The Basics of Variable Refrigerant Flow Technology

VRF is an HVAC technology designed to provide energy-efficient comfort control for a building’s occupants according to the conditioning needs of a building’s zones. 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.
