REVIEW OF SOLAR SORPTION COOLING RESEARCH IN THE MENA REGION

This paper provides a brief overview of closed sorption cooling technologies, and highlights the research performed on them in the Middle East and North Africa region. The main findings are summarized and presented in tabulated and graphical forms. The reviewed studies are compared in terms of the working pair, the Coefficient of Performance, the normalized collector area, etc. The results show that the average cyclic Coefficient of Performance for the adsorption chillers was 0.41, whereas the average chiller Coefficient of Performance for the absorption chillers was 0.677. The research trends reveal that interest in solar sorption cooling was low in the 1980s and 1990s, and gradually increased during the 2000s. In addition, the most installed solar cooling system in the Middle East and North Africa region is utilizing absorption cycles.
