Abstract

Ventilation is an important system needed to apply in a closed space so that air can circulate and removed with the help of blower or fans. While parking a car under the open sun on a sunny day, heating of the car cabin cannot be avoided. It happens because solar radiation can come in to the car cabin through transparent glass, but cannot escape from it, hence results to heat trapped inside the car cabin. The purpose of this study is to design a ventilation system that can remove the heat trapped inside the car cabin. Such system needs electrical energy to operate the system, hence the utilization of solar power which convert solar radiation into electricity by using photovoltaic module. The design is based on the temperature inside the car cabin that is measured using thermocouples. The temperature inside the car cabin could increase up to 57˚C. The high temperature that trapped inside could cause discomfort when the driver or passenger enter the car. Hence, a proper ventilation system is designed to reduce the temperature. Experimental work is done to compare the temperature before a ventilation system installed and after a ventilation. An average reduction of 6.25˚C could be reduced after ventilation system is installed. The additional benefit other than provide comfort, the installation of a ventilation system inside the car cabin when it is parked under the open sun area could also avoid damage of rubber parts inside the car cabin. Since, photovoltaic is used, it saves electricity cost because solar radiation is free.
