摘　　要：为了解决驻车高温问题,文中设计太阳能驻车通风与遮阳系统,建立乘员舱传热数学模型,通过实验验证模型准确性,并应用该模型对太阳能驻车通风与遮阳系统的降温与节能性进行分析。研究结果表明:在南昌市夏季典型气象条件下,相较于未采用任何乘员舱降温措施的停放车辆,采用太阳能驻车通风与遮阳系统的车辆乘员舱内热环境有明显改善,车舱内空气平均温度最高可降低9.4℃;车辆启动时的制冷负荷最多可降低27.3%。搭载该太阳能驻车通风与遮阳系统能极大地提高驾乘人员的舒适性,同时降低空调能耗。In response to the challenge of elevated temperatures in parked vehicles,a solar-powered parking ventilation and sunshade system was developed.A mathematical model for heat transfer within the passenger cabin was meticulously established and validated for accuracy through empirical experiments.Moreover,the model was employed to assess the cooling and energy-saving potential of the solar-powered parking ventilation and sunshade system.The research outcomes demonstrate that under typical summer weather conditions in Nanchang,vehicles equipped with the solar-powered parking ventilation and sunshade system significantly enhance the thermal environment inside the passenger cabin compared to vehicles devoid of any cabin cooling measures.The average cabin air temperature can be reduced by up to 9.4℃;the cooling load can be reduced by up to 27.3%.The solar-powered parking ventilation and sunshade system can greatly improve the comfort of drivers and passengers,while reducing the energy consumption of air conditioning.
