摘要
室温磁制冷是一种既环保又高效节能的制冷新技术。尽管目前还不太成熟,但是它显示了广阔的应用前景,有望取代传统的蒸汽压缩制冷技术。简述了磁制冷的基本原理,分析了室温磁制冷的选材标准,综述了近几年室温磁制冷材料的发展状况,最后指出室温磁制冷材料在发展中所面临的问题,并对室温磁制冷材料未来的发展进行展望。
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.
