The Parking’s Passenger Cabin Cooling System by the TEC with Air Conditioning Condensate Water Cooling 2019-01-1066
In the passenger cabin of the parking under the summer sun, the air temperature will reach about 55℃. Such temperature can cause discomfort to the person who has just entered the passenger cabin, also can damage components of the passenger cabin. The reason for this phenomenon is because it is not convective with the outside air. The Audi A8 and the Toyota Prius use the electric power to drive the blower in order to ventilate, but the air’s temperature of cabin is so high that the blower’s effect of ventilation is limited. The system proposes to use solar energy to drive the automobile blower and the thermoelectric cooler(TEC) in order to cool the cabin’s air, and use the air-conditioning condensate water collected during the driving process to cool the TEC’s hot end to improve the cooling efficiency. Establish a model of TEC, a mathematical model of the relationship between the condensate water’s phase change at the TEC’s hot end and the temperature of the hot end, and a mathematical model of the hot end temperature’s influence on the TEC’s cooling capacity. Using MATLAB to analyze the optimal cooling scheme by simulating TEC with condensate cooling system, designing a condensate water collecting device and a ventilation duct of installing TEC. Experiments will use a vehicle in which a solar panel was mounted on the roof, and verifying the cabin’s cooling effect of using condensate water. The experiment is expected to make the cabin’s temperature difference with the outside is within 5 °C in order to meet passenger comfort.
