摘　　要：应用有限时间热力学理论 ,研究一类存在热阻和非理想回热的磁埃里克森制冷机的生态学优化性能 ,得到了制冷系数、制冷率等一些参数的新界限 ,并与最大制冷率工况进行比较 .所得结果可为磁埃里克森制冷机的研制和优化设计提供些新的理论指导 .By using finite time thermodynamics,the ecological optimal performance of a class of magnetic Ericsson refrigerators with thermal resistances and nonperfect regeneration is studied. Some new bounds of the parameters, such as the coefficient of performance, the rate of refrigeration, and so on, are obtained, and they are compared to those in the maximum rate of refrigeration regime. The results obtained here may provide some new theoretical guidance for the development and optimal design of magnetic Ericsson refrigerators.
