“Design, Development, and Analysis of a Solar Thermal Powered Automatic Air Purification System’’

Abstract: Air pollution in urban and industrial regions remains a significant threat to public health, often exacerbated by the high energy consumption and carbon emissions of conventional grid-powered purification systems (Sharma et al., 2025; Sharyani et al., 2025). This study presents the design and analysis of an automatic air purification system powered by solar thermal and photovoltaic energy (Sharyani et al., 2025; Suri et al., 2025). The proposed system utilizes a multi- stage filtration process, incorporating activated carbon and HEPA filters to effectively eliminate airborne contaminants (Sharma et al., 2025; Suri et al., 2025).

Field tests of the solar-powered prototype demonstrate an average removal efficiency of 90% for particulate matter (PM2.5) and a substantial reduction in indoor volatile organic compounds (Sharma et al., 2025). The integration of intelligent sensor technology and microcontrollers allows the system to monitor air quality in real-time and adjust its purification settings dynamically to optimize energy use (Sharyani et al., 2025; Suri et al., 2025). Furthermore, performance evaluations of hybrid solar collectors indicate that a total efficiency of 44.68% to 58.59% is achievable under varied conditions (Thinsurat et al., 2018). This research highlights a sustainable, low-maintenance solution for air quality management in environments such as dental clinics and healthcare facilities, where maintaining sterile air is critical (Sharyani et al., 2025).
