Abstract
A system has a compressor, a heat rejection heat exchanger, first and second ejectors, first and second heat absorption heat exchangers, and first and second separators. The heat rejection heat exchanger is coupled to the compressor to receive refrigerant compressed by the compressor. The first ejector has a primary inlet coupled to the heat rejection exchanger to receive refrigerant, a secondary inlet, and an outlet. The first separator has an inlet coupled to the outlet of the first ejector to receive refrigerant from the first ejector. The first separator has a gas outlet coupled to the compressor to return refrigerant to the compressor. The first separator has a liquid outlet coupled to the secondary inlet of the ejector to deliver refrigerant to the first ejector. The first heat absorption heat exchanger is coupled to the liquid outlet of the first separator to receive refrigerant and to the secondary inlet of the first ejector to deliver refrigerant to the first ejector. The second ejector has a primary inlet coupled to the liquid outlet of the first separator to receive refrigerant, a secondary inlet, and an outlet. The second separator has an inlet coupled to an outlet of the second ejector to receive refrigerant from the second ejector, a gas outlet coupled to the compressor to return refrigerant to the compressor, and a liquid outlet. The second heat absorption heat exchanger is coupled to the liquid outlet of the second separator to receive refrigerant and to the secondary inlet of the second ejector to deliver refrigerant to the second ejector.
