摘　　要：针对闷晒车辆车内温度过高问题,文章基于汽车光伏遮阳板供电的闷晒车辆进行了通风降温研究。采用当量满负荷运行时间法,分析驻车通风系统的功耗与光伏遮阳板的发电量,采用数值模拟方法对不同朝向闷晒车舱进行遮阳通风降温的仿真。仿真结果表明,使用光伏遮阳板维持2 m/s的驻车通风,可减少车舱空气14.27%的日总热负荷,最高可使车内空气温度降低11 K,减少人员进入车辆后27%的降温等待时间,并有盈余电量对汽车蓄电池进行充电维护。对比汽车光伏天窗与光伏顶棚,光伏遮阳板具有低成本、降温效率高和易于维护的优势。Aiming at the high interior temperature of sunburned vehicles,the ventilation and cooling of sunburned vehicles powered by photovoltaic(PV)sunshade is researched.The power consumption of the parking ventilation system and the power generation of the photovoltaic sunshade are analyzed using the equivalent full-load hour method.The numerical simulation and theoretical analysis are combined to study the cabin's shading and ventilation cooling with different orientations.The simulation results show that the total daily heat load of cabin air can be reduced by 14.27%.The maximum air temperature can be reduced by 11 K,and the cooling waiting time can be reduced by 27%after personnel entering the vehicle.There is surplus power to charge and maintain the vehicle battery.Compared with the automobile photovoltaic skylight and photovoltaic ceiling,the photovoltaic sunshade has the advantages of low cost,high cooling efficiency and easy maintenance.
