Abstract

This paper presents a study on solar based car ventilation system by observing its effectiveness in reducing the temperature inside the car that is parked unroofed under the sun. The performance of the motor, power produced from the solar panel, airflow rate effect, tilt angle effect and air duct effect were investigated. A commercially available ventilator and a redesigned ventilator have been used to benchmark the analysis. The present study shows that the commercial ventilator only provided 6.86% of reducing interior temperature inside a car compared to without ventilator. Size of solar panel, placement and position angle as well as air duct became contributing factors that affect the performance. A redesigned ventilator that considers those factors is developed and analyzed. From result, a redesigned ventilator provided at least 19.83% better result of reducing the interior temperature inside the parked car as compared to the existing ventilator.
