摘要： A system (200; 300; 400; 500; 600) has a compressor (22; 200, 221). A heat rejection heat exchanger (30)is coupled to the compressor to receive refrigerant compressed by the compressor. An ejector (38) has a primary inlet (40) coupled to the heat rejection heat exchanger to receive refrigerant, a secondary inlet (42), and an outlet (44). A separator (48) has an inlet (50) coupled to the outlet of the ejector to receive refrigerant from the ejector, a gas outlet (54), and a liquid outlet (52). One or more valves (244, 246, 248, 250) are positioned to allow switching of the system between first and second modes. In the first mode: refrigerant passes from the heat rejection heat exchanger, through the ejector primary inlet, out the ejector outlet, to the separator; a first flow from the separator gas outlet passes through the compressor to the heat rejection heat exchanger; and a second flow from the separator liquid outlet passes through a heat absorption heat exchanger (64) and through the ejector secondary port. In the second mode: refrigerant passes from the heat rejection heat exchanger to the separator; a first flow from the separator gas outlet passes to the compressor; and a second flow from the separator liquid outlet passes through the heat absorption heat exchanger to the compressor.
