Abstract
A system includes a refrigeration system to exchange heat between a first cooling loop and a second cooling loop. The refrigeration system includes a pressure exchanger (310) that is to receive a first fluid at a first pressure and a second fluid at a second pressure and exchange pressure between the first fluid and the second fluid. The refrigeration system further includes a first heat exchanger (318) to exchange heat between the first cooling loop and a portion of the first fluid output from the pressure exchanger. The refrigeration system further includes a second heat exchanger (329) to exchange heat between a portion of the first fluid that is to enter the pressure exchanger and the second cooling loop.
Claims24
A system comprising:
- a refrigeration system to exchange heat between a first cooling loop and a second cooling loop, wherein the first cooling loop is configured to cool a plurality of servers of a datacenter, wherein the second cooling loop is configured to provide heat to a cooling tower to reject the heat to an ambient environment, and wherein the refrigeration system comprises:
- 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 heat exchanger configured to exchange first heat between the first cooling loop and at least a portion of the first fluid output from the first outlet of the PX;
- and
- a second heat exchanger configured to exchange second heat between at least a portion of the first fluid that is to enter the first inlet of the PX and the second cooling loop.
A system comprising:
- a refrigeration system configured to cool a plurality of servers in a datacenter, wherein the refrigeration system comprises:
- 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 heat exchanger configured to provide first heat from the plurality of servers to at least a portion of the first fluid output from the first outlet of the PX;
- and
- a second heat exchanger configured to provide second heat from at least a portion of the first fluid that is to enter the first inlet of the PX to a cold sink.
A system comprising:
- a refrigeration system configured to cool a plurality of servers, wherein the refrigeration system comprises:
- a pressure exchanger (PX) configured to receive a first refrigeration fluid at a first pressure via a first inlet of the PX, receive a second refrigeration fluid at a second pressure via a second inlet of the PX, and exchange pressure between the first refrigeration fluid and the second refrigeration fluid, wherein the first refrigeration fluid is to exit the PX at a third pressure via a first outlet of the PX, and wherein the second refrigeration fluid is to exit the PX at a fourth pressure via a second outlet of the PX;
- a first heat exchanger configured to provide first heat from the plurality of servers to at least a portion of the first refrigeration fluid output from the first outlet of the PX;
- and
- a second heat exchanger configured to remove second heat from at least a portion of the first refrigeration fluid that is to enter the first inlet of the PX.
