Study of a Hybrid Magneto-Caloric Refrigerator and it’s Applications in the Industry

This paper presents a new refrigeration system that does not use any refrigerant gas. The design consists of a device for transporting heat from a cold to a warm reservoir, in which at least two cyclic processes are used for transporting heat, thereby absorbing work, of which at least one’s regenerative cyclic process, and at least one is a magneto caloric cyclic process, wherein the regenerative cyclic process has a working fluid and a heat storage medium, is characterized in that the heat storage medium of the regenerative cyclic process comprises a magnetocaloric material for the magneto-caloric cyclic process, wherein the magneto-caloric material is in a regenerator area with a cold end and a warm end, the working fluid of the regenerative cyclic process additionally serving as a heat transfer fluid for the magneto-caloric cyclic process.
