<p>A system has first and second compressors (22, 180), a heat rejection heat exchanger (30), an ejector (38), a heat absorption heat exchanger (64), and a separator (48). The heat rejection heat exchanger (30) is coupled to the compressor to receive refrigerant compressed by the compressor. The ejector (38) has a primary inlet (40) coupled to the heat rejection exchanger (30) to receive refrigerant, a secondary inlet (42), and an outlet (44). The separator (48) has an inlet coupled to the outlet of the ejector to receive refrigerant from the ejector. The separator has a gas outlet (54) coupled to the compressor (22) to return refrigerant to the first compressor. The separator has a liquid outlet (52) coupled to the secondary inlet of the ejector to deliver refrigerant to the ejector (38). The heat absorption heat exchanger (64) is coupled to the liquid outlet of the separator to receive refrigerant. The second compressor (180) is between the separator and the ejector secondary inlet.</p> |
