【摘要】 结合广州地铁隧道通风系统优化方案及站台设置屏蔽门后的实际情况,利用CFD计算模型分析了车站隧道采用典型气流组织方式下屏蔽门开启时的渗漏风量。分析了渗漏风量对车站公共区通风空调系统的影响,重新认识了地铁车站设置屏蔽门后地铁车站公共区的空调冷负荷。更多还原

【Abstract】 Based on the optimized tunnel ventilation system and the condition when platform screen door of Guangzhou metro are installed,this paper establishes CFD model and analyses the leakage air flow rate of the typical air organizing mode when platform screen door opens, and the influence to the cooling-load of the station public area, this paper holds that the cooling-load of metro public area when the platform screen doors a installed shall be re-evaluated.更多还原
