In this paper, an experimental study on the heat transfer characteristics of two-phase flow condensation of alternative refrigerant mixtures to R-502 is presented. The test section was a horizontal, enhanced surface tubing in a water-to-refrigerant heat exchanger setup. Correlations were proposed to predict condensation heat transfer characteristics, such as average heat transfer coefficients, as well as the heat flux of R-502 alternatives: R-404a, R-507, R-408a, and a quaternary blend, R-32/R-125/R-143a/R-134a. In addition, it was found that the proposed correlations predicted the heat transfer characteristics with a deviation of less than ±20%.
