Advantages of Developing Refrigerator Technology Using Stirling Cycle Cooler

Abstract

Compared with conventional vapour compression system, the refrigerator using Free-piston Stirling cooler (FPSC) based on reverse Stirling cycle has the advantages of high efficiency, green refrigerant, large range of cooling temperature, low starting current and easy capacity modulation operation. It's also energy saving and environment protecting. The advantages of using it in small capacity and low temperature refrigerators are analyzed according to the characteristics of FPSC. The research overview of Stirling refrigeration system in foreign countries is introduced, and then the prospects of developing Stirling refrigerator technology in our country are expected.
