Simulation and Analysis on Heat Transfer and Pre-cooling Characteristics of New Solar Power Vehicle Parking Ventilation System 2016-01-1732

When the vehicle parks in direct sunlight conditions, the cabin will form a high-temperature thermal environment in hot weather. Drivers would turn on the air-conditioning with relatively high gear in the most conditions to reduce the cabin temperature, which could affect the life of equipment, resulting in energy waste and increasing emissions. This study adopted solar energy in the ventilation system. When the car parks the cabin blower was driven by a solar panel mounted on the car roof to discharge heat inside the cabin real time, achieving the purpose of pre-cooling.
Firstly, heat transfer model and ventilation cooling model for the cabin were established according to the theory of heat transfer, and models were modified through experiments. Besides, the impact of ventilation flow rate on the pre-cooling effect was studied based on simulation analysis. Finally, comprehensively considering the solar panel power and cooling effect, a reasonable range of ventilation flow rate was obtained. Results shows that reasonable range of ventilation flow rate is 25 L/s ∼ 30 L/s, at this time temperature difference between the inside and outside the cabin could be controlled in 7 °C∼9 °C.
