Features and Benefits
VRV Heat Pumps are a highly efficient method of conditioning a space. Daikin invented the technology in 1982. Refrigerant matched precisely with the load, rather than water or air, is used to transfer heat within the room.
» Simplified Installation: A simple modular design allows for quick and easy installation often within a day’s work.
» Scalable Design: The modular design of VRV systems allows for the flexibility of simplified future expansion.
» Quiet Operation: Standard low operating sound levels for undisturbed home comfort.
» Year Round Comfort: Wide range of operation with heat pump heating down to -4º F, connection of gas furnace for colder climates, and cooling up to 122º F.
» Individual Comfort: Personal comfort control in each room or zone. » Total Zone Control: Cool or heat only the rooms needing indoor comfort.
» Daikin residential (RXSQ) VRV LIFE™ systems are AHRI certified in accordance with Standard 210/240 for unitary air-conditioning and air source heat pump equipment.

Inverter Driven Compressors
The inverter driven compressor is the heart of Daikin’s VRV system to help maximize energy savings. Daikin’s inverter technology is responsible for delivering intelligent comfort, at a variable capacity, with efficiency, based on demand.
Variable Capacity OutputDaikin’s inverter driven compressors will only provide the required amount of refrigerant needed to meet the capacity demand. Daikin inverter technology helps systems run at an energy-conserving level, despite the climate conditions, by making slight adjustments to the compressor’s speed. Daikin inverter systems will reach the desired temperature faster and maintain a more constant temperature compared to traditional
ON/OFF systems. It will not frequently start and stop the “old fashioned way” just as a car is more efficient and comfortable traveling on a highway than it is in stop-and-go city traffic.
Less Energy ConsumptionWith an inverter driven compressor, average energy savings of 30% are easily obtainable, when compared to traditional DX systems.
Efficient Part Load PerformanceDaikin’s inverter driven VRV system operates most efficiently in part load conditions. A VRV LIFE™ system will operate most of the time at part load conditions. (A typical VRV system will run 3/4 of its operating hours at less than 70% of full capacity.)

Refrigerant Piping InsulationIt is recommended that both the liquid and gas refrigerant lines are insulated. Liquid line insulation is imperative in the following situations:
» If it is intended to operate the system at reverse ambient temperatures (ex. Cooling: outdoor temp<indoor temp).
» If the ODU(s) is above the IDU(s) In applications with existing liquid main line sets, insulation may be excluded provided the conditions above do not apply.
» However accessible portions and portions located outside must be insulated.
A field setting is required based on gas pipe size and liquid line insulation (See installation manual). Factory Default Setting:
– Gas Pipe = >standard – Liquid pipe = insulated

WebXpress Residential VRV Selection Tool
Residential WebXpress is a web based VRV LIFE™ system selection tool allowing for the automatic sizing of the primary components of a VRV LIFE system.
Obtain Project DataBefore selection of any system, a minimum amount of information is required for accurate equipment selection and to apply an optimized design.
For an accurate selection of IDUs the following information is required.
» Peak Cooling & Heating Loads: The maximum total and sensible loads (total only for heating) required to condition the space
– Obtained via Manual J calculations – Possible to select for cooling with only total or sensible
» Design Air Conditions: The dry and wet bulb temperature entering the IDU (Dry bulb only for heating).
– The wet bulb can also be specified as a relative humidity – Typical Cooling: 75°F db, 50% RH (63°F wb) – Typical Heating: 70°F db
21
For an accurate selection of ODUs the following information is required
» Ambient Conditions: the design ambient conditions for the location of the project
– If this information is not at hand then use ASHRAE standard design conditions
– Ex. ASHRAE conditions for Rochester, NY › Winter: 1°F db › Summer: 89°F db, 73°F wb
– Gas Furnace Heating condition will typically be the same as heat pump heating condition unless the design heating load obtained occurs below -4°F
SYSTEM SELECTIO

Daikin compatible gas furnace paired with a VRV A-Coil (up-flow & down-flow)
» The A-Coil (CXTQ) is powered by the gas furnace via a factory supplied 24V transformer
» The gas furnace is controlled by the CXTQ over ClimateTalk (4’, 24 VDC, 4-wire factory supplied communication cable)
» Critical Gas Furnace error codes are transmitted & displayed on controller (Minor errors indicated as error code AA)
» The A-coil may be installed in a draw through configuration (suction side of the furnace).
– A P-trap on the condensate line is necessary in draw through applications to prevent air from being drawn back through the line

ControlsWireless Controller
A wireless controller is available for use with IDU. Wireless controllers are often used in bedrooms or zones that do not see frequent multiple occupants.
Remote Temperature Sensors:Most applications do not require the use of a remote temperature sensor. Typically an IDU will use an internal return air temperature sensor or the sensor on the navigation remote control for feedback to condition the space.
However, there are applications in which the unit may not have a return air sensor and/or the navigation control location is not ideal for temperature sensing. These applications require the use of a remote temperature sensor.
Note: The FXTQ and the CXTQ must use the navigation control or a remote temperature sensor (KRCS01-2UA) as they do not have a return air sensor within the unit

Installation Considerations
Snow ExposureWhen installing the ODU in a location frequently exposed to snow consider the following:
» Elevate the foundation as high as possible
» Attach a snow hood (field supplied)
» Remove the rear inlet grille to prevent snow from accumulating on the rear fins
Strong Wind ExposureStrong winds (≥11 mph) may force recirculation of exhaust air into the inlet resulting in a deterioration of the system performance and possible increased frost formation in heating mode. Consider wind effects when placing the outdoor unit and using a wind baffle.

Receiver Tank Kit InstallationA receiver (liquid refrigerant tank) is required in applications where the RXSQ is connected to both a gas furnace and other VRV IDUs.
The receiver kit (BHL-02A) ships from the factory in a sheet metal enclosures. The refrigerant tank is independent of refrigerant flow direction. Either one of the 3/8” connections can be connected to the liquid connection on the ODU.
Adhere to the following installation guidelines:
» Install the tank in the nearest and most convenient location to the ODU near the liquid service valve. The tank can be oriented to the front, rear, or side of the ODU.
» Refer to the ODU installation manual for clearance and service space around the ODU.
» If necessary use fasteners on the base.
» There is no specific required distance between ODU and the tank.

MasterUnit
There are four ways to provide heat/cool changeover on a VRV LIFE™ system.
Master UnitThe simplest way to address heat/cool changeover automatically is to nominate a master unit. When the unit’s return air sensor measures outside the temperature set point limitation, the unit switches itself and all other units on the system to the different mode.
Master ControllerSimilar to the previous option except mode selection is made manually by a designated master controller. Again, all other units on the system will switch mode in unison.
Note: A common pitfall is to elect an area that is not in constant use or has no easy access to all occupants (bedroom). In both applications above, if the unit isn’t running then mode change is not possible without manual intervention.
54
Heat Pump Changeover
AmbientSensor
AUTO CHANGEOVERvia Master Unit
MANUAL CHANGEOVER
Summer/Winter SwitchA Daikin supplied switch is attached to “ABC” terminals on the outdoor unit to allow manual change over from a central location. This is common in applications that usually require year round cooling.
3rd Party Ambient SensorThis option was developed to provide an automatic version of summer/winter switch previously described. A remote ambient sensor will dictate when mode change occurs. Although possible, it is an option rarely seen on residential applications.
Summary: With ALL changeover options, when a system mode is changed, the indoor units on the system are not forced into heating or cooling. If there is no demand in the room for the mode that has been selected, the unit(s) will run in fan only mode.

Heating Requirement
VRV LIFE™ systems (RXSQ) can provide heat pump heating with ambient temperatures as low as -4º F. However, it may be necessary to incorporate an auxiliary heat source to avoid oversizing the ODU to meet a low design day temperature or for heating in temperatures below -4º F. The switchover point from VRV heating to auxiliary heating is typically based on a balance point considering several factors such as climate, load, available capacity, fuel/system cost, and environmental impact.
VRV + Alternative Heat
VRV + Supplemental Heat
A gas furnace in a VRV system is considered an alternative heat method. At the switchover temperature the system switches over from entirely VRV heating to entirely gas furnace heating.
An electrical coil downstream of an indoor unit is considered a supplemental heat source. The electrical coil works in conjunction with the VRV system to provide heating beyond the balance point.

Gas Heat vs Heat Pump Auto Changeover VRV LIFE™ systems are capable of auto switchover from heat pump heating to gas heat at a gas furnace ambient engage temperature (balance point). A recommended switchover temperature is calculated in the WebXpress selection software and is configured at the ODU.
» Balance point: (G/F Engage Temp) is a field setting on the ODU, calculated balance point must correspond to valid field setting (2-14)
» Heat load: linear approximation from inputted heat load at design day and defined zero load ambient temperature (WebXpress Setting)

VRV IDU Auxiliary Heat Similar changeover logic is available for each VRV IDU via the Auxiliary heat PCB (KRP1C 74/75), see IDU accessories in WebXpress. A third party auxiliary heating device (ex. Electric heater) is required.
This would be necessary for zones needing auxiliary heat and that are being conditioned solely by a VRV IDU (no gas furnace).

Refrigerant Piping Design
REFNETs REFNET joints and headers are a factory designed option for the branching within the refrigerant piping network. These fittings are engineered to allow for uniform refrigerant flow and distribution, and smooth oil return.
REFNET Joint A REFNET joint splits a gas or refrigerant line into two lines. These joints account for approximately 1.5 feet of equivalent pipe length. It is allowable to install these joints in either a vertical or ±30º from horizontal. In noise sensitive applications it is recommended the clearances around a REFNET joint displayed below are maintained.
Note: 12" minimum distance on all scenarios above is possible. However, there is an increased risk of turbulent flow which may increase noise levels in the pipe.

REFNET Header REFNET headers are available in 4-port and 8-port configurations and account for approximately 3.3 feet of equivalent pipe length. Headers must be installed horizontally level and are typically installed suspended from the ceiling (spacing below).
Gas headers and liquid headers differ in that the branch piping extends from the bottom of the main header pipe for the liquid line while the gas line header extends horizontally from the header.
