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.)

Warm Up/Pull Down Operation: prolonged periods of not conditioning the space, or setback periods, may result in entering air conditions (EAC) at the indoor unit (IDU) in these “warm up” and “pull down” ranges. Actual continuous operation EAC’s should fall within the “range for operation” temperatures.

To Other VRV IDU (s)

Standard pipe sizes are recommended. However, there are applications where larger sized refrigerant lines exist due to previously installed HVAC systems. Replacement of existing refrigerant lines can pose challenges, VRV LIFE™ systems can be configured to re-use these refrigerant lines. See the table below for allowable connection sizes. See ODU installation manual for field settings when using non-standard sizes.

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

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.

Example: Both indoor and outdoor units have a capacity index number and the connection ratio is defined as the ratio of these two numbers.

» 2 x FXMQ36PB connected to 1 RXSQ60T = 72 / 57 = 1.26 » Therefore the Connection ratio = 126%

The maximum connection ratio on VRV LIFE™ systems (RXSQ) is 130%.

Indoor Unit ConsiderationsGas Furnace & VRV A-Coil

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

EXPOSED units often offer the home owner the most economical installed cost solution on a VRV LIFE™ system. These types of units are ideal for applications that do not have a ceiling void available or the attic does not allow for a viable duct run. Exposed units are common in historic homes or applications where minimal reconstructive work is desired.

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.

Heat Pump Changeover

Return AirSensor

AUTO CHANGEOVERvia Master Unit

MANUAL CHANGEOVER

via MasterController

MasterController

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.

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.

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)

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.
