Abstract

Park a car under sunlight without any sunshade for a several hours will cause the temperature in the car increase up to 60°C to 80°C depending on the outside temperature. The hot air in a car will make passengers are not comfortable to sit in the car. They have to switch on the air-conditioner and open the car's window for a several minutes to release the hot air from the car interior space. The hot air will also reduce the life time of the car interior such as a dashboard, seat and interior roof. Normally if the components are exposes to the sunlight frequently the color will change to pale color. The car dashboard, seat and air-freshener emits benzene when expose to high temperature. Actually the heated plastic smell in the car is benzene. The benzene can cause cancer, anemia and reduces white blood cells. The solar energy can be used to generate the electricity and convert to mechanical energy. In this research the electricity will be used to rotate the fan in the car. The fan will remove the hot air from car interior space to the surrounding through the air conditioner channel. The source of energy that rotated the fan is from solar energy. There are several experiments have been carried out in this project. The device used are four unit of 12V suction fan which powered by four unit of 12V solar panel. The water sprayer is also used to increase the humidity and then reduce the temperature. The results show that when a car is installed with all the devices, sunshade, two fans at front, two fans at rear and water sprayer it will able to reduce temperature in the range of 9.4% lower than the temperature of a car with only using two fans at front position and sunshade. It clearly shows that the hot temperature in a car interior can be reduced by using the solar energy during sunny day.
