摘要
应用有限时间热力学理论,以广义不可逆卡诺制冷循环为对象,以[火用]经济性能为优化目标,研究了普适传热定律下循环的最佳性能,导出了循环有限时间[火用]经济性能界限以及优化目标之间的最佳关系,并分析了不同传热定律、各种损失和价格比因素对最佳[火用]经济性能的影响。所得结果具有普适性并可以为实际制冷机进行改良提供一种参考。
The optimal performances of a generalized irreversible Carnot refrigeration cycle with universal heat transfer law are studied. The research objective is exergoeconomic performance. The optimal relationships between the finite-time exergoeconomic performance bound and optimization objective are derived, and the effects of heat transfer laws, various losses and price ratio on the optimal finite-time exergoeconomic performance are analyzed. The obtained results are universal and can be a reference for the designs of practical refrigerators.
