Variable Refrigerated Flow (VRF) VRF systems feature simultaneous cooling and heating. Also called heat recovery, these systems enhance the capabilities of zoning technology considerably by using a branch circuit (BC) controller to control energy. The BC controller can remove energy from one zone that doesnâ€™t need it, and apply it to a different zone that does. For example, if an indoor unit in one room is calling for cooling and an indoor unit in another room is calling for heating, the BC controller can take the heat removed from the room operating in cooling and use it to warm the room in heating mode. The BC controller performs all the work, bypassing the compressor unit and saving electricity.
Closed-Loop Geothermal Heat Pumps The geothermal closed loop system provides heat from the water that is conditioned by the natural temperature of earth; this system uses heat pumps to transfer water through a building system providing a pleasant environment. The water both provides heat in a cooler environment and absorbs heat from warmer areas and circulates it to create a more desirable workspace.
