Résumé

On the basis of the molecular-field theory and thermodynamics of the magnetic system, the relation between heat and magnetic entropy change of the regenerative room-temperature magnetic Ericsson refrigeration cycle was analysed in the study. Moreover, the influence of the temperature of the heat reservoir on the performance of the ferromagnetic magnetic Ericsson refrigeration cycle was investigated. The numerical simulation of the magnetic refrigeration cycle with typical ferromagnetic material Gadolinium was conducted. The results show that there will be an important change in the cycle performance near the Curie temperature. Whenever temperature is higher than Curie temperature, only the condition of occurs, otherwise, both conditions appear. In addition, the maximum of high-temperature heat reservoir increases with the increase in the low-temperature heat reservoir. And for the same heat reservoir, the increase rate decreases while magnetic field strength increases.
