A VRF system consists of a DC inverter compressor with variable speed, electronic expansion valves (EEV), solenoid valves, and central controllers. This configuration enables the system to support a wide range of indoor unit capacities.

This system provides stable thermal comfort through intelligent energy management, precise temperature control, reduced power consumption and noise, as well as flexibility in selecting indoor units.

This technology is primarily used for air conditioning in large residential, commercial, and office buildings with variable thermal loads. It can also be integrated with solar systems or chillers to further enhance overall energy efficiency.
