Conceptual design of a Solar Powered Adsorption Cooling System Under Different Climate Conditions in Morocco

The increasing cooling demand in Morocco has a significant impact on the power grid and contributes to CO2 emissions, exacerbating ecological issues such as global warming. It is urgent to develop clean, environmentally friendly, and low-carbon refrigeration technology to decarbonize the cooling process. This work aims to evaluate the potential of a solar adsorption cooling (SADC) system, based on a conceptual design, across various areas in Morocco through SIMULINK simulation. For a comprehensive evaluation, the solar adsorption cooling system prototype is built in Rabat and Agadir, two Moroccan cities, which are selected as reference systems. The sensitive analyses of SADC were conducted in 14 representative Moroccan cities.The results show that the studied solar adsorption system outperforms in a hot-climate area and is mainly influenced by ambient temperature and solar radiation. The solar coefficient of performance ranged between 4,998% and 7,148% for an irradiation between 869,43 and 548,57 W/m2.The performances reported in this study for Morocco make the proposed system a practical alternative for near-zero-carbon refrigeration powered by renewable energy. Still, it needs further enhancement to improve its performance.
