SUV 6座汽车乘客舱热舒适性研究
Research on thermal comfort of passenger compartment of an SUV vehicle
摘要：
以某SUV 6座纯电动汽车为研究对象，采用试验和仿真方法对乘客舱热舒适性进行研究。以某地夏季高温环境为研究背景，考虑了太阳辐射和人体生理热，采用PMV-PPD和相对湿度指标对乘客舱内的热环境进行分析和评价。结果表明，车舱内冷空气流速、乘客体表温度分布在舒适的范围内。通过分析评价指标的分布状态，可以清晰地了解乘客舱热舒适性情况，相较于实验更节约成本，缩短时间。
Abstract：
Taking an SUV 6 seat pure electric vehicle as the research object, the passenger compartment comfort is studied by experiment and simulation. Considering the solar radiation and human body model, PMV-PPD and relative humidity are used to analyze and evaluate the thermal environment of passengers. The results show that the velocity of cold air in the cabin and the surface temperature of passengers are within a comfortable range. By analyzing the evaluation index, we can understand the distribution of passenger compartment comfort, which has advantages of saving cost and shortening time compared with the experiment.
