摘　　要：磁致冷是一种把磁性材料的磁热效应应用于制冷领域的新技术 ,它具有高效、节能、无环境污染等优点 ,可作为气体压缩 /膨胀制冷的替代技术 ,受到世界各国的普遍重视 .本文概述了磁致冷原理、材料、室温磁致冷技术及磁致冷模型机的工作原理。Magnetic refrigeration technology is such a new technique that can make a good use of magnetocaloric effects of the magnetic material in refrigeration. It is characterized by many advantages such as high efficiency, energy saving, no environment pollution and so on, and can substitute for gas refrigeration by way of compression and expansion. As a result, great attentions are paid on the development and application of this new technology around the world. A brief summary of the principle and materials in the magnetic refrigeration field is given. The magnetic refrigeration technology at the near room temperature and its working principle and recent development are also introduced.
