摘要:
运用CFD(计算流体动力学)软件研究送风格栅和中顶孔板与侧送风口两种送风方式对车辆客室热舒适性的影响。基于车辆客室不同截面的气流速度云图、温度云图、舒适性指标云图等数值结果，分析了车辆空调不同送风方式对车辆客室热舒适性的影响。结论为：在客室1.7 m高度处，采用中顶孔板与侧送风口送风时，整体的热舒适感有优势；在人体座位区域1.1 m高度处，采用格栅送风时，热舒适会更好。
Abstracts:
CFD (computational fluid dynamics) is adopted to study the influence of grille air supply mode and orifice plate air supply mode on the carriage thermal comfort. Based on the the simulation results such as fluid speed nephogram, temperature nephogram and comfort indicator nephogram of the carriage at different height sections, the influence of different ventilation modes on carriage thermal comfort is analyzed. It is concluded that at the 1.7 m height in the carriage, the orifice plate air supply mode performs better in terms of the overall thermal comfort; while at the 1.1 m height in passenger sitting area, the grille air supply mode contributes more to passenger’s thermal comfort.
