【Abstract】 A model of a class irreversible Stirling refrigerator is set up, the optimal performance of a Stirling refrigerator with generalized heat transfer law is studied. The optimal relation of refrigeration rate and refrigeration coefficient is derived. The effect of thermal resistance, heat leak and regenerative loss on optimal performance of Stirling refrigerator is discussed. The conclusions obtained here may provide some new theoretical reference for the optimal design of Stirling refrigerator.更多还原
