VRV vs VRF

VRV (variable refrigerant volume) and VRF (variable refrigerant flow) are two different terms for the same technology. Because VRV is a trademark of Daikin Industries, Ltd., all other companies that copy this technology refer to it as a VRF system. 

VRV, introducing a new era of energy efficiency

When Daikin launched the VRV* air conditioning system in 1982, it introduced the world’s first use of variable refrigerant volume control. Also referred to as a VRF system, variable refrigerant flow is a technology that circulates only the minimum amount of refrigerant needed during a single heating or cooling period. This mechanism introduced the opportunity for end users to individually control several air conditioning zones at one time.
