEA caution label for a rotating object is pasted around the belt cover of the vacuum pump. When replacing the oil in the vacuum pump, belt, or performing main-tenance work, stop the heat pump. Be sure to turn off the main circuit breaker (MCB1) and lockout or tagout the unit. If you do not, the vacuum pump could start abruptly and cause injury to you or damage to the unit.

Do not place anything heavy on the machine or its con-trol panel. It may fall and injure someone.

Do not climb up the machine without a safety harness. Contact your local Johnson Controls service office for inspection and maintenance of the machine. Improper inspection and maintenance can not only cause a ma-chine problem but also injure workers.

Keep the hot water, heat source water, and steam under the maximum usage pressure. If they exceed the maxi-mum usage pressure, pipes may spout or leak. That, in turn, may cause an electric shock and a burn.

Do not change the set values of the safety devices and protective devices. Operation with incorrect values can cause problems.

The shut off valve for the pressure release valve must remain open except during servicing. The unit must never be operated with this shut off valve closed.

A caution label for high temperature is pasted at the control panel, solution pump, and vacuum pump. Be sure not to touch the pump during pump operation. It may cause a burn.

Wear protective gloves and goggles when operating the any part of the heat pump.

During service and maintenance work, be sure to turn OFF the main circuit breaker (MCB1) and follow all required lockout or tagout procedures Close the main valve of the steam line. If not, it may cause electric shock and burn.

If the cables of the solution pump, refrigerant pump, or vacuum pump are disconnected for service and main-tenance work, be sure to check the rotating direction of the pump motor. If not, the heat pump may malfunc-tion. When changing the oil in the purge pump, be sure to stop the purge operation.

LEAK TESTINGWhen leak testing, verify the area is properly venti-lated. Failure to do so may result in suffocation.

ELECTRICAL SHOCK CAUTIONSDo not touch the control panel with wet hands. This can cause electric shock. Do not touch the wiring in the control panel.

Other than the control panel and the valves described in the operating manual, do not touch any part of the machine. This can cause a problem and injury.

Apply only the specified source voltage. Application of a different voltage can cause a fire and electric shock.

Welding should only be done in certain circumstances. If welding is done, be careful not to compromise the integrity of the vessel. Prior to welding, be absolutely certain that the electrical system is grounded properly.

Failure to do this can result in electrical shock, injury, or damage to the heat pump.

Do not splash water over the machine and its control panel. This can cause an electric shock.

A warning label for electric shock is pasted at the con-trol panel, solution pump, refrigerant pump, and the terminal box of the vacuum pump motor. Before open-ing the terminal box, be sure to stop the heat pump and turn OFF the main circuit breaker (MCB1).

SECTION 5 - COMMISSIONINGGENERAL GUIDELINES FOR USE

Before OperationCharge the solution and the refrigerant water if the so-lution and refrigerant water is in the barrels during the delivery.

During commissioning, check the motor’s rotating direction of the solution pump, refrigerant pump, and purge pump.

The rotation direction can be quickly tested by using a rotation detector (Bell and Gosset or WILO DKG). If a rotation detector is not available, follow these steps:

The flow of fluid cannot be seen because the solution and refrigerant pumps are hermetically sealed.

1. Remove the plugs at the solution and refrigerant sampling valves.

2. Make sure the valves are completely closed.

3. Confirm that the absorber and the refrigerant tank contain enough solution and refrigerant.

4. Connect a compound gauge (NPT 1/2") to the sampling valve with Teflon tape.

The gauge's scale must be -760 mm Hg. to 2 Kg per cm2g, or -30" Hg. to 30 psig. To prevent corrosion of the gauge, clean it thoroughly and check for leaks after use.

5. Operate the pump and open the valve.

6. Read and record the delivery pressure of the solu-tion pump and the refrigerant pump.

7. Close the valve.

8. Check the pressure readings. See Table 9 on page 38

to see if your pump rotation is in the right direction. The correct direction shows a higher discharge pressure.

The delivery pressure reflects the high vacuum condition of the machine. If the inside pressure is atmospheric, add 1.0 kg per cm (14.3 psig) to the standards in table.

9. Remove the compound gauge.

10. Put the plugs back on the valves.

11. Clean the gauge with water.

12. For the refrigerant, confirm the correct rotation by looking at the refrigerant spray through the sight glass.

After the completion of the equipment work (installa-tion of the heat pump, thermal insulation for cold or hot surfaces), operate the heat pump and measure the noise around the heat pump unit.

The noise data of the heat pump unit is measured in decibels in the factory. See Figure 20 on page 36.

An Earth Leakage Breaker (ELB) MUST be installed on the unit. If it is not, install it before work continues.

The Heat Pump Pre-Start Up and Commissioning Checklist contains specific information for the instal-lation and start-up of the unit. The steps and proce-dures MUST be performed by a YORK/Johnson Con-trols Service person prior to customer use.

Do not run the solution pump without solution. Do not run the refrigerant pump without refrigerant water.

All items on the checklist MUST be completed prior to charging and initial operation. Failure to do this may result in injury, machine malfunction, or damage.

PRECAUTIONS FOR THE USE OF WATERStaining and corrosion of the tubes in the evaporator, absorber, generator, and condenser depends on the quality of the water used as district heating (hot) water and heat source water. As a result, water quality must be checked periodically to prevent problems. If wa-ter quality is not controlled and maintained properly, premature tube failure can result. Causes of bad water quality include:

• Polluted seawater

• Brackish water

• Polluted underground water

Be sure to analyze the heat source and district heating (hot) water within one month after commissioning. See Table 27 on page 62.

Install strainers of 10 mesh and above to the heat source water and the hot water inlets.

Shut off valves will be installed at the customer site in the steam, heat source water, and district heating (hot) water inlets and outlets. Be sure the valves are completely open when supplying water. If not, the wa-ter flow can become turbulent (at the shut off valves) and damage the water chamber case and tubes. When you need to temporarily reduce the quantity of the heat source and district heating (hot) water, use the valves to make adjustments.

When the flow rate change of the heat source water is controlled (if the flow rate change function is in-stalled), the load change speed is limited.

• The load change condition to limit the heat source water temperature at the outlet is ±0.5°C: 1.5% minimum / maximum.

• The critical load change condition to prevent an overcooling trip of the heat pump is 5% minimum / maximum.

Set the steam feed pressure at the inlet of the steam manual valve to its specification. If the pressure is low-er than the specification, performance of the heat pump may drop.

Limit the steam pressure fluctuation to between +0.05 and -0.1 MPa. If the pressure fluctuates too much, con-trol becomes unstable. The valve may start to hunt for the correct district heating (hot) water and heat source water temperature at the outlet. As a result, perfor-mance suffers, and the operation may stop.

Be sure to install a 60 to 70 mesh strainer in front of the steam control valve or steam shut-off valve (option). If the valve gets clogged, the steam flow rate cannot be controlled. If the system has the any of the following, then it is vulnerable to steam leaks when the heat pump stops.

• A non-leak steam control valve or steam conden-sate (drain) control valve is not used

• No steam shut-off valve

• A clogged control valve

Crystallization of the solution in the generator may take place.

Adjust the pressure at the steam drain outlet to the specification point. Use the regulator valve on the fa-cility side to make the adjustment.

If the steam drain or air may flow back while the heat pump is stopped, install a check valve in the middle of the drain return piping. (If two or more heat pumps are installed and the drain return pipes are joined to return the drain to the hot well tank, install the check valve before the junction of the pipes.)

Install a drain trap at the lowest place of the steam con-trol valve or steam shut-off valve inlet side to prevent an inflow of drain material to the generator. And, in-stall a mist separator to minimize mist contained in the steam.

A drain trap does not need to be installed in the steam drain line between the heat pump and the hot well tank. The presence of a drain trap will cause the steam flow to become unstable. In this case, the condensed water draining from the heat pump is sub-cooled enough so that a drain trap is unnecessary.

Isolate the main steam supply valve when servicing the heat pump or during an extended shut down.

JOHNSON CONTROLS40


HOT WATER OUTLET TEMPERATURE CONTROLLERThe district heating (hot) water outlet temperature con-troller (23A) is located on the sequencer. It controls the district heating (hot) water outlet temperature.

LIQUID LEVEL GAUGESLiquid level gauges are used to check the condition of the heat pump components.

START THE HEAT PUMPBefore starting the heat pump, review the following:

• Check that the refrigerant blow valve (VR1) is closed.

• Check the degree of the vacuum in the machine. Use the pressure gauge of the generator.

• Check the steam inlet pressure.

• Open the steam supply manual valve and steam drain manual valve.

• Check that the Refrigerant Pump Auto button is pressed.

After the review is complete:

1. Press the OPER. button on the Control Panel to start the heat pump. To start the heat pump from a remote location, enter the remote start signal.

When the heat pump starts, the following occurs:

• The solution circulation pump, solution spray pump, and refrigerant pump start.

• The steam control valve or steam drain control valve, steam drain solenoid valve and steam shut-off (option) valve open.

• Tthe steam volume is controlled automatically according to the heating load. The Temperature Control lamp lights.

STOP THE HEAT PUMPTo stop the heat pump, press the STOP button on the Control Panel, or to stop the heat pump from a remote location, enter the remote stop signal.

When the heat pump stops, the following occurs:

1. The steam control valve or steam drain control valve, steam drain solenoid valve delay to stop and the steam shut-off (option) valve close.

2. The dilution operation starts and continues for 15 minutes.

During the dilution operation, the solu-tion circulation pump, solution spray pump, and refrigerant pump operate.

3. Once the dilution operation is complete, the solu-tion circulation pump, solution spray pump, and refrigerant pump stop.

4. Then, the heat source water pump, and district heating (hot) water pump stop.

5. Close the steam supply manual valve and steam drain manual valve.

VALVE INSPECTIONThe heat pump is equipped with a refrigerant manual blow valve (VR1) that blows refrigerant from the re-frigerant tank to the absorber. See Figure 42 on page 97.

The valve must not be tampered with or have its set-tings changed. Daily maintenance or inspection is the only reason to touch the valve.

During service and maintenance work, be sure to turn OFF the main circuit breaker (MCB1) and close the main valve of the steam line. If you do not, it may cause electric shock or a burn.

Contact your local Johnson Controls Service Office for inspection and mainte-nance of the machine. Improper inspec-tion and maintenance can not only cause a machine problem but also injure workers.

Solenoid ValvesThe absorption heat pump is equipped with the follow-ing solenoid valves.

START THE HEAT PUMP AFTER IT HAS BEEN STOPPED FOR A LONG PERIODWhen you start the heat pump after it has not run for a long time, use the following procedure.

1. Check the insulation of the Control Center and the electric system.

2. Check the operation of the Control Center and the safety devices.

3. Check that the refrigerant blow valve VR1 is closed.

4. Check the vacuum level in the machine. Use the pressure gauge of the generator.

It should be less than -0.1 MPaG.

5. Check the source water and hot water supply.

6. Check the steam pressure.

7. Press the Refrigerant Pump Stop button.

If the checks show no problems, start the heat pump.

Checks After Operation Starts• 10-15 minutes after the heat pump and the solu-

tion pump start, check the level gauge of the re-frigerant tank.

• If the refrigerant level is within the level gauge, press the Refrigerant Pump Auto button.

• Observe the operation for a while. Check that the refrigerant liquid level does not drop.

• Use the procedure shown in Purge Procedure on page 81 to purge non-condensable gas from the low pressure side (absorber).

Remember: Only deionized water may be used as the refrigerant in the heat pump!

PURGE PROCEDURENon-condensable gas, including air, must be purged from the heat pump to maintain its performance and prevent deterioration of its internal parts. This heat pump has an automatic purge system.

The automatic purge is done by the water jet purge sys-tem. The system uses the heat source water pressure as the driving force. It ejects non-condensable gas from the purge tank via an aspirator.

Even if the automatic purge mode is used during nor-mal operation, perform the manual operation for the purging tank and absorber periodically. For the purging period, see Table 23 on page 91.

During a water jet purge, put the uncon-nected end of the water discharge hose in a drain ditch or drain port. If you do not, flooding may result.

Be sure the one end of the hose is not connected to anything. Otherwise, the automatic purge will not work properly

JOHNSON CONTROLS82


PERFORMANCE CHECK METHOD OF VACUUM PUMPFor commissioning and regular maintenance, check the performance of the vacuum pump first according to the following procedure.

1. Check the oil level in the vacuum pump.

2. If the oil is cloudy, it contains water and must be replaced with new oil.

See the Operation Manual for the Vacuum Pump for more information on how to change the oil.

3. Open the gas ballast.

If the purge unit is operated with the gas ballast closed, water is left in the oil. The oil will need to be replaced more frequently.

4. Set the valves according to pattern D shown in Table 22 on page 86 .

5. Press the Purge Pump ON button. The vacuum pump starts.

6. 1-2 minutes after the vacuum pump starts, con-firm that the vacuum gauge stands at 0 - approxi-mately 1 kPa.abs.

7. Press the Purge Pump OFF button. The vacuum pump stops.

8. Wait for 30 minutes.

9. Confirm that the vacuum down is within 2 kPa.

MANUAL METHOD TO PURGE NON-CONDENSABLE GAS DIRECTLY FROM ABSORBER WITH VACUUM PUMPWhen the heat pump operates at a lower capacity than usual for a long period of time or when it restarts after a power failure, the absorber may contain non-condens-able gases. If the machine starts under these conditions, its performance and efficiency go down. If this hap-pens, purge non-condensable gas directly from the ab-sorber manually according to the following procedure.

Do NOT purge using the vacuum pump while the heat pump operates. The vacu-um pump may fail.

1. Set the valves according to pattern D shown in Table 22 on page 86.


3. After step 2 begins, confirm that vacuum gauge stands at 0 ~1 kPa.abs.

4. Reading the vacuum gauge, open valve VP9 grad-ually. Confirm that the pressure on the vacuum gauge increases slightly.

If the pressure decreases when valve VP9 opens, the vacuum pump capacity is insuf-ficient. Close valve VP9 at once. Check the purge line.

5. If no problems are found, open valve VP9. The valve pattern now matches pattern B shown in Table 22 on page 86.

Make sure the valve is completely open.

6. Continue to purge for 2 to 3 hours.

7. Close valve VP9.


MANUAL METHOD TO PURGE NON-CONDENSABLE GAS FROM PURGING TANK WITH VACUUM PUMPWhile the absorption heat-pump operates, non-con-densable gas collects in the purging tank. You can purge those gases manually using the following procedure.

Do NOT purge using the vacuum pump while the heat pump operates. The vacu-um pump may fail.

1. Set the valves according to pattern D shown in Table 22 on page 86.


3. 3-4 minutes after the vacuum pump starts, con-firm that the vacuum gauge stands at 0~1 kPa.abs.

4. Reading the vacuum gauge, gradually open valve VP8. The valve pattern now matches pattern A shown in Table 22 on page 86.

5. The manual purge procedure is complete when the pressure reaches 3 kPa.abs or less on the vac-uum gauge.

6. Close valve VP8.


JOHNSON CONTROLS 85


7

AUTOMATIC METHOD TO PURGE NON-CONDENSABLE GAS FROM PURGING TANK BY WATER JET PURGE SYSTEMThis heat pump has an automatic purge system. The purge solenoid valves automatically open and close by detecting the pressure inside the purge tank.

1. Set the valves in accordance with the Purge pat-tern C shown in Table 22 on page 86.

2. Press the Manual WJ Purge Auto button.

3. The purge solenoid valves automatically open and close.

During the automatic purge operation, the purge sole-noid valves open when the purging tank pressure in-creases abs and close when it decreases.

When you replace the oil in the vacuum pump or belt or perform maintenance work while the absorption heat pump is running, be sure to turn off the circuit breaker of the vacuum pump in the control panel. If not, the vacuum pump could start abruptly and cause injury.

REFRIGERANT REFINING METHODRemember: Only deionized water may be used as the refrigerant in the heat pump!

With an increase in the operation time of the heat pump, some of the solution can mix in with the refrig-erant. Mixing the solution and the refrigerant lowers the performance of the unit. To prevent this, the refrig-erant must be refined periodically.

Refine the refrigerant according to the following pro-cedure. The heat pump must be operating to refine re-frigerant.

When refining refrigerant, operate the absorption heat-pump under a low load (50% or less) for higher refin-ing efficiency. Note that the performance of the unit is dramatically reduced during the refrigerant refining operation.

1. Remove the cap of the refrigerant manual blow valve VR1.

For the location of the refrigerant manual blow valve, see Figure 45 on page 87.

2. Turn the spindle in the valve to the left using an 8 mm hexagon wrench to start refining the refriger-ant.

3. After the refining process is complete, close the spindle in the valve (turn it to the right until it stops).

4. Return the valve cap. There is an O-ring between the cap and valve. When fitting the cap, make sure that the O-ring is set normally.

The time required for refinement of the refrigerant depends on the current load condition. Constantly check the liquid level in the refrigerant tank while the refrigerant is refined. If the refrigerant liquid level appears in the level gauge of the refrigerant tank, close the valve im-mediately and fully.

MANUAL REFRIGERANT BLOWDOWN AND DILUTING METHODWhen the heat pump stops suddenly due to a power failure, the solution can become crystallized. If this happens, dilute the solution manually according to the following procedure.

Perform the following procedure immedi-ately after the power is restored.

1. Press the Forced Dilution ON button. The solu-tion pump and refrigerant pump start.

2. Remove the cap of the refrigerant manual blow valve VR1.


3. Turn the spindle in the valve to the left with the 8 mm hexagon wrench. The refrigerant in the refrig-erant tank is diverted into the absorber.

4. Watch the liquid level of the refrigerant tank. Im-mediately after the refrigerant liquid level appears in the level gauge of the refrigerant tank, close the valve (turn it to the right until it stops).

5. Press the Refrigerant Pump Stop button. The re-frigerant pump stops.

6. Let the solution pump operate independently for 30 minutes.

7. Press the Forced Dilution OFF button to stop the solution pump.

8. Press the Refrigerant Pump Auto button.


JOHNSON CONTROLS 89


7

DECRYSTALLIZATION METHODEven if the solution in the absorption heat-pump is crystallized during operation, it can be melted if the crystallization is not severe. Since it becomes more dif-ficult to melt the crystals as time passes, perform the following operation immediately when crystallization is detected. If the crystals cannot be melted using the following procedure, notify your local Johnson Con-trols Service Center immediately.

Indications of Crystallization1. The heating capacity goes down, the liquid level

in the absorber drops, and cavitation noise comes out of the solution pump.

2. The Solution Circulation Pump Abnormal or the Solution Spray Pump Abnormal button lights and the solution pump trips.

3. The liquid level in the absorber is low. The solu-tion seen through the generator level gauge (G4) is white.

4. The liquid level in the absorber drops and the tem-perature of the solution returning from the genera-tor goes down.

Decrystallization1. Stop the absorption heat-pump. If the solution

pump tripped, reset the thermal relay.

2. Disconnect the electrical wiring of the solution pump.

3. Press the Forced Dilution ON button.

Since the electrical wiring of the solution pump is disconnected, only the refrigerant pump starts.

4. Remove the cap of the refrigerant manual blowdown valve VR1.


5. Turn the spindle in the valve to the left with the 8 mm hexagon wrench.

The refrigerant in the refrigerant tank diverts into the absorber.

6. Watch the liquid level of the refrigerant tank.

7. Immediately after the refrigerant liquid level ap-pears in the level gauge of the refrigerant tank, close the refrigerant manual blow-down valve (turn it to the right until it stops).

8. Press the Refrigerant Pump Stop button. The re-frigerant pump stops.

9. Press the Forced Dilution OFF button

10. Re-connect the electrical wiring of the solution pump.

11. Press the Forced Dilution ON button. The solu-tion pump starts.

12. Navigate to the Control screen.

13. Press the steam control valve or steam drain con-trol valve Manual button.

14. Set the Manual Input on the Control1 screen to 30 to 40%. Constantly observe the liquid level in the absorber during this period

15. When the liquid level in the absorber drops, stop the supply of steam and press the Forced Dilution OFF button.

16. Repeat steps 12 through 16 three - four times. If the liquid level in the absorber does not go down, the crystals have melted.

JOHNSON CONTROLS90


17. Stop the steam supply.

18. Let the solution pump operate independently for about 30 minutes. Constantly observe the liquid level in the absorber while the solution pump op-erates.

19. After about 30 minutes, stop the solution pump.

20. Press the refrigerant pumps Auto button


Precautions for Decrystallization1. Cycle the heat source and hot water pumps off and

on during the melting process.

2. Remove any sensors that are sensitive to heat be-fore you start the melting operation. The tempera-ture of the heat source and hot water that remains in the absorption heat-pump may rise to about 70°C.

3. When you start the heat pump after melting the crystals, discharge the heat source water and hot water first. If that water is left in the machine, the paint on the inside walls may be peeled off.

WATER QUALITY CONTROLUse the following guidelines to be sure of the highest water quality control standards:

1. Limit the water pressure to the maximum safe working pressure for heat source and hot water.

2. Install a 10 or finer mesh strainer in the heat source and hot water piping.

3. Install a thermometer and a pressure gauge in the inlet and the outlet of the heat source and hot wa-ter piping.

4. Install tapping (with valve) for chemical cleaning of the inlet and the outlet of the heat source and hot water piping.

5. Install an air vent valve at the highest part of the piping and a drain valve at the lowest part of the piping.

6. Replace the water regularly and control the water quality. Operating the heat pump for long periods of time with low quality water will cause corro-sion and the production of scale.

7. Close the main steam supply valve during an ex-tended shut down.

8. Make sure the shut off valves installed at the heat

TABLE 19 - LIFESPAN OF COMMON PARTS (CONT'D)

6. pump inlet of the heat source water and hot water are completely open.

If the heat pump runs without the valves completely open, a strong turbulent flow can be generated. The turbulence may cause damage in the water chamber case and the copper tube of the heat pump. If you need to adjust the flow rate of the heat source water and the hot water, be sure to adjust the valves installed at the outlet side of the heat pump.

7. Install a safety valve on the steam line.

8. Install an expansion tank on the hot water line if the hot water is a closed system.

JOHNSON CONTROLS96


CHEMICAL WATER TREATMENTSince the mineral content of the water circulated through the evaporator, condenser, absorber, and gen-erator varies, the water being used may corrode the tubes or deposit heat resistant scale in them.

Perform a chemical analysis of the water before the system is installed. Consult a reliable water treatment company to determine if treatment is necessary. If it is, the company can provide treatment for the water to help prevent damage to the tubes.

REPLACEMENT OF WATERIf the heat source water line or the hot water line are open systems, they must be cleaned or replaced peri-odically. If the water is not treated at all in the water line, the recommended intervals for replacement of both types of water are:

District polluted with sulfurous acid gas --- 5 days

Common district --- 10 days

If the water is blown manually or automatically, the replacement period may be lengthened as follows.

District polluted with sulfurous acid gas --- 1 month

Common district --- 1 month

TREATMENT FOR LONG STOPPAGE OF THE ABSORPTION HEAT-PUMPIf the absorption heat-pump is stopped for a long time, bacteria in the water or in the tubes may grow. The bacteria can corrode the tubes. When stopping the heat pump for more than 15 days, drain the water from the absorber, condenser, evaporator, and generator through the drain valve at the bottom of the waterbox.

CHEMICAL TREATMENTCorrosion inhibitors are attracted chemically to corrod-ed metal surfaces. Or, they form inert protective com-pounds over the metal surfaces. For effective use of the corrosion inhibitors, be sure to choose the correct type and concentration. Water quality, temperature, flow speed, metals used, existence of crevices and deposits and type of water system are also part of the equation. For more information about corrosion preventive mea-sures, consult a water treatment company.

FLOW SPEED IN TUBESSince the water flow speed in the tubes is closely re-lated to any existing corrosion, do not increase the wa-ter supply rate more than recommended. If the flow speed reaches 3.5 to 4 meters per second, the tubes may erode. When changing the flow rate, contact your local Johnson Controls Service Center.

If the water supply rate is adjusted at the inlet side of the heat exchanger (evaporator, condenser, and absorb-er), the eddy current at the inlet may corrode the tube.

Accordingly, be sure to control the flow rate on the out-let side.

The eddy current caused by foreign matter in the heat exchanger is also a factor in corrosion. Be sure to in-stall a strainer on the inlet side of the heat exchanger and clean the strainer periodically.

STORAGE METHOD OF THE HEAT PUMPIf the heat pump needs to be stored long-term, the stor-age method varies. A lot depends on the machine room temperature condition and the storage period. If the machine room temperature is below 0°C, drain off the heat source water, hot water, and the steam drain. Dry the tube interiors. Make sure all equipment installed in the heat source water, hot water, and the steam lines is completely dry.

Nitrogen gas pressurization inside the absorption heat-pump is required when the storage period exceeds 6 months. Contact your local Johnson Controls Service Center for more details.

The heat pump is not explosion proof. Highly flammable items, gas, or liquids should not be handled or stored near the heat pump. Failure to do this may result in explosion, injury, or damage to the equipment or building.

There are two storage methods available for the heat pump during off-season (winter) or plant suspension; the wet storage method and the dry storage method. (The wet storage method is available only where heat source water and hot water will not freeze.)

Each storage method has its own characteristics. Select the method to use based on the plant’s features and the storage period. Details follow.

WET STORAGE METHODThe wet storage method may be used when there is no concern about heat source water or hot water freezing in winter. Store the machine in a place where the ambi-ent temperature will remain higher than 0°C.

If it is likely that the temperature will drop below that, provide a heater for the machine. If a heater is not pos-sible, contact your local Johnson Controls service cen-ter for further information. For details on the wet stor-age method, see Table 28 on page 102.

The wet storage procedure is as follows if either the heat source water line or the hot water line is an open system:

1. Completely drain the water from the systems if it has deteriorated in quality.

2. Clean the water systems by passing clear water through them from a position higher than the heat pump.

9. Fill the water systems with clear water.

10. Circulate the clear water through the water pump for 30 minutes to one hour to clean it.

11. Drain the water.

12. Completely fill the water systems with clear water again.

13. Store the machine.

DRY STORAGE METHODThe dry storage method should be used if the heat source or hot water system may freeze in the winter or, if the heat source or hot water system has a lining tube. Do not simply drain the heat source or hot water and store the machine. This significantly increases the pos-sibility of corrosion of the heat transfer tube and rust. For details, see Table 29 on page 103.

The dry storage procedure is as follows if either the heat source water line or the hot water line is an open system:

1. Completely drain the water.

2. Clean the water systems by passing clear water through them from a position higher than the heat pump.

3. Fill the water systems with clear water.

4. Circulate the clear water through the water pump for 30 minutes to one hour to clean it.

5. Drain the water from each water or steam box.

6. Dry the interior of each water or steam box and the heat transfer tube.

7. Store the machine.

JOHNSON CONTROLS102


PRECAUTIONS AGAINST EXTERNAL DAMAGEAvoid storing the machine in a place that is easily ac-cessible or near a construction site. If this is unavoid-able, provide the machine with protection.

If it is not possible to protect the machine, fill the in-terior with N2 to minimize the amount of air leakage. For details, contact your local Johnson Controls ser-vice center.

1. The manual valve on the purge piping should be completely closed (See Figure 43 on page 83.

2. The main supply valve supplying steam must be closed.

3. If the storage period exceeds 2 months, to avoid the growth of algae and bacteria that may corrode the tubes, add the appropriate chemicals to the water.

4. If the storage period exceeds 2 month, water inside the heat pump should be replaced monthly. In addi-tion, run the heat source water and hot water pumps periodically.

5. If the storage period exceeds 6 months, check the internal nitrogen pressure weekly. It needs to stay at 0.01~0.02 MPaG.

drained completely and dried by nitrogen blow. Then pressurize with nitrogen and leave as is. Depend-ing on the water quality, hard scale may be fixed on the inside surface of tubes by drying. It can be removed only by chemical cleaning. If the unit is be stored for more than one year, you must clean the tubes. Then, drain the unit, dry the inside by nitrogen blow,and pressurize it with nitrogen.

2. The main supply valve supplying steam must be closed.

3. If the storage period is longer than 6 months, apply pressure at 0.01~0.02 MPaG with nitrogen inside the shells and leave as is. Internal pressure should be checked at least once a week to confirm no pres-sure drop occurs.

4. The manual valve on the purge piping should be fully closed (See Figure 43 on page 83).

SECTION 8 – TROUBLESHOOTING

If the heat pump has a problem or an abnormal condi-tion while it operates, find the cause. Use the proce-dures listed below to fix the problem.

If the cause is not clear, using the countermeasure does not fix the problem, or if the heat pump seems to have a serious problem, contact your local Johnson Controls Service Center immediately.

If the heat pump stops because of a problem, wait until the heat source water pump, hot water pump, and heat pump unit stop completely, then review and verify the following items.

Several items should be checked routinely whenever the heat pump experiences any trouble or abnormality:

• Check to see if the main steam valve was closed by mistake.

• Open the main valve.

• See if the valves of the heat source water system and the hot water system are set correctly. Verify the flow rate.

Contact your local Johnson Controls Service Center if any of the following apply:

• The water flow rate setting is unknown.

• It takes 30 minutes or more to restore operations.

• Solution is crystallized.

• The cause of the trouble is not readily apparent.

Check the causes in order. Any of these causes will start the diluting operation automatically then stop the heat pump. Check that the diluting operation was completed, and if not, dilute the solution. See the Manual Refrigerant Blowdown and Diluting Method on page 88 .

TABLE 30 - GENERATOR HIGH TEMPERATURE, GENERATOR HIGH PRESSUREITEM CAUSE COUNTERMEASURE

1 Hot water flow is low or flow has stopped.

• Check the flow meter, discharge pressure of the hot water pump, current, etc. • If the flow rate is low, check the opening ratio of the flow control valve.• Check to see if the strainer is clogged.

2Pressure or flow rate of steam exceeds the specification value

• Check and change, if necessary, the boiler's pressure setting point so that it matches the specification.

• Check and adjust the back pressure of the steam drain line during operation under the condition close to the specification, so that it matches the specification.

2 Non-condensable gas stays in the machine.

• Check the capacity of the vacuum pump. • Check the purge unit.• Purge non-condensable gas from the heat pump (See Purge Procedure on page

81). • If partial load operation is continued for a long period, non-condensable gas tends

to stay in the absorber. In this case, purge directly from the low pressure side (according to instructions in Purge Procedure on page 81.

4Heat exchange tube is dirty (heat source water, hot water).

Contact your local Johnson Controls Service Office. 5 Solution is crystallized.6 Corrosion inhibitor is worn.

7 Air leaks in absorption heat pump.

TABLE 31 - REFRIGERANT OVERCOOLED, SOURCE WATER OVERCOOLED

When the refrigerant or the heat source water is over-cooled, the heat pump stops immediately. It does NOT perform the dilution operation. When this happens, the solution may crystallize in 4-5 hours. Perform the Manual Refrigerant Blowdown and Diluting Method on page 88.

ITEM CAUSE COUNTERMEASURE

1Heat source water flow rate drops or changes drastically.

See if the heat source water flow rate changes drastically (particularly in the case of variable flow rate specification). If it changes, limit the change rate to the heat source water flow control or take another measure.

2Load of heat source water side drops too far or too quickly.

See if the load of the heat source water side changes drastically.

3 Refrigerant is dirty (contains solution).

See if the refrigerant refining operation has been performed periodically. For the refrigerant refining method, see the procedure shown Refrigerant Refining Method on page 88.

4 Heat exchange tube is dirty (Heat source water)

Contact your local Johnson Controls Service Office.5 Temperature controller is

broken.

JOHNSON CONTROLS110


TABLE 32 - SOURCE WATER SUSPENSION

When heat source water flow stops, the absorption heat pump also stops immediately. It does NOT perform the dilution operation. If the absorption heat pump is left as it is, the solution in it may be crystallized in 4-5 hours. To prevent this, dilute the solution according to manual refrigerant blowing and diluting method. See Manual Refrigerant Blowdown and Diluting Method on page 88 for more information.


1 Heat source water pump has a problem.

Check the heat source water pump for a problem.

2 Heat source water flow rate is low.

• Check to see if the heat source water flow rate is below the set point of the water suspension switch.

• If it is low, check the flow controller, check the strainer for clogging, and check the opening ratio of the flow control valve.

3Pressure transfer pipe of water suspension switch is clogged. Contact your local Johnson Controls Service Office.

4 Water suspension switch is broken.

TABLE 33 - PUMPS ABNORMAL

If the heat pump has a pump problem, it stops imme-diately and does NOT perform the dilution operation. If left as it is, the solution in it may be crystallized in 4-5 hours. To prevent this, contact your local Johnson Controls Service Office immediately.

ITEM CAUSE COUNTERMEASURE1 Bearings of the pump are worn or clogged.

Contact your local Johnson Controls Service Office.

2 Pump is damaged by cavitation caused by low liquid level.3 Thermal switch is not set properly.4 Internal cycle control valve is not set properly.5 Filter in the pump is clogged.6 Solution is crystallized.7 Circuit breaker has tripped.8 Inverter has a problem (Inverter equipped model only)

TROUBLESHOOTING PERFORMANCE ISSUESIf the performance is low while the steam control valve is open or if the steam control valve does not com-pletely open while the load is sufficient, check num-bers 1-7 in the following table in order. If the cause of the trouble is not 1-7, it may be 8-14. If that is the case, contact your local Johnson Controls Service Cen-ter immediately.

TABLE 34 - TROUBLESHOOTING PERFORMANCE ISSUES


1 Pressure or flow rate of steam is below specifications

• Check and change the boiler's pressure set point so that it matches the specification.

• Check and adjust the back pressure of the steam drain line during operation so that it matches the specification.

2 Hot water flow rate is low.

• See if the hot water supply rate matches the specification. (Check the flow meter, discharge pressure of the hot water pump, current, etc.)

• If the flow rate is low, check the opening ratio of the flow controller valve and check the strainer for clogging.

3 Hot water heat exchange tube is dirty. Contact your local Johnson Controls Service Office.

4 Non-condensable gas remains in machine.

• See Purge Procedure on page 81. • Check the capacity of the vacuum pump. • Check the purge unit for trouble. • Purge non-condensable gas from the absorption heat pump. If

partial-load operation continues for a long time, non-condensable gas tends to stay in the absorber. In this case, purge directly from the low-pressure side (absorber). See Purge Procedure on page 81.

• Even if the automatic purge unit is installed, purge from the lower pressure side (absorber) manually.

5 Temperature controllers are not set properlyBe sure that each setting parameter for temperature control is set correctly.

6 Manual refrigerant blow valves are kept open. Check that the manual refrigerant blow valve VR1 is closed.7 Refrigerant Pump Stop button is lit. Press the Refrigerant Pump Auto button.8 Corrosion inhibitor is depleted.

Contact your local Johnson Controls Service Office.
