Development of Solar Evaporative Cooling System

Significant challenges are presented by global warming, which is caused by rising levels of carbon dioxide (CO₂), nitrogen oxides (NOx), sulfur oxides (SOx), and other pollutants. As global temperatures rise, finding sustainable cooling solutions becomes crucial. Solar evaporative cooling systems offer a promising alternative. These systems utilize renewable solar energy, reducing dependence on fossil fuels, and consume significantly less electricity compared to traditional vapor compression refrigeration-based air conditioners (VCRC). By harnessing solar power and water evaporation, they leave a smaller carbon footprint. Unlike air conditioners, which recirculate indoor air, evaporative coolers draw in fresh outdoor air. Their simple design makes solar evaporative coolers relatively easy to construct and maintain. While solar evaporative cooling has numerous benefits, challenges such as humidity control, cooling efficiency, maintenance, and geographic suitability need to be addressed. Despite these obstacles, solar evaporative cooling provides a sustainable and environmentally friendly solution for indoor comfort. By overcoming these challenges and leveraging solar energy, efficient cooling systems can be developed that benefit both people and the environment. The research work involves designing and constructing both the internal and external units of a solar evaporative cooling system, followed by performance testing. The focus will include selecting efficient cooling pads or media, designing an effective solar collector, optimizing airflow patterns, and ensuring efficient water distribution. Additionally, the research will explore ways to enhance the overall efficiency and effectiveness of the system, taking into account various environmental and operational factors. By addressing these aspects, the research aims to develop a robust and reliable solar evaporative cooling system that can be widely adopted for sustainable indoor cooling.
