Abstract

Over the last few years, numerous deaths due to internal car heat have been reported. Problems arise when the temperature is too hot in the car cabin when the car parked in direct sunlight. The temperature inside a car can archive up to 80°C without the proposed system because the heat has been captured and accumulated. These thesis describe briefly the design and development of automotive passenger compartment cooling system by using solar power and to find out the temperature difference between three conditions. In this study, national sedan vehicle (Proton Persona) were used, this car will be exposed for 8 hours to direct sunlight for three conditions. The first condition is an experiment without solar car ventilator (benchmark data), second condition experiment with solar car ventilator and experiment with new product design concept are the third conditions. This experiment requires two car positions that are: south and east. The temperature measurement for this data collection was gained and analyzed by using thermocouple and data logger that is located at 13 points in the car. The maximum temperatures at front dashboard are 81.29°C for east and 79.57°C for south. The usage of solar car ventilator is found to reduce the maximum temperature at rear deck of the vehicle in a horizontal position as much as 15.39°C. The solar car ventilators are effective to reducing the rear temperature in passenger compartment during entire soaking period but it still cannot reduce greater temperature inside passenger car compartment.
