What is it about?

Cooling systems usually run on electricity, which increases energy costs and greenhouse gas emissions, especially in hot climates. This study analyzed the technical and economic feasibility of using solar-powered absorption cooling systems instead. These systems use heat from solar collectors to drive cooling cycles, reducing dependence on electricity. We evaluated different design configurations, local weather conditions, and energy demands to see when and where these systems could work efficiently. The analysis showed that solar absorption cooling is technically feasible and can be cost-effective in sunny regions, especially when electricity prices are high or when energy savings are prioritized.

Why is it important?

Air conditioning is a significant source of energy consumption and emissions worldwide. This work is important because it shows that clean solar energy can directly power cooling systems, reducing both costs and environmental impact. By providing a clear technical and economic roadmap, this study helps engineers and decision-makers design sustainable cooling solutions that are less dependent on fossil fuels, especially in developing regions with high cooling demand.

Perspectives

This research supports the transition to sustainable cooling by proving that solar absorption systems are a viable alternative to conventional air conditioning. Future studies can focus on large-scale deployment, integration with energy storage, and combining solar with waste heat or district cooling networks. This approach can accelerate the move toward greener and more energy-efficient cities.
