Room temperature magnetic refrigeration is a new highly efficient and environmentally protective technology. Although it has not been maturely developed, it shows great applicable prosperity and seems to be a substitute for the traditional vapor compression technology. This paper briefly describes the basic principle of magnetic refrigeration, analyzes the material selection standard of room temperature magnetic refrigeration, reviews the development condition of the room temperature magnetic refrigeration materials in recent years, and finally points out the problems that the room temperature magnetic refrigeration material faces in developing and suggests further research of room temperature magnetic refrigerant.
