Thermoelectric Cooling System for Vehicle Cabin during Parking Powered by Solar Photovoltaic Energy

When an automobile is parked in an open area, the temperature inside the cabin rises because heat is carried inside by convection, conduction, and solar radiation that enters via the windows. Elevated temperatures within the car's interior are not only harmful to passengers, but they can also deteriorate the plastic dashboard and electronic devices. A cooling fan, window film, and a sheet of aluminum foil to cover the windshield are utilized to reduce the amount of heat that builds up within the vehicle cabin. This research used a thermoelectric cooler powered by solar photovoltaic energy. The system consisted of two panels 660 watt, two GEL batteries 200 Ah, a solar charger, six thermoelectric modules, fins, and fans. The results show that the temperature inside the vehicle cabin lowered by 4°C without using the conventional air conditioning system, which used harmful refrigerants. The maximum coefficient of performance was 0.0138.
