About VRV

When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The name VRV * derives from this technology that we call “variable refrigerant volume.”

* VRV is a trademark of Daikin Industries, Ltd.
