What is Variable Refrigerant Volume (VRV)


Variable Refrigerant Volume (VRV) system is an air conditioning system which able to control the amount of refrigerant flowing to the multiple indoor units, enabling the use of many evaporators of differing capacities and configurations connected to a single condensing unit. This arrangement can provides an individualized comfort control, simultaneous heating and cooling in different zones.


VRV used refrigerant as the cooling and heating medium, and allows one outdoor condensing unit to be connected to multiple indoor fan-coil units (FCUs), each individually controllable by its user, while modulating the amount of refrigerant being send to each evaporator. 
By operating at varying speeds, VRV units work at the needed rate allowing for substantial energy savings at part-load conditions. Heat recovery VRF technology allows individual indoor units to heat or cool as required, while the compressor load benefits from the internal heat recovery. 
Energy savings of up to 55% are predicted over comparable unitary equipment.
