磁Ericsson制冷机中热力学循环的优化研究

The Optimal Research of Thermodynamics Cycle on the Magnetic Ericsson Refrigerator

】文中考虑热阻不可逆性、循环过程的有限时间性和回热不平衡性，建立了顺磁质Ｅｒｉｃｓｓｏｎ制冷循环的模型。应用有限时间热力学理论，得出了最佳制冷率和制冷系数的优化关系，取得了一些有意义的结果，对实际工作有指导意义。

After the irreversibilities of the thermal resistance and the finite time of cycle and non-equilibrium of regeneration are considered, the modle of Ericsson refrigeration cycle on a paramagnetic material is established. Based on finite time thermodynamics theory, the optimal relationship between cooling rate and coefficients of performance is obtained. These valuable conclusions in this paper will provide some theretical reference for real magnetic refrigerators.
