Variable Refrigerant Flow (VRF) VRV Systems
Variable refrigerant flow (VRF) VRV is an air-condition system configuration where is is
One outdoor condensing unit and several indoor units. The term variable refrigerant flow
Refers to the ability of the system to control the amount of refrigerant flowing to the
Multiple evaporators (indoor units), enabling the use of many evaporators of differing
Capacities and configurations connected to a single condensing unit. The arrangement
Provides an individualized comfort control, and simultaneous heating and cooling in
Different zones.
Currently widely applied in large buildings especially in all the world The VRF – VRV technology / system was
Developed and designed by Daikin Industries, Japan who named and protected the term
Variable refrigerant volume (VRV) VRV system so other manufacturers use the term VRF – VRV
“Variable refrigerant flow”. In essence both are same.
