Investigation of the nucleate boiling heat transfer on several commercially available enhanced tubes and smooth tubes was carried out in this study. The working refrigerants included R-22, R-123, R-134a, R-410A, and R-407C. Experiments were conducted at saturation temperatures of 0 °C and 20 °C. For the W-TX tube at a given saturation temperature, the heat transfer coefficients for R-410A are the largest and for R-123 are the lowest. For the highly structured surface, W-B tube, the heat transfer coefficients for R-22 and R-410A are comparable, while the heat transfer coefficients for R-407C are the lowest.
