✦ Synopsis

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 trensfer 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 mixture flow boiling inside enhanced surface tubing.
