Abstract
Official abstract text for this publication.
A system ( 20 ) has a first compressor ( 22 ) and a second compressor ( 52 ). A heat rejection heat exchanger ( 30 ) is coupled to the first and second compressors to receive refrigerant compressed by the compressors. The system includes an economizer for receiving refrigerant from the heat rejection heat exchanger and reducing an enthalpy of a first portion of the received refrigerant while increasing an enthalpy of a second portion. The second portion is returned to the compressor. The ejector ( 66 ) has a primary inlet ( 70 ) coupled to the means to receive a first flow of the reduced enthalpy refrigerant. The ejector has a secondary inlet ( 72 ) and an outlet ( 74 ). The outlet is coupled to the first compressor to return refrigerant to the first compressor. A first heat absorption heat exchanger ( 80 ) is coupled to the economizer to receive a second flow of the reduced enthalpy refrigerant and is upstream of the secondary inlet of the ejector. A second heat absorption heat exchanger ( 90 ) is between the outlet of the ejector and the first compressor.
