dc.description.abstractThe present work aims to solve one of the few problems that absorption refrigeration systems present, which consists of the relatively long times to reach a pseudo-stable state, for this we studied what happens when the conventional generator is replaced by an exchanger heat through a dynamic simulation using the NH3-H20 mixture as a working torque in the Aspen Plus® software, in order to study the time it takes for the generation temperature to stabilize. Taking a system with a cooling capacity of 3.50 kW studied by (Viswanathan et al., 2013), found that when the temperature of the heat transfer fluid changes 10 ° C, the generation temperature takes a little less than 6 minutes with a generator, while with power generation was found to take less tan immediately for the system to stabilize. In addition, other tests were carried out that showed that the thermal accumulation is almost null in the proposed system.eng

dc.description.resumenEl presente trabajo pretende resolver uno de los pocos problemas que presentan los sistemas de refrigeración por absorción, el cual consiste en los tiempos relativamente altos en llegar a un estado seudoestable, para ello se estudió lo que ocurre cuando se sustituye el generador convencional por un intercambiador de calor mediante una simulación dinámica utilizando como par de trabajo la mezcla NH3-H20 en el software Aspen Plus®, con el fin de estudiar el tiempo en que tarda en estabilizarse la temperatura de generación. Tomando un sistema con una capacidad de refrigeración de 3,50 kW estudiado por (Viswanathan et al., 2013), encontraron que cuando la temperatura del fluido caloportador cambia 10 °C, la temperatura de generación tarda un poco menos de 6 minutos con un generador, mientras que se con la sustitución generador se encontró que el sistema tarda en estabilizarse inmediatamente. Además, se realizaron otras pruebas que demuestran como la acumulación térmica es casi nula en el sistema planteado.spa
