中文摘要:

      我国北方城市冬季地铁站内厅层工作区热环境特性对工作人员热舒适感非常重要。以青岛城市地铁有代表性的两个地下站的站厅层工作区热环境为研究对象，实验跟踪测试了站台层屏蔽门上部溢流活塞风扩散至站厅层的风量及气流温度变化规律；继而对厅层进出口自然流通的新风进行了风量和温度测试。实验研究发现，站厅层工作区的风速和气温受溢流活塞风和新风的耦合作用，呈现的周期性频率近似于溢流活塞风，而温度接近于新风，则站厅层热环境明显偏离常规热舒适性。面向站厅工作人员热环境及热舒适性进行研究，获取了青岛地铁地下站厅层工作区冬季热环境的特性。

英文摘要:

      The feature of thermal environment in working area of metro station hall layer is very important for the staff in north China, but there are few relative reports. The thermal environment of the hall layer of Qingdao metro station was studied in two representative stations in this paper. And the air flow volume and temperature change from the piston wind overhead screen door to the hall layer were tracking. Meanwhile, the test of the air flow rate and temperature of the new wind from passageway of the hall layer was carried out. It’s found that the wind speed and air temperature in the work area of the station hall are periodically coupled with the piston wind from platform, and the temperature is closer to the atmospheric temperature, causing the thermal environment of the station hall layer to deviate significantly from the thermal comfort. It is of practical significance to achieve the detail thermal environment characteristics of the metro station hall layer, and to improve the thermal comfort for the staff accordingly.
