一、绪言制冷工作者总是希望能得到一种高效率、结构简单、操作方便,消耗能量少的制冷机。因此,在技术上得从两方面发展,一方面制冷工程技术人员着眼于已有制冷系统的改进,选用新型的节约能源的系统,改进传热设备的效率,使现有的装置更趋于合理。作为物理工作者来说,从一般基础理论中,不断地提出新的制冷原理,为制冷工程提供更全面的理论基础,新型的高温磁制冷机就是在这样的基础上产生的。
First, the introduction Refrigeration workers always hope to get a high efficiency, simple structure, easy operation, low energy consumption of the refrigerator. Therefore, technically, it has been developed from two aspects. On the one hand, the refrigeration engineering technicians focus on the improvement of existing refrigeration systems, choose new energy-saving systems, improve the efficiency of heat transfer equipment and make the existing devices more reasonable . As a physical worker, from the general basic theory, constantly put forward a new cooling principle for the refrigeration engineering to provide a more comprehensive theoretical basis, a new type of high temperature magnetic refrigerator is produced on this basis.
