Summary:

AbstractThe cabin air temperature increases quickly and can reach 80°C when the vehicle parks in the summer sunlight which has the bad influence on the occupants entering comfort. Some luxury vehicles, like Audi A8[1], reduce the internal temperature through operating air-condition in advance or using on-board battery to drive the cabin ventilator, which requires relatively complex control system and limits the system's operating time because of energy consumption.This research adopts the solar wing as the ventilation power supply and accomplishes the cabin real-time heat rejection by achieving the steady air circulation for both inside and outside environment. First, the static thermal transfer model of the crew cabin is established. Then, on the basis of the parameters of the prototype ventilation pipe, the ventilation model for the outside circulation is built. After that, the parameters of the solar wing are determined according to the control target of the cabin internal air temperature. Besides, combination of the working conditions for both the solar wing and the ventilator are analyzed. Experiments have been conducted for verifying the static thermal transfer model and the ventilation model.The results show that the system can reduce the cabin air temperature with a maximum of 15°C, therefore, the occupant entering comfort is improved when vehicle is parking under the hot sun
