During summer, specially in cities like Nagpur, cars parked under sunlight become extremely hot due to direct solar radiation. The temperature inside a closed car can rise significantly within a short time, making it uncomfortable and unsafe for the people., When the driver starts the car, the air conditioning system takes around 5 to 10 minutes to cool the cabin. During this period, the engine consumes extra fuel, leading to increased petrol usage and reduced mileage. This also contributes to higher emissions., Additionally, prolonged exposure to heat damages the car’s interior components such as the dashboard, seat covers and electronic systems. It can also reduce the lifespan of materials used inside the vehicle., This problem is common across all regions with high temperatures and affects daily peoples life increasing both cost and discomfort. Again due to high temp inside the car, air becomes suffocating and not good for respiration., There is a need to identify effective ways to reduce heat buildup inside parked cars using passive or alternative cooling methods which can help to improve comfort, save fuel and protect vehicle.
