Heat transfer of ternary mixtures inside enhanced surface tubing

Abstract:

Two phase flow heat transfer parameters such as coefficient of heat transfer and pressure drop observed during condensation of ternary azeotropic refrigerant mixtures R-404A (R125/R134a/R143a:44/4/52), R-407B (R32/R125/R134a:10/70/20), R407C (R32/R125/R134a:23/25/52) and R408A (R22/R125/R143a:46/7/47) are presented in this paper. Experiments showed that for Reynolds numbers higher than 3.00 E06, R-408A appears to have greater heat transfer rates than the other blends under investigation. Furthermore, it is quite evident from this data that R-407C has the highest pressure drop among the refrigerants under investigation. (C) 2000 Elsevier Science Ltd.
