초록

An integrated heat pump and hot water system including a water to refrigerant heat exchanger having a refrigerant evaporating circuit and a refrigerant condensing circuit that are in heat transfer relation with the water circuit. A bi-flow expansion valve with a positive shut off feature is mounted in the refrigerant liquid line connecting the indoor and outdoor coil of the heat pump. The refrigerant evaporator circuit is connected between the inlet of the compressor and the liquid line by an evaporator line that enters the liquid line between the bi-flo...
