How does VRV work?

VRV is a technology that alternates the refrigerant volume in a system to match a building's precise requirements. Only a minimum amount of energy is required for a system to maintain set temperatures, and ensure that it automatically shuts off when no occupants are detected in a room. This unique mechanism achieves more sustainability in the long run, as end users save on energy costs while reducing their system’s carbon emissions.

With up to 64 indoor units connected to 1 outdoor unit, the VRV system operates similar to a Multi-Split system. Each individual indoor unit determines the capacity it needs based on the current indoor temperature and requested temperature from the remote control (set point).

The total demand among all indoor units will determine how the outdoor unit adjusts the refrigerant volume and temperature accordingly. By only supplying the cooling or heating that is needed, the inverter compressor continues to save a large amount of energy during VRV operation.

VRV 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 call it VRF.
