What is VRV or VRF?

You are here: Home » FAQs » What is VRV or VRF?

VRV is a system developed and designed by Daikin Industries that stands for "Variable Refrigerant Volume". Daikin protected the term VRV so other manufacturers use VRF "Variable Refrigerant Flow". In principle they both work the same and work extremely efficiently, are reliable, and an ideal energy saving solution for heating and cooling all types of buildings with minimum installation time or disruption.

The volume or flow rate of refrigerant within the VRV or VRF system is accurately matched to required heating or cooling loads thereby saving energy whilst providing more accurate control.
