| 摘 要： | 对混合工质凝结换热系数常用的三种计算方法作了分析比较，同时利用收集到的混合工质局部凝结换热系数的实验数据，对文献中给出的计算式以及用Bell-Ghaly法计算的准确度作了对比，得出了在工程实际应用中采用Bell-Ghaly法时，注膜热阻用修正Shah公式计算的准确度较好的结论。

| Abstract: | Three methods of calculating condensation heat transfer coefficient of mixture refrigerants were compared. It was presented that the technique of gaseous heat resistance was suitable for the engineering application. The other formulae in literatures and the technique of gaseous heat resistance were separately compared with the experiment data. The results show that the technique of gaseous heat resistance is better than the other formulae, where liquid film heat resistance can be more accurately calculated by modified Shah formula. |
