VRV. How Does It Work?
Daikin’s Variable Refrigerant Volume (VRV) system changes the way you solve air conditioning problems.
At the heart of our system is a highly intelligent inverter-driven compressor. This advanced technology
enables the output of the outdoor unit tobe modulated by the cooling or heating demands
of the zone that it controls. Available in both heat pump and heat recovery formats, this advanced
system allows for individual control of up to 20 indoor units of varying capacities and types at a
connection ratio of 50% - 130% (8 and 16 Ton)compared to outdoor unit capacity.
The heat recovery function is achieved by diverting exhausted heat from indoor units in cooling mode
to areas requiring heating, and uses a Branch Selector (BS) unit to switch the indoor units from
cooling to heating mode. The entire pipe network is also facilitated by the use of the RefNet tubing
connectors, which reduces the installation time.The VRV system keeps running costs at an
absolute minimum by controlling each zone individually and being able to shut down
completely in unoccupied areas.

The VRV system integrates cutting-edge inverter technology to give you total control over your entire building. The intelligent inverter system gives added control
over the rotational speed of the compressor, which allows the amount of refrigerant flowing in the system to vary depending upon fluctuating needs. This delivers
maximum efficiency during partial load conditions and provides precise temperature control in all zones.
By using inverter technology, Daikin compressors run continuously at a minimum variable speed that matches the capacity of the current load. By running the
compressor continuously rather than ON/OFF, the room experiences better dehumidification and the compressor incurs less stress.
Features
Heat pump technology enables either cooling or heating from one system
Up to 24 indoor fan coil units connected to an outdoor unit
Cooling capacity of 6 / 8 / 12 / 14 / 16 tons available
Up to 1,024 indoor units can be operated on a single wiring system
Continuous operation 0°Fdb (-5Fwb) -64°Fdb (60 Fwb) in heating mode and 23°Fdb - 110° Fdb in cooling mode
Flexible piping lengths of up to 492 ft. or a total combined length of 1,000 ft.
Anti corrosion treatment
