Programación de propiedades aplicadas a sistemas de refrigeración por absorción
Resumen
El objetivo de este trabajo es desarrollar un modelo computacional que ayude a predecir las propiedades termodinámicas de la mezcla CaCl2-LiBr-LiNO3-H2O, las cuales sean utilizadas para el análisis y simulación de sistemas de refrigeración por absorción. El estudio está basado en la metodología de interpolación múltiple desarrollada en el software Engineering Equation Solver (EES) y los valores obtenidos son comparados con aquellos obtenidos experimentalmente. Los resultados muestran que el modelo desarrollado predice adecuadamente las propiedades de presión de vapor, entalpía específica y calor específico y los máximos porcentajes de desviación obtenidos son de 9.34%, 0.027% y 0.15%, respectivamente. Además, los resultados de la simulación muestran que, para las mismas condiciones de operación, se obtiene un error del COP del 4.58% cuando el sistema opera a una efectividad de 1.0 (100% de su capacidad), mientras que el menor error del COP del 1.02% se obtiene a una efectividad del 0.6 (60% de su capacidad), en comparación con los resultados presentados en la literatura.
