Influence of Operating Temperatures on the Solar Adsorption Refrigeration Machine Using the Activated Carbon-Methanol Pair

Abstract

In this work, we make a detailed analysis of the effects of the operating temperatures (Ta, Te, Tc, and Tg) of our solar adsorption refrigerator using the activated carbon-methanol couple on the thermal coefficient of performance (COPth) and on the quantity of methanol cycled in this machine. The mathematical model used in this part is based on the equation of state of the Dubinin-Astakhov model and the quantities of heat involved during the thermodynamic cycle of the refrigerator. For the validity of our mathematical model, the result of the calculation of the coefficient of performance obtained is compared with the result of Ch. Wassila, who had to work in this field by obtaining very satisfactory results compared to those available in the literature.
