Evaluation and Design of Large-Scale Solar Adsorption Cooling Systems Based on Energetic, Economic and Environmental Performance

In hot and dry regions such as the Gulf Cooperation Council (GCC) countries, cooling demand is often responsible for more than 70% of electricity consumption, which places a massive strain on grid leads to significant emissions. Solar thermal driven Silica-Gel/Water adsorption chillers, used space cooling, could provide low carbon emission reduce reliance electricity. However, meticulous design required make this both economically environmentally beneficial. This paper aims evaluate solar chiller performance based large-scale through TRNSYS simulation 1 year operation. The proposed system consists two main parts: first, loop with evacuated tube collectors; second, silica-gel/water chiller. A neighbourhood 80 typical 197 m2 villas in Riyadh, capital city Kingdom Saudi Arabia (KSA), was taken case study. cycle’s has been compared conventional vapour compression cycle terms energy, economic environmental performance. addition, parametric study performed parameters. Results reveal that can reach fraction 96% collector area 5500 storage tank volume between 350 400 m3. Furthermore, annual energy cost be reduced by 74% cycle. Meanwhile, CO2 saving percentage approximately 75% Carefully designed systems greenhouse gas emissions while covering large scale demands. well
