Variable refrigerant flow (VRF)
Variable refrigerant flow is an HVAC technology that uses refrigerant to condition the air using an outdoor condensing unit connected to multiple indoor units within a building. The outdoor unit has a variable speed compressor to modulate the flow of refrigerant through the evaporator coils in the indoor units. These can be 2-pipe (Heat Pump) or 3-pipe (Heat Recovery) systems.
PSE offers $3.00 per square foot of conditioned space for VRF systems.
