回热式磁布雷顿制冷循环

Regenerative Magnatic Brayton Refrigeration Cycle

应用热力学理论,导出以顺磁质为工质的回热式磁布雷顿制冷循环的制冷量和制冷系数,并讨论回热对循环性能的影响,得出一些新的结论,可供磁制冷机研制时参考和应用。

By using thermodynamic theory, the rating of refrigeration and the coefficient of performance of the regenerative magnetic Brayton refrigeration cycle with a paramagnetic material as working substance are derived, and the effect of regeneration on the performance of the cycle is discussed. Some new significant conclusions are obtained. They may be consulted and used for the research and manufacture of magnetic refrigerators.
