Refrigeration is the process of removing heat from an enclosed space or from a substance and transferring it to a place where it is unobjectionable. Magnetic refrigeration, based on the magneto caloric effect (MCE), has recently received increased attention as an alternative to the well-established vapor compression refrigerators for room-temperature applications. Conventional refrigeration systems are causing a great threat to the nature. We all are aware of the impact of refrigerants such as cfcs, hfcs, etc. but we still continue to use it. Why? It is mainly because of the non-availability of an alternative technology that is cost efficient.
