EVALUATION AND PARAMETERS AFFECTING OF HYBRID ACTIVE CARBONE-ETHANOL SOLAR ADSORPTION REFRIGERATOR

Abstract

The development of environmentally acceptable refrigerants and the use of solar energy and low-grade waste heat made adsorption refrigerators more appealing. However, more study is required to optimize these methods further as they do not yet match the performance and commercial application of typical vapor compression systems. This article illustrates the thermal response of adsorption systems under varying operating circumstances by simulating the pressure effect on temperature distribution in a porous adsorbent bed using ANSYS Fluent. Although heat transfer in porous media has been studied in the past, little is known about the precise function that pressure plays in influencing thermal behaviour. According to simulation studies, ethanol desorption efficiency is increased by greater inlet pressures because they provide more consistent and raised temperature distributions. varied x-positions  (2.9125 mm, 5.825 mm, and 11.65 mm) exhibit varied temperature profiles, which correspond to localized flow and pressure conditions. The results provide important insights into improving the design and functionality of adsorption-based cooling and separation systems by highlighting the predominant roles of heat conduction and vapor transport in determining thermal gradients.
