Résumé

In this article, the experiment is carried out with four stages of test section and new experimental data of non-azeotropic refrigerant mixtures R22/R124 are presented. Existing correlations are analysed and new ones are proposed for pure refrigerants. The nucleate boiling correlation of the refrigerant mixtures is modified so as to obtain the evaporation heat transfer coefficient of the refrigerant mixtures in a smooth tube. The result shows that the majority of the predictions fall within plus or minus 30% of the experiments. [Reprinted with permission from Elsevier. Copyright, 2008].
