US 12,007,154 B2 · Heat pump systems with pressure exchangers

Abstract

A system includes a pressure exchanger (PX) configured to receive a first fluid at a first pressure, receive a second fluid at a second pressure, and exchange pressure between the first fluid and the second fluid. The first fluid is to exit the PX at a third pressure and the second fluid is to exit the PX at a fourth pressure. The system further includes a first heat exchanger configured to provide the first fluid to the PX and provide corresponding thermal energy from the first fluid to a third fluid. The system further includes a turbine configured to receive the third fluid output from the first heat exchanger. The turbine is further configured to convert corresponding thermal energy of the third fluid into kinetic energy.

Dependent claims

A system comprising:

a pressure exchanger (PX) configured to receive a first fluid of a heat pump cycle at a first pressure via a first inlet of the PX, receive a second fluid at a second pressure via a second inlet of the PX, and exchange pressure between the first fluid and the second fluid, wherein the first fluid is to exit the PX at a third pressure via a first outlet of the PX to a chamber of a receiver of the heat pump cycle, and wherein the second fluid is to exit the PX at a fourth pressure via a second outlet of the PX;
a first heat exchanger configured to provide the first fluid to the PX via the first inlet and provide corresponding thermal energy from the first fluid of the heat pump cycle to a third fluid of a power generation cycle;
and
a turbine configured to receive the third fluid from the first heat exchanger, and wherein the turbine is further configured to convert corresponding thermal energy of the third fluid into kinetic energy.
