dc.description.abstract [EN] The optimum performance of a pure subcritical refrigeration cycle depends significantly on the temperature lift of the heat source and sink. Therefore, the maximization of the system efficiency has to be linked to them. This paper shows an exergy analysis of each heat pump component (condenser, evaporator, expansion valve and compressor) considering that the heat source and sink are not at constant temperature. The performed study shows the components with more possibilities for improvement. Based on this analysis, the optimization of cycle parameters like subcooling and superheat as a function of the external conditions have been done. In addition, this work has demonstrated that the components having a higher influence in the system irreversibility's depends significantly on the temperature lift of the secondary fluids. Finally, the obtained results show potentials improvements of the efficiency up to 23% if the system is able to operate in the optimal subcooling and superheat. es_ES
dc.description.sponsorship Part of the results of this study were developed in the mainframe of the FP7 European project 'Next Generation of Heat Pumps workingwith natural fluids' (NxtHPG). Part of the work presented was carried by Miquel Pitarch with the financial support of a PhD scholarship from the Universitat Politecnica de Valencia. Part of the work presented was carried by Estefania Hervas-Blasco with the financial support of a Ph.D. scholarship from the Spanish government SFPI1500X074478XV. The authors would like also to acknowledge the Spanish 'MINISTERIO DE ECONOMIA Y COMPETITIVIDAD', through the Project ENE2017-83665-C2-1-P, "Maximizacion de la Eficiencia y Minimizacion del Impacto Ambiental de Bombas de Calor para la descarbonizacion de la calefaccion/ACS en los proximos edificios de consumo energetico casi nulo" for the given support. es_ES
