An experimental setup based on an inverse Rankine refrigeration cycle is used to obtain the heat transfer data in an R-134a refrigerant mini-tube evaporator set operated under constant heat flux conditions. A considerable amount of data was acquired to map the thermal performance of the evaporative process under analysis, 75% of which were used for training the ANN and 25% were reserved for prediction purposes. Several neural network configurations were trained and the most accurate was selected to predict the thermal behavior. The results obtained in this investigation reveal the convenience of using ANNs as an accurate predictive tool for determination of convective heat transfer rates inside mini-tube evaporators. 2016 artículo científico 1405-7743 https://www.redalyc.org/articulo.oa?id=40443470003 https://www.redalyc.org/journal/404/40443470003/ https://www.redalyc.org/journal/404/40443470003/html/ https://www.redalyc.org/journal/404/40443470003/40443470003.epub https://www.redalyc.org/journal/404/40443470003/movil en http://www.redalyc.org/revista.oa?id=404 Ingeniería.
