Variable refrigerant flow (VRF) systems, which were first introduced in Japan in 1982, have become popular in many countries; however, they are relatively unknown in the United States. VRF systems can condition multiple zones in a building, each of which may have different simultaneous heating and cooling needs. Using sophisticated control technologies, VRF systems can modulate the amount of refrigerant sent to each zone independently. This technology provides substantial energy savings by staying in tune with diverse and changing space conditioning loads.
