摘要
本文由热力过程损失导出计算制冷循环的总损失EL的表达式;并证明EL≥0.用这种分析法计算了使用非共沸工质的劳伦兹循环的总损失ELZ,并与逆郎肯循环对比.结果表明两者的制冷系数都受到工质吸热过程的平均温度和放热过程平均温度的制约.
This paper derives a general expression of exergy loss in thermodynalic process by which not only the calculation expression of total exergy loss EL in refrigeration cycle can be obtained, but also the result of EL≥0 can be verified.The total exergy loss EZ of Lorenz cycle with non-azeotropic working medium can be calculated by using the above method. In comparision with reverse Rakine cycle, it can be shown that the refrigeration coefficient of the two types of Cycle will be restricted by the average tempe...
