Abstract

A system includes a pressure exchanger (PX), a first heat exchanger, and a second heat exchanger. The PX is configured to receive a first fluid and a second fluid, exchange pressure between the first fluid and the second fluid, and output the first fluid and the second fluid. The first heat exchanger is configured to receive the first fluid from a first gas cooler and the second fluid from a second gas cooler, exchange first heat between the first fluid and the second fluid, and output the first fluid and the second fluid. The second heat exchanger is configured to receive heat exchanger output from the first heat exchanger and evaporator output from an evaporator, exchange second heat between the heat exchanger output and the evaporator output, and provide the heat exchanger output to the PX and the evaporator output to the compressor.
