Two-phase flow condensation characteristics of alternatives to R502 inside air/refrigerant enhanced surface tubing.

Author(s) : SAMI S. M., FONTAINE M.

Summary

The alternatives considered in the study are R507, R404A, R407B, and R408A. R407B has the lowest heat transfer rate compared to the other blends in the investigated range of refrigerant mass flow rates and heat flux. R404A has the highest convective pressure drop among the blends under investigation.
