In this paper an experimental study of heat transfer characteristics of refrigerant mixture R-22/R-114 in the annuli of a horizontal enhanced surface tubing evaporator is presented. The enhanced surface tubing data showed a significant enhancement of the heat transfer compared to an equivalent smooth tube depending on the mixture's components and their concentrations. Correlations were proposed to predict the average heat transfer coefficients of R-22/R114 non-azeotropic refrigerant moisture flow boiling inside enhanced surface tubing.
