Performance Optimization Study of an Adsorption Solar Refrigerator System with Special Reference to the Effect of the Collector-Adsorber Tilt Angle

Abstract

This paper presents an optimization study of an adsorption solar refrigerator through dynamic modeling and simulation of the system behavior using the zeolite/water couple. Thus, a mathematical model representing the evolution of heat and mass transfer at each component of the adsorption solar refrigerator has been developed. The results of this study showed that increasing the angle of inclination of the collector from 0° to 13° with respect to the horizontal causes an increase in the temperature of the zeolite. The result is an increase in the mass of water vapor cycled, but also an improvement in the performance of the solar refrigerator. When the value of the angle of inclination exceeds 13°, the mass of water vapor cycled decreases and subsequently leads to a decrease in the performance of the refrigeration system.
