Abstract
A system () has a compressor (). A heat rejection heat exchanger () is coupled to the compressor to receive refrigerant compressed by the compressor. An ejector () has a primary inlet (40) coupled to the heat rejection heat exchanger to receive refrigerant, a secondary inlet (), and an outlet (). A separator () has an inlet () coupled to the outlet of the ejector to receive refrigerant from the ejector, a gas outlet (), and a liquid outlet (). One or more valves () 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 () 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.
