With ground coupled systems water is taken from the ground or surface water (pond, lake, etc.), circulated to the individual heat pumps and the returned to the ground. With refrigerant loop systems a refrigerant such as R-22 is substituted for the water.
Furthermore, unlike most traditional HVAC systems, one condensing unit can handle more than one evaporator, each of which can be individually controlled by its user. This is done through the use of shared refrigerant. In a heat pump run VRV/VRF system, heating or cooling can be provided to the space.In a heat recovery VRV/VRF system, heating and cooling can be provided to variable spaces at the same time.By sharing the refrigerant throughout the system, rooms that need cooling give their heat to the system that in turn uses it to heat a room that needs heating and vice versa.ariable refrigerant volume (VRV) or variable refrigerant flow (VRF) systems are cutting edge mechanical systems with a proven track record.
