A cooling system includes a first heat exchanger for cooling a refrigerant, an expander configured to receive the refrigerant from the first heat exchanger at least one compressor configured to compress the refrigerant, an ejector configured to receive the refrigerant from the expander as a motive stream that evacuates and compresses the refrigerant from an evaporator, and a liquid separator coupled to an output of the ejector and configured to provide liquid refrigerant to an evaporator loop and vapor refrigerant to the at least one compressor. The evaporator loop includes an expansion device positioned to expand the liquid refrigerant from the liquid separator, and the evaporator configured to receive the refrigerant from the expansion device, heat the refrigerant from a heat load, and pass the refrigerant to the ejector.
