Abstract

In this study, condensation heat transfer of R-600a (Iso-butane) has been analyzed experimentally over different finned tubes varying different parameters. These parameters like saturation pressure, wall sub-cooling temperature, fin geometry, refrigerant properties, and coolant flow rate are major factors affecting the performance of refrigeration and air-conditioning (RAC) systems. The parameters were varied within the range of operating conditions for most of refrigeration and air-conditioning systems. Based upon experimental data and exclusive analysis, best performing sets of different parameters have been concluded, and also a generalized correlation in non-dimensional form covering different parameters has been developed.
