    Abstract: 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.

    Abstract: An ejector (200; 300; 320; 340; 400; 430; 460; 480) has a primary inlet (40), a secondary inlet (42), and an outlet (44). A primary flowpath extends from the primary inlet (40) to the outlet (44) and a secondary flowpath extends from the secondary inlet (42) to the outlet (44), merging with the primary flowpath. A motive nozzle (100) surrounds the primary flowpath upstream of a junction with the secondary flowpath. The motive nozzle (100) has a throat (106) and an exit (110). The ejector (200; 300; 320; 340; 400; 430; 460; 480) further has a means (204, 210; 304; 322; 342; 402; 432; 462; 482) for varying an effective area of the exit (110) or simultaneously varying the effective area of the exit (110) and an effective area of the throat (106).

A second heat absorption heat exchanger (220) is coupled to the outlet of the second ejector to receive refrigerant. The separator (48) has an inlet (50) coupled to the outlet of the first ejector to receive refrigerant from the first ejector. The separator has a gas outlet (54) coupled to the secondary inlet (206) of the second ejector to deliver refrigerant to the second ejector. The separator has a liquid outlet (52) coupled to the secondary inlet (42) of the first ejector via the first heat absorption heat exchanger to deliver refrigerant to the first ejector.
