摘要
建立以铁磁材料为工质的不可逆磁斯特林制冷循环新模型,探索有限热源、热阻、回热损失和回热时间等对制冷循环性能的影响,应用有限时间热力学方法,导出制冷率与制冷系数间的优化关系解析表式,进而获得最大制冷率及其它优化性能参数.
The new model of an irreversible magnetic Stirling refrigeration cycle using ferromagnetic materials as the cyclic working substance is set up, in which the influence of finite heat capacities of external reservoirs, heat resistance, regenerative losses and regenerative time are taken into account. By using the method of finite - time thermodynamics, the optimal expression between the cooling rate and coefficient of performance is derived. Moreover, the maximum cooling rate and other optimal performance parameters are obtained.
