ABSTRACT:
A heat pump system for a residence or other occupied space utilizing a fuel-fired prime mover or heat engine to operate a refrigerant vapor compressor. With both the engine and compressor situated outdoors, heat is transferred between the building interior and the refrigeration circuit with a heat transfer fluid circuit that permits the refrigerant to be isolated outdoors. The heat rejected by the engine is carried into the building by an engine coolant circuit for space heating and water heating. The heat transfer fluid circuit and the engine coolant circuit, ideally, use the same liquid, a simplified pump arrangement, a common reservoir and a multi-channel conduit.
