Diseño de un absorbedor para un sistema de refrigeración por absorción

Abstract

En este estudio, se desarrolló un análisis teórico de un ciclo de absorción de etapa simple con intercambiadores de calor de solución y de refrigerante y en la simulación se tendrá en consideración una cantidad significativa de parámetros de desempeño. Se realizaron ensayos con cuatro mezclas binarias de pares refrigerante – absorbente. Se variaron los parámetros de desempeño de estas soluciones y se compararon con las condiciones de operación de las unidades del ciclo. Los coeficientes de desempeño (COP) y la proporción de eficiencia del sistema se compararon con un rango amplio de temperaturas de generador, absorbedor, condensador y evaporador. La simulación del absorbedor y su representación con el modelo actual fue exitosa, la validez de los resultados de la simulación se estableció al compararlos con otros estudios, mostrando una buena concordancia. El estudio revela la viabilidad de utilizar los fluidos de trabajo NH3/LiNO3 y R134a/DMAC en sistemas de refrigeración por absorción que utilicen fuentes de calor de bajo potencial como alternativas a los fluidos de trabajo más tradicionales como el LiBr/H2O y el NH3/H2O ya que los COP obtenidos fueron de 0.57 y 0.41 respectivamente.

In this paper, a theoretical analysis of a single stage absorption cycle was performed. Four binary mixtures consisting of refrigerant – absorbent were tested. The performance parameters of these solutions were varied and compared with the operation conditions of the cycle. The coefficients of performance (COP) and the efficiency ratio of the system were studied in a wide range of absorber, generator, condenser and evaporator temperatures. The simulation of the absorber and the overall system was successful and the validation of the results was established by comparing them with other studies, showing good agreement between them. The study reveals the viability of using NH3/LiNO3 and R134a/DMAC as alternative working fluids for single stage absorption systems using low potential heat sources, obtaining COP of 0.57 and 0.41 respectively.
