摘要
应用熵理论对恒温热源、变温热源制冷系统进行了分析 ,提出了统一的效率表达式及各过程能量的不可逆损失计算式 ,将热源的差异归结为当量平均温度计算的不同 ,并给出了平均当量温度计算的具体方法 ,同时讨论了熵分析中的几个注意点 。
Based on the theory of entropy, analyzes the refrigerating systems working between constant temperature and variable temperature heat sources, puts forward an uniform efficiency formula and expressions of counting irreversible energy loss in every proceeds. The difference between constant and variable temperature heat sources is just the dissimilarity of equivalent average temperature, and its computational method is given. The authors note that the several points should be paid more attention to in entropy analysis. Overall, this paper provides a convenience way for teaching and engineering.
