【摘要】：本文基于有限时间热力学方法对具有回热的电化学制冷机性能进行了研究。系统的分析了参数对制冷机性能的影响。结果表明:电池的等温系数和电量密度越大越高,其性能系数和制冷功率越高。同时制冷机的工作范围也越广。存在最佳的高低温工作温度使制冷机的制冷功率,但是高性能的回热器不能显著增加制冷机的性能。冷热源温度对之比对最大制冷功率时制冷机的性能系数没有显著的影响,考虑到实际需求,制冷机应工作于最大制冷功率与最大性能系数之间,本文对电化学制冷机的设计和改进具有重大指导意义。
[Abstract]:In this paper, the performance of electrochemical refrigerators with regenerative heat is studied based on finite time thermodynamics. The effect of parameters on the performance of refrigerators is systematically analyzed. The results show that:. The higher the cell isothermal coefficient and the higher the charge density is, the higher the battery isothermal coefficient is. The higher the performance coefficient and the refrigeration power, the wider the range of work of the refrigerator. There is the best working temperature at high and low temperature to make the refrigeration power of the refrigerator. However, the high performance regenerator can not significantly improve the performance of the refrigerator. The temperature of the cold and heat source has no significant effect on the performance coefficient of the refrigerator when the maximum refrigeration power is maximum, taking into account the actual demand. The refrigerator should work between the maximum refrigeration power and the maximum performance coefficient. This paper is of great significance for the design and improvement of the electrochemical refrigerator.
