摘要
广州地铁3号线在初期运行时,因二氧化碳超标曾经出现乘客不良反应的情况。结合该问题进行思考,对6号线的初期运行条件进行建模计算,分析其最不利区间的换气量和新风量,结果满足要求。经与3号线比较,认为6号线不会出现类似的问题。结果表明,"活塞"风量小、区间空气品质差、列车密闭性能太好、车厢内送回风方式设置不合理等,是导致3号线乘客"晕车"的主要原因。
At the earlier stage of operation of Guangzhou metro Line 3, unhealthy reaction of passengers appeared due to CO2 exceeding the standard. Accounting for this situation, the author established a model according to the earlier stage of operation of Line 6 to carry out calculation, with the ventilation volume and new air volume analyzed for the most unfavorable transit section. Results obtained satisfied requirements. Comparing with Line 3, it has been confirmed that similar problems will not occur on Line 6 and it has been shown that a small＇ piston＇ volume, bad atmosphere in transit tunnels, bad air - tightness of vehicles, unreasonable air flow in the carriages etc. were the causes for fainting of passengers on Line 3.
