【摘要】 为了研究屏蔽门式地铁站中非组织渗透风冷负荷的变化，基于上海市某地下非换乘屏蔽门式地铁站进行实测与仿真，建立了该车站非组织渗透风的简化仿真模型，再利用列车进出站过程中屏蔽门与出入口处的渗透风实测数据对仿真模型进行了验证，研究实验车站中非组织渗透风的动态变化规律，根据所验证的仿真模型计算得到了工作日及周末2个典型日的非组织渗透风动态负荷变化情况。结果表明：客流高峰期渗透风负荷会增加，且工作日与周末的最大渗透风负荷占比分别为29.8%与30.8%。更多还原

【Abstract】 To investigate the cooling load variation induced by unorganized infiltration airflow in platform screen door metro stations, field measurements and numerical simulations are conducted at a non-transfer underground platform screen door metro station in Shanghai. A simplified simulation model for unorganized infiltration airflow is developed and validated using on-site infiltration airflow data collected at platform screen doors and station entrances/exits during train arrival and departure cycles. The dynamic variation patterns of unorganized infiltration airflow are systematically analyzed, and the validated model is employed to calculate real-time infiltration load profiles for two typical scenarios of weekdays and weekends. The results show that the infiltration air load is increased during the peak passenger flow period, and the maximum infiltration air loads on weekdays and weekends are 29.8% and 30.8%, respectively.更多还原
