By using the finite-time thermodynamic theory, a new magnetic refrigeration cly cle model using ferromagnetic materials as a clycle working substance is set up, in which finite-rate heat transfer, heat leak and regeneration time are taken into account. On the basis of the thermodynamic properties of a ferromagnetic ma terial, the general performance characteristics of the ferromagnetic Stirling re frigeration cycle are investigated.Moreover, the ecological optimal performance of a ferromagnetic Stirling refrigerator with thermal resistances and regenerati ve loss is studied. The results obtained here can provide theoretical guidance f or the development and the optimal design of the ferromagnetic Stirling refriger ators.
