By using the finite-time thermodynamic theory,a Stirling refrigeration cycle model using ferromagnetic materials as working substance is set up, in which finite-rate heat transfer, regenerative losses are taken into account. On the basis of the thermodynamic properties of ferromagnetic material, the general performance characteristics of ferromagnetic Stirling refrigerations cycle are investigated. Moreover,the paper takes further steps to explore the exergoeconomical optimal performance of a ferromagnetic Stirling refrigerator with thermal resistances and regenerative loss. The results obtained here may provide some new theoretical guidance for the development and optimal design of ferromagnetic Stirling refrigerators.
