Variable refrigerant flow (VRF) is a HVAC technology invented in Japan by Daikin company around 1982. Like ductless mini-splits VRFs use refrigerant as a cooling and heating medium. This refrigerant is conditioned by a single outdoor condensing unit, and is circulated within the building to multiple Fan-Coil Units (FCUs).
The modular design of VRF results in great energy savings providing occupants choice to air condition or heat only the zones in use. A VRF system provides exceptional dehumidification and temperature control by rapidly adapting to changing loads.
Following are the world’s reliable VRF system manufacturer:
- Panasonic
- Fujitsu
- Mitsubishi
- Daikin
