Abstract
A Stirling refrigeration system is disclosed that comprises a Stirling unit having a hot end and a cold end. In addition, the Stirling refrigeration system includes a hot heat exchanger fluidically coupled to the hot end and configured to release the heat form the hot end, wherein the hot heat exchanger and the hot end define a hot circuit for a first refrigerant to flow therein. Further, the Stirling refrigeration system includes a cold heat exchanger fluidically coupled to the cold end and configured to remove the heat from the cold end, wherein the cold heat exchanger and the cold end define a cold circuit for a second refrigerant to flow therein. One of the first refrigerant and the second refrigerant comprises a two-phase low GWP refrigerant.
