摘要：

According to the Langevin theory, the expressions of magnetization and entropy of ferromagnetic material were derived and then an irreversible regenerative Ericsson refrigeration cycle using ferromagnetic material as the working substance is set up. The thermoeconomic and thermodynamic performance of the refrigeration cycle are analyzed and evaluated. The influences of finite heat capacity rate of the low temperature heat reservoir, the regenerator efficiency, applied magnetic field on the thermoeconomic performance as well as and the corresponding cooling rate and coefficient of performance are revealed. The results obtained may provide some parameter reference for the optimal design of actual magnetic refrigerators. © 2016, Science Press. All right reserved.
