摘要

对非共沸混合工质R32/R134a在5种水平微翅管内的流动沸腾特性进行了实验研究，获得了传热系数随质量流量、热通量及干度的变化关系，并对各种工况下的换热机理进行了分析和讨论.同时，对R22和R32/R134a在微翅管与光管内水平流动沸腾传热系数进行了比较.

Abstract

Flow boiling heat transfer performance of non-azeotropic refrigerant mixture R32/R134a in the horizontal microfin tubes with different sizes was investigated. The dependencies of forced flow boiling heat transfer coefficient of R32/R134a on mass flow rate

heat flux and quality were studied and the mechanism of flow boiling heat transfer under each working condition were analyzed. The experimental data indicated that the component of R32 has affected the heat transfer coefficients of the mixture. For comparison

the performance of heat transfer of R22 in microfin tubes was also studied.
