What HVAC Contractors Should Know About Variable Refrigerant Flow Technology
Variant refrigerant flow technology is designed to give building occupants more comfort and more energy-efficient control via zoning. Supported by integrated controls and sensors, VRF accomplishes cooling and heating through the transfer of conditioned refrigerant between each zone’s indoor unit(s) and an outdoor unit.
As the name variable refrigerant flow indicates, VRF systems are able to modulate the flow of refrigerant so that the system only uses the precise amount of energy needed to meet each zone’s conditioning requirements.
