5. Capacity Range
5.1 Connection Ratio
Both indoor and outdoor units have a capacity index number and the connection ratio is defined as the ratio of these two numbers.
Connection ratio =
Total sum of indoor unit capacity index Outdoor unit capacity index number
Example: � 2 � CXTQ36 connected to 1 � RXSQ60T = 72 / 57 = 1.26 � Therefore the connection ratio = 126%

17.1.2 Selection Example 1 - CXTQ & VRV Indoor Units
The following is a selection example for a VRV LIFE system incorporating a CXTQ & gas furnace and other VRV indoor units.
[1] Given conditions -System arrangement � The home will use a CXTQ & gas furnace as a Central Zone to supply air to most of the home. � There is a Bonus Room upstairs that has historically been uncomfortable. This room will use an FXEQ one-way-blow cassette to give independent
temperature control to the room. � The outdoor unit will be located on the ground level. � The CXTQ & gas furnace will be installed in the basement, 10 ft. below ground level. � The FXEQ will be installed in the Bonus Room upstairs 18 ft. above ground level. � The equivalent piping length for the system is 45 feet.
-Design conditions � Indoor air temperature -- cooling: 77�FDB / 64�FWB � Indoor air temperature -- heating: 70�FDB � Outdoor ambient air temperature for cooling: 95�FDB � Outdoor ambient air temperature for heating operation: 13�FDB / 7�FWB
-Determine the required cooling and heating capacities using an industry accepted load calculation method (i.e. ACCA Manual J or similar).

-Safety factor For this example, no safety factor will be used. (i.e. safety factor = 1.0)
[2] Selection of indoor unit(s) and gas furnace(s) To select the CXTQ & gas furnace: � Determine the corrected total cooling capacity of the CXTQ at the defined indoor air temperature by referencing the capacity table in the CXTQ
Engineering Data manual. � If the design indoor air temperature falls between temperatures listed in the capacity table, calculate the capacity by interpolation. � The corrected total cooling capacity should meet the required cooling load of the zone. � The selected gas furnace should have a High Fire output that meets or exceeds the required heating load of the zone. � The selected gas furnace should also be confirmed to be a compatible furnace combination with the selected CXTQ. Refer to the CXTQ
Engineering Data manual.
To select the VRV indoor unit: � Determine the corrected cooling capacity and the corrected heating capacity of the unit at the defined indoor air temperatures by referencing the
capacity table in the indoor unit's Engineering Data manual. � If the design indoor air temperature falls between temperatures listed in the capacity table, calculate the capacity by interpolation. � The selected indoor unit's corrected cooling capacity and corrected heating capacity should meet or exceed the zone's cooling and heating loads,
respectively.

Selection results of indoor units: � Required cooling capacity for Central Zone = 42,350 Btu/h CXTQ48TASBLU � Required gas furnace capacity for Central Zone = 95,000 Btu/h DM97MC1005CNA
� Required cooling capacity for Bonus Room = 8,000 Btu/h
FXEQ09PVJU
� Required heat pump heating capacity for Bonus Room = 10,000 Btu/h
In the case of a selection based on Total Cooling Load and Sensible Cooling Load, select the indoor unit(s) which will satisfy not only the Total Cooling Load (TC) but also the Sensible Cooling Load (SHC) of each zone. The sensible capacity of the unit should also be corrected for indoor air temperature.
[3] Selection of outdoor unit [3] �1 Define the total cooling and heating load from the indoor units to the outdoor unit Define the total required cooling load (A) and heating load (B) for the system according to: � (1a) Sum total of cooling loads for all zones � (1b) Sum total of heat pump heating loads for all zones
Or � (2a) Total system cooling load � (2b) Total system heat pump heating load
Note: Using the sum-total load approach results in selecting an outdoor unit that will provide full capacity to all zones simultaneously. This approach is more conservative but may result in an oversized unit, depending on the actual diversity of the cooling and heating loads in each zone.
Using the Total-system approach allows the outdoor unit size to be optimized to meet the total system load. For example, it is assumed the Bonus Room will not require full capacity at the same time the Central Zone is requiring full capacity. The VRV LIFE system can manage refrigerant flow to each CXTQ and/or VRV indoor unit to independently control the capacity of each unit.
When selecting the VRV LIFE outdoor unit for heating capacity, typically only the spaces served by VRV indoor units are considered. Zones served by a gas furnace will not require heat pump heating on the coldest days of the year, so the VRV LIFE outdoor unit should be selected to ensure that heat pump heating can be provided to the VRV indoor units.
In this example, select an outdoor unit using method (2a/2b). It is assumed that the total home cooling and heating loads have been calculated as: (A) = (2a) = 48,250 Btu/h cooling load (B) = (2b) = 10,000 Btu/h heat pump heating load

(3) Confirm that the number of connected indoor units is within the limitation. The CXTQ should be treated as an indoor unit for purposes of counting the total number of indoor units. � The number of connected indoor units = 2 � The maximum number of connectable indoor units to the 4-ton unit = 8
[3] -3 Calculate the corrected capacity of the outdoor unit. Calculate the connection ratio of the system. The connection ratio is the ratio of indoor unit capacity to outdoor unit capacity. � Total CI of indoor units = 57.5 � CI of RXSQ48TAVJUA = 48 � Connection ratio = 57.5 / 48 = 120%
Using the capacity table of the outdoor unit, determine the corrected outdoor unit capacity using the outside ambient temperature, indoor air temperature, and connection ratio.
When calculating the heat pump heating capacity of the system, it is important to consider the gas furnace use. Typically the gas furnace will be providing the heating capacity to the zone served by the CXTQ & gas furnace, therefore it is only necessary to ensure the outdoor unit can provide the heat pump heating capacity required for only the VRV indoor units at the design outside ambient air temperature.
Note: In the case that the outdoor temperature, indoor temperature, or connection ratio falls between the temperatures or connection ratios listed in the tables, calculate the capacity by interpolation.

RXSQ-TAVJUAEDUS331721A-D
RXSQ48TAVJUA Heating Capacity In this example, heat pump heating is only required for the FXEQ09PVJU at the 13�F. The gas furnace will handle the heating capacity for the zone served by the CXTQ. Determine the capacity available to VRV indoor units by considering the connection ratio of the VRV indoor unit capacity index vs. VRV outdoor unit capacity index. If the ratio is less than 50%, assume a 50% connection ratio for reference.
Determine the cooling and capacity correction factor from the refrigerant piping length and vertical piping differences. Heating capacity is not affected by refrigerant piping lengths. � Cooling capacity correction factor calculation
System equivalent piping length: 45 feet Piping vertical height separation: 18 feet from outdoor unit

CC = Cooling capacity from capacity table = 48.9 MBH a = Cooling capacity correction factor = 0.978
Corrected cooling capacity = CC � a = 48.9 MBH � 0.978 = 47.82 MBH
Determine the heating capacity correction factor for frost building during heating operation.
Inlet air temperature to the outdoor unit heat exchanger (�FDB/RH85%) Correction factor for frost accumulation

In this example, the design ambient condition for heat pump heating operation is 13�FDB, so defrost correction factor for frost accumulation is 0.95.
HH = Heating capacity from capacity table = 26.0 MBH b = Defrost correction factor for frost accumulation = 0.95
Corrected heating capacity = HH � b = 26.0 MBH � 0.95 = 24.7 MBH
[4] Select an auxiliary heat source, if necessary For VRV LIFE systems designed to operate in extreme cold climates (lower than �4�F, the minimum heat pump operating range for VRV LIFE) by running the gas furnace, it may be necessary to select a third part auxiliary heat source to provide heating capacity to zones served only by VRV indoor units.
In this example, the winter design ambient temperature condition is 13�F and the heat pump heating capacity of the VRV LIFE system can provide enough heating capacity to the Bonus Room, so there is no need to select any auxiliary heat source.

19.Caution for Refrigerant Leaks
19.1 Introduction
Points to note in connection with refrigerant leaks 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. Nevertheless care must be taken to ensure that air conditioning facilities are installed in a room which is sufficiently large. This assures that 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 level The 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 lb./1000 ft.3 (the weight in Ibs. of the refrigerant gas in 1 ft.3 volume of the occupied space). Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.
Direction of the refrigerant 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 can stay, since refrigerant is heavier than air.
61
RXSQ-TAVJUAEDUS331721A-D
19.2 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.) charged to each system separately.
Amount of refrigerant in a single unit system (amount of refrigerant with which the system is charged before leaving the factory)
Additional charging amount (amount
+
of refrigerant added locally in accordance with the length or diameter
=
Total amount of refrigerant (lbs.) in the system
of the refrigerant piping)
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) 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) Where there is a room division but there is an opening between the rooms sufficiently large to permit a free flow of air back and forth.
Opening between
rooms
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% or more of the floor area.)
(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.
62
RXSQ-TAVJUAEDUS331721A-D
Step 3: Calculating the refrigerant density using the results of the calculations in steps 1 and 2 above.
Total volume of refrigerant in the
refrigerant system
Maximum concentration level (lbs./ft.3)
Size (ft.3) of the smallest room in which
there 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.
