摘　　要：客流密度是影响地铁列车客室内热舒适性环境的重要因素,传统的地铁列车客室温度控制主要是根据UIC-553标准,以室内外温差作为控制核心。本文通过构建全尺寸地铁列车客室-乘客-空调送风耦合的一体化模型,利用实车试验与数值模拟相结合的方法,对地铁列车客室内的热舒适性展开研究。探讨客流密度对地铁列车客室内热舒适环境的影响规律以及不同客流密度下客室平均温度与空调送风温度之间的关系,得到了不同客流密度下能满足人体热舒适性体验的空调送风温度,提出了一种基于客流密度的地铁列车空调夏季送风温度控制模型。Passenger density is an important factor affecting the thermal comfort environment of metro train passenger compartments.The traditional way for controlling the temperature of passenger compartments is mainly based on the UIC-553 standard,where the indoor and outdoor temperature difference is the core factor of the control.The present study constructed an integrated model which couple the passenger compartment,passengers and the air supply of air conditioners for a full-size metro train,and studied the thermal comfort of the passenger compartment by combining approaches of real vehicle tests and numerical simulations.The influence of the passenger density on the thermal comfort environment of the passenger compartment was discussed.A relationship between the average temperature of the passenger compartment and the air supply temperature of air conditioners under different passenger densities was established and the air supply temperature which can meet the human thermal comfort experience was obtained.Finally,an air supply temperature control model for the metro train air conditioner based on passenger density was proposed.
