Passenger Cabin’s Parking Cooling System Based on TEC and Air Conditioning Condensate Water 2019-01-1066

In the passenger cabin of the parking under the summer sun, the air’s average temperature will reach about 60°C. 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. Some vehicles 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 cooling 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. Experimental results: In the case of only turning on the blower, the system can reduce the 5°C air temperature of the air outlet, which has a good effect on the cabin’s temperature control and can satisfy the temporary comfort of the passenger in the vehicle.
