摘要:

武汉地铁3号线列车空调系统采用中顶孔板与侧送风口相结合的送风方式，通过实车测试分析和数值模拟仿真分析的方式，分析了这种新型送风方式下车厢内的热舒适环境。测试结果表明：在距车厢地板高度0.5 m、1.2 m、1.7 m截面处的风速在0.35 m/s左右，车厢内任意两点处的温差小于3 ℃，车厢内环境满足列车空调系统设计规范。数值模拟仿真结果表明：列车空调系统采用中顶孔板与侧送风口相结合的送风方式，乘客的热舒适性较好，能够有效解决格栅送风方式中乘客吹风感的问题，提高了乘客乘坐的舒适性。

Abstracts:

Wuhan metro Line 3 adopts the ventilation mode of orifice plate with lateral inlet. Through real vehicle test and numerical simulation analysis, the carriage thermal comfort environment under this new type of air supply mode is studied. Test result shows that the wind speed at sections with 0.5 m, 1.2 m, 1.7 m from the carriage floor is around 0.35 m/s, and the temperature difference between any two points in the carriage is less than 3 ℃. That means the indoor environment of the carriage could meet the design code requirements for vehicle air conditioning system. The numerical simulation result shows that the passengers perceive better thermal comfort when orifice plate air supply mode is adopted, which effectively solves the draft sensation problem caused by grille air supply mode, and passenger riding comfort is consequently improved.
