Barocaloric heat transfer systems and methods of use

A heat transfer system comprising:

• at least one volume, wherein the at least one volume includes a first volume and a second volume, wherein the second volume is separate from the first volume wherein the first volume and the second volume are configured to be in fluid communication;
• a barocaloric material disposed in the at least one volume;
• a high pressure fluid source configured to supply a first fluid at a first pressure, wherein the high pressure fluid source is in selective fluid communication with the at least one volume;
• a low pressure fluid source configured to supply a second fluid at a second pressure lower than the first pressure, wherein the low pressure fluid source is in selective fluid communication with the at least one volume, and wherein the high pressure fluid source and the low pressure fluid source are configured to alternatingly flow the first fluid and the second fluid through the at least one volume;
• and
• a plurality of valves operatively associated with the first volume and the second volume, wherein the plurality of valves is configured to separately control a flow of the first fluid and a flow of the second fluid to both the first volume and the second volume.
