Nucleate boiling performance of R22, R123, R134a, R410A, and R407C on smooth and enhanced tubes.

Author(s) : WANG C. C., SHIEH W. Y., CHANG Y. J.

Summary

Experiments were conducted at saturation temperatures of 0 and 20 deg C. For the W-TX tube at a given saturation temperature, the heat transfer coefficients for R410A are the largest and for R123 are the lowest. For the highly structured surface, W-B tube, the heat transfer coefficients for R22 and R410A are comparable, while the heat transfer coefficients for R407C are the lowest.
