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.

Installation Friendly

Automatic oil balancing

Easy access service door Without oil balancing pipe, the oil is balanced automatically. This simplifies system design and improves reliability.

Auto addressing indoor units

Outdoor units can address indoor units automatically, greatly reducing labor.

Easy access service door

When maintenance is needed, the front panel can be pulled out like a door instead of being pulled down, by which the screws are remarkably reduced, saving much labor.

Super Comfort

Quick cooling and heating

Startup and reaching maximum output in a short time, realizing quick cooling and heating.

Nighttime quiet operation at 10dB(A) reduced sound level

When quiet operation is required, this function can be configured by outdoor PCB to greatly reduce sound level.

Precise temperature control at ±0.5°C

With twin pressure sensors and twin EEVs, the refrigerant volume can be adjusted automatically to realize precise temperature control, improving indoor comfort.

Intelligent defrosting technology

According to system status to intelligently judge if defrosting is required, improving indoor comfort.
