Valuable Refrigerant Flow or VRF

Technology / Service Summary

The Daikin VRV system is a multi-split type air conditioner for commercial buildings that uses variable refrigerant flow control to maintain individual zone control in each room and floor.


Multi-split type air conditioner for commercial buildings such as office buildings, hotels.


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.


1.Inverter technology minimizes energy consumption.
2.Modular design of outdoor units and wide selection of indoor units ensure system designs that are ideally suited to the environments where they are installed.
3.Individual climate control settings for each zone, utmost in comfort to commercial building settings.
4.Large allowances for piping length and level difference provide a flexible layout.
