摘要
本文在内可逆卡诺制冷机模型的基础上,引进不可逆程度Ⅰ来描述传热以外的其它不可逆性,从而建立了不可逆卡诺制冷机模型,导出其基本优化公式一最佳制冷系数与制冷率间的关系。由此揭示了不可逆因素对制冷机各种优化性能的影响,并指出有限时间热力学理论时实际制冷机的重要指导意义。
In this paper, we introduce the degree of irreversibility to describe the irreversibilities other than heat conduction.Then, based on the endoreversible Carnot refrigerator, a model of irreversible Carnot refrigerator is established, and the fundamental formula——the relation between the optimal coefficient of performance and the rate of refrigeration of the model is derived. From the formula, the effect of irreversibility on various performances of a refrigerator is revealed. Moreover, it is pointed out that the theory of finite time thermodynamics has important instructive significance for practical refrigerators.
