Abstract

See full text

A refrigeration system includes a gas cooler or a condenser configured to reject first heat from a first fluid that is at a first pressure and that is in a supercritical state or subcritical state. The refrigeration system further includes an evaporator configured to absorb second heat into a second fluid that is at a second pressure that is lower than the first pressure and that is in a liquid state, a vapor state, or a two-phase mixture of liquid and vapor. The refrigeration system further includes a rotary pressure exchanger configured to receive the first fluid from the gas cooler or the condenser, to receive the second fluid from the evaporator, and to exchange pressure, via a rotor of the rotary pressure exchanger, between the first fluid and the second fluid.
