EXPERIMENTAL INVESTIGATION ON CONDENSATION HEAT TRANSFER OF R410A ON SINGLE HORIZONTAL PETAL-SHAPED FINNED TUBE
ABSTRAKT
Condensation heat transfer characteristics ofR410a on single horizontal smooth and petal-shaped finned tubes are experimentally investigated. The objective is to obtain the basic data for film condensation ofR410a on the novel enhanced condensation heat transfer tube. Experiments were carried out at saturation temperatures of 39° C and wall subcoolings from 0.9 to 8.3°C. The results show that the condensation heat transfer coefficients on the smooth tube are smaller than those predicted by the Nusselt analysis by 8.4%. The experimental enhancement factors provided by the petal-shaped finned tube range from 7.5 to 8.3.
