| 摘 要： | 以非共沸混合工质在蒸发器中沿程温度分布变化所导致传热不可逆熵增为目标函数，建立混合工质与冷媒水在蒸发器中的稳态换热模型，以换热温差最小值为基准，编程分析计算得出二元混合工质R290／R600在不同组分比下的相对熵增，选取其中最小值对应组分比为最佳组分比。

| Abstract: | Focusing on the irreversible gain of entropy resulting from temperature difference between non-azeotmpie reffigerant mixtures and the cooled water, the steady heat transferring model between nised working fluids and the cooled water has been constructed. Taking the minimum temperature difference as benchmark, a program to compute the relative gain of entropy in different ratios of the mixtures of R290/R600 has been compiled, and the ratio with minimum gain of entropy has been selected as optimM component ratio. |

| Keywords: | non-azeotropic component ratio steady heat transfer gain of entropy pmgram |
