VRF System

Variable refrigerant flow (VRF) systems vary the flow of refrigerant to indoor units based on demand. This ability to control the amount of refrigerant that is provided to fan coil units located throughout a building makes the VRF technology ideal for applications with varying loads or where zoning is required.

The term VRF indicates the ability of the system to vary and control the refrigerant flow through multiple evaporator coils to provide individual temperature control in various mechanical comfort zones. ... The VRF heat pump system provides heating and cooling for all indoor units at a specific time

They are essentially the SAME , but the term VRV is copyrighted by Daikin. for example a system by Daikin may be called a VRV, but a similar system made by Fujitsu is a VRF. VRV = Variable Refrigerant Volume, VRF = Variable Refrigerant Flow.

As a system, Variable Refrigerant Flow (VRF) has a lot to offer in terms of efficiency, running costs, flexibility in use, and control. As with any system, it suits some buildings, applications, and climates better than others.
