Comparative study of two phase flow boiling of refrigerant mixtures and pure refrigerants inside enhanced surface tubing

Abstract:

In this paper, the characteristics of two phase flow boiling of pure refrigerant; R-22 as well as non-azeotropic refrigerant mixtures R-22/R-114 and R-22/R-152a inside horizontal enhanced surface tubing is presented. Correlations were proposed to predict the heat transfer characteristics of non-azeotropic refrigerant mixture flow boiling inside enhanced surface tubing. In addition, it was found that the enhancement of the heat transfer coefficient is dependent on the mixture components and their concentrations. © 1992.
