Recent Car cabin cooling system works while the car is running or the engine is started. When the car stops or the car park is turned off, the cooling system automatically does not work and the cabin space becomes hot. In principle, the cooling system works by absorbing heat from the cooling room, as the cooling system that uses solar energy. In this study, solar energy is used to be converted into electrical energy which is then used in the car cabin cooling system. This study aims to obtain the maximum heat absorption where the minimum temperature in the car cabin is obtained. This research was a combination of three systems, namely the solar cell system, the thermoelectric system, and the cooling system itself. Solar and thermoelectric cells were placed on top of the car’s cabin, which is a cool chamber. On the upper side of the inside of the cooling chamber, a heatsink was used to get as much heat absorption as possible. The heatsink was attached to the cold side of the thermoelectric, while the hot side of the thermoelectric was closed so that the temperature can be controlled. Solar cells that face direct sunlight throughout the day (measurement time from morning to evening) would convert solar energy into electrical energy. Through a thermoelectric cooling system that is supplied with electrical energy from solar cells, the cooling system underneath would absorb the surrounding heat where the temperature of the cooling room would decrease in turn. The results showed that the cooling room conditions were as follows, namely the coefficient of performance (CoP) obtained by the cold room was 0.042 and the lowest temperature that could be reached was 25.60 oC.
