19. Low Ambient Cooling Enhancement
RELQ72-240TATJA / TAYDA / TAYCA
RELQ-T series include a feature for Low Ambient Cooling. The function enhances RELQ-T series as follows:
• Allowsoperationto−4°FDB(−20°CDB)ambienttemperatureincoolingmode.(Normallimitis23°FDB(−5°CDB).)• Operationbelow23°FDB(−5°CDB)requirestheadditionofwindcoversontotheoutdoorunit.*
Application Rules: • Total connection index of each system is limited to 50-130% when height difference is 0-194 ft. (0-50 m), 80-130% when 194-
295 ft. (50-90 m).• All units on the system must be connected to a Branch Selector Box, Low ambient cooling is only available on indoor unit
connected to a single branch selector box. Single and Multi-port Branch Selector Boxes may be combined on one system but all indoor units connected to a multi branch selector box will operate as standard without the low ambient cooling function.
• Functionisengagedbyafieldsettingontheoutdoorunit(toenableLowAmbientCooling)andadipswitchsettingisnecessaryonthe Single Branch Selector Boxes BSQ-T series serving the indoor units NOT subject to Low Ambient Cooling requirements.
• Duringoperationbelow23°FDB(−5°CDB),theavailablecoolingcapacitydecreasesasfollows: 14°FDB(−10°CDB)-Reducesto80%ofnominal. 5°FDB(−15°CDB)-Reducesto65%ofnominal. −4°FDB(−20°CDB)-Reducesto60%ofnominal.(OnlyapplicabletoSingle-portBranchSelectorBoxes)
• The operating sound level of the Single Branch Selector Boxes BSQ-T series could increase 3 dB(A) higher than maximum while the system is operating in the Low Ambient Cooling mode. It is recommended to locate units away from zones sensitive to sound levels.
• Allowable height difference between outdoor and indoor units (when outdoor unit is below) is limited to 130 ft. (40 m). (Normal limit is 195 ft. (60 m).) * Contact your local Daikin representative for wind cover specification requirements and part numbers.

22. Selection Procedure22.1 Selection Procedure22.1.1 Flowchart
Provisionally select outdoor unit type and size based on limitation of connection ratio
Correct for cooling & heating capacity of the outdoor unit by the following items
VRV system selection is complete.
Confirm that the number of indoor units connected to the outdoor unit is within limitation.
Corrected capacity of the outdoor unit ≥ Required total heat load to the outdoor unit
2) Use the system peak load1) Use the sum of the peak load of each room
Define required total heat load to outdoor unit
Indoor unit capacity corrected for indoor air temperature (WB) ≥ Required heat load × Safety factor for the indoor units
Yes
No
-Piping length, level difference-Piping heat loss-Safety factor for the outdoor unit-Defrost (only for heating capacity)
-Outdoor air temperature-Indoor air temperature-Connection ratio
Given conditions:· Design temperature and humidity (indoor & outdoor)· Required heat load of each room· System peak load (if necessary)· Piping length, level difference· Specifications of indoor units (type and number)
Define safety factor for the indoor units and outdoor unit

* In case of selection based on Total Heat Load and Sensible Heat Load, select indoor units which satisfy not only the Total Heat Load but also the Sensible Heat Load of each room. The sensible heat capacity of indoor units is to be corrected for indoor air temperature. If the design temperature of indoor air falls between temperatures listed in table, calculate sensible heat capacity by using the bypass factor calculated by interpolation for each indoor air temperature.

24. Caution for Refrigerant Leaks24.1 Introduction
The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following standards may be applicable if local regulations are not available.
The VRV System, like other air conditioning systems, uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible refrigerant.Neverthelesscaremustbetakentoensurethatairconditioningfacilitiesareinstalledinaroomwhichissufficientlylarge.Thisassuresthat the maximum concentration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to the local applicable regulations and standards.
Maximum concentration levelThe maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak.The unit of measurement of the concentration is lbs./ft.3 (kg/m3) (the weight in Ibs. (kg) of the refrigerant gas in 1 ft.3 (1 m3) volume of the occupied space).Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.
Direction of therefrigerant flow
Room where refrigerant leak has occurred(outflow of all the refrigerant from the system)
Pay special attention to places, such as basements, etc. where refrigerant could stay, since refrigerant is heavier than air.
72
RELQ-TATJA / TAYDA / TAYCA EDUS371705C-D
24.2 Procedure for Checking Maximum Concentration
Check the maximum concentration level in accordance with steps 1 to 4 below and take whatever action is necessary to comply.Step1: Calculate the amount of refrigerant (lbs. (kg)) charged to each system separately.
Amount of refrigerant in a single unitsystem (amount of refrigerant withwhich the system is charged beforeleaving the factory)
+
Additional charging amount (amountof refrigerant added locally inaccordance with the length or diameterof the refrigerant piping)
= Total amount of refrigerant (lbs. (kg))in the system
Note:Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then use the amount of refrigerant with which each separate system is charged.
Step 2: Calculate the smallest room volume (ft.3(m3)) In case like the following, calculate the volume of (a), (b) as a single room or as the smallest room. (a) Where there are no smaller room divisions.
(b)Wherethereisaroomdivisionbutthereisanopeningbetweentheroomssufficientlylargetopermitafreeflowofairbackandforth.
Opening betweenrooms
Partition
(Where there is an opening without a door or where there are openings above and below the door which are each equivalent in size to 0.15% ormoreofthefloorarea.)
(c) Where there is a gas leak detection alarm device linked to a mechanical ventilator in the smallest room then the next smallest room will become the measurement target.
73
RELQ-TATJA / TAYDA / TAYCA EDUS371705C-D
Step 3: Calculating the refrigerant density using the results of the calculations in steps 1 and 2 above.
Total volume of refrigerant in therefrigerant system
≤ Maximum concentration level (lbs./ft.3(kg/m3))Size (ft.3(m3)) of the smallest room in whichthere is an indoor unit installed
If the result of the above calculation exceeds the maximum concentration level then make similar calculations for the second then third smallest room and so until the result falls short of the maximum concentration.
Step 4: Dealing with the situations where the result exceeds the maximum concentration level. Where the installation of a facility results in a concentration in excess of the maximum concentration level then it will be necessary to revise
the system. Please consult your Daikin supplier.
