摘要

Abstract

Three methods of calculating condensation heat transfer coefficient of mixture r efrigerants were compared. It was presented that the technique of gaseous heat r esistance was suitable for the engineering application. The other formulae in li teratures and the technique of gaseous heat resistance were separately compared with the experiment data. The results show that the technique of gaseous heat re sistance is better than the other formulae, where liquid film heat resistance ca n be more accurately calculated by modified Shah formula.
