Summary

Heat transfer and associated frictional pressure drop in the condensing flow of the ozone friendly refrigerant R410A in a vertical plate heat exchanger (PHE) are investigated experimentally in the study. The results indicate that the R410A condensation heat transfer coefficient and associated frictional pressure drop in the PHE increase almost linearly with the mean vapour quality, but the system pressure only exhibits rather slight effects. Finally, an empirical correlation for the R410A condensation heat transfer coefficient in the PHE is proposed. In addition, results for the friction factor are correlated against the Boiling number and equivalent Reynolds number of the two-phase condensing flow.
