Abstract: One of the most promising alternative energy sources has been recognized as solar energy. Solar energy may be utilized for electricity, solar thermal and power generation directly or indirectly. Sun adsorbing refrigeration systems require adsorbing qualities, which can be produced by concentrated solar energy collectors. Previous research has found that the collector components’ reflectivity transmittance is one of the characteristics that have a substantial impact on the performance of a solar adsorption refrigeration system. For the first time, the solar insolation of Reflectech mirror, a new solar concentration material was compared parametrically with three popular solar concentration materials (metallic film, aluminium film and polymer film) that have been used for solar adsorption application. The optimized simulation results revealed that employing Reflectech film in the design of the solar adsorption refrigerating system has the ability to reflect the maximum solar insolation of 144.5 W/m2 in comparison with metallic film with 119.75 W/m2, aluminium film with 100 W/m2 and polymer film with 68.67 W/m2. Thereby, implying that the Reflectech film has the potential of producing the highest system coefficient of performance than the other materials is under research for all periods under study.
