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 condenser configured to receive the first fluid from a compressor and provide corresponding thermal energy from the first fluid to a first environment. The system further includes a heat exchanger configured to receive the first fluid output from the condenser.
Claims17
A system comprising:
- a pressure exchanger (PX) configured to receive a first fluid 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, and wherein the second fluid is to exit the PX at a fourth pressure via a second outlet of the PX;
- a first condenser configured to receive the first fluid from a compressor and provide corresponding thermal energy from the first fluid to a first environment;
- a first heat exchanger configured to receive first fluid output from the first condenser and provide corresponding thermal energy from the first fluid to fluid input to the compressor;
- and
- a pump configured to receive the first fluid output from the first heat exchanger and provide the first fluid to the PX via the first inlet.
A method, comprising:
- causing, via a pressure exchanger (PX), pressure to be exchanged between a first fluid and a second fluid;
- causing, via a first condenser, corresponding thermal energy to be provided from the first fluid to a first environment;
- causing, via a first heat exchanger, corresponding thermal energy to be provided from first fluid output from the first condenser to fluid input to a compressor;
- and
- causing, via a pump, the first fluid to be provided to the PX via a first inlet of the PX.
A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:
- causing, via a pressure exchanger (PX), pressure to be exchanged between a first fluid and a second fluid;
- causing, via a first condenser, corresponding thermal energy to be provided from the first fluid to a first environment;
- causing, via a first heat exchanger, corresponding thermal energy to be provided from first fluid output from the first condenser to fluid input to a compressor;
- and
- causing, via a pump, the first fluid to be provided to the PX via a first inlet of the PX.
