摘　　要：室温磁制冷作为一种高效环保的新制冷技术,具备十分广阔的应用前景。文章阐述了室温磁制冷中磁性材料的最新发展情况,分析了磁Brayton与磁Ericsson制冷循环的热力特性,讨论了基于非Darcy效应的活性蓄冷器的多孔介质模型,介绍了新型室温磁制冷样机,并指出了室温磁制冷研究的方向。Room temperature magnetic refrigeration is a new highly efficient and environmentally protective technology, and it shows a great applicable prosperity. In this paper, the new development of the magnetic material is described. The thermal dynamic characters of magnetic refrigeration cycles are analyzed. The porous media model of active regenerator of room temperature refrigeration is discussed based on non - Darcian effects. Some new-style prototypes of room temperature refrigeration are presented. The further research of room temperature magnetic refrigeration is suggested.
