地铁车厢空调系统的工作性能对于车内乘客的热舒适性有着直接影响。以某型地铁车厢为研究对象,运用计算流体动力学(CFD)Fluent软件,对车厢内空气流动进行数值模拟,根据国内外相关热舒适性标准,分析车厢内各主要区域的乘客热舒适性。结果表明:车厢内乘客周围温度、风速总体满足热舒适性要求,但坐态乘客的热舒适感较差。 The performance of the subway car air-conditioning system has a direct impact on the thermal comfort of passengers in the car. Taking a certain subway train as the research object, CFU Fluent software was used to simulate the air flow in the passenger compartment. The thermal comfort of passengers in all the main passenger compartment was analyzed according to the relevant domestic and international thermal comfort standards. The results show that the ambient temperature and wind speed in the passenger compartment satisfy the requirements of thermal comfort as a whole, but the passenger comfort in sitting state is poor.
