摘要

This research gives a thorough examination of the performance of solar air collectors, with a focus on two separate scenarios: single glazing and double glazing solar air collectors. To examine critical factors such as outlet temperature, thermal efficiency, and exergy efficiency, numerical analysis was performed and validated using experimental data. The results showed that the double glazing, outperforming single-glazed equivalent by 8 °C. Effective and exergy efficiency were also assessed, revealing that the double glazing was significantly higher than the single glazing in both efficiency indices approximately 42 and 64.78% showing its potential for more effective solar energy utilization. Environmental assessments, emphasized the benefits of the double glazing even more. Finally, the study examined the influence of mass flow rate, intending to determine ideal flow rates that maximize energy and exergy efficiency. Also, this study emphasizes the major benefits of double glazing solar air collector design with different aspect ratios, providing useful insights into enhancing the performance and efficiency of solar air collectors. These discoveries have practical implications for improving solar energy utilization in a variety of applications, including room heating, and drying.
