• A model to predict the behavior of finned tube evaporators working with R134a has been developed. For modeling of the refrigerant phase change, evaporation or condensation, the heat transfer and the pressure drop for the two-phase flow have to be calculated. Therefore, a number of correlations, the most recommended ones in the reviewed literature, have been analyzed and compared. The results of this comparison are presented for the evaporation and condensation heat transfer coefficients and for the evaporator frictional pressure drop CFD analysis is done by varying fluids like R134A and R407C on all the fin shape designs such as rectangular and circular fins. Thermal analysis conducted on evaporator with different materials such as aluminum alloy 7475 and copper.
