ABSTRACT:
A heat pump heating and cooling system includes a compressor, indoor and outdoor heat exchangers, and two expansion devices. Interposed between the expansion devices is a cut-off device which permits refrigerant to flow between the indoor and outdoor heat exchanges while the compressor is operating, and blocks such flow while the compressor is idle, thereby isolating high and low pressure fluids from one another while the compressor is idle.
