摘要
以西安地铁2号线西安北站、行政中心站、北大街站及小寨站4个典型换乘站为研究对象对冬夏季舒适性进行对比分析,探讨不同季节下环境参数对乘客舒适度的影响。基于现场环境测试和乘客主观问卷调查,得出以下结论:冬季地铁车厢温度较高为22.3℃,相对湿度偏低为28.2%,夏季地铁站内温度逐渐降低但车厢湿度较高为72.5%,高于人体舒适相对湿度范围上限。冬季车厢内CO_(2)浓度平均值为1517 ppm,超出地下车站公共区内CO_(2)日平均浓度要求。而夏季总体空气质量较好。通过计算得到车厢内热中性温度与中性相对湿度。冬夏季车厢热中性温度分别为16.18℃和26.16℃,中性相对湿度值分别为52.52%和50.31%。
A comparative analysis of winter and summer comfort is conducted in four typical interchange stations of Xi’an Metro Line 2,Xi’an North Station,Administrative Centre Station,Beidajie Station and Xiaozhai Station,to explore the influence of environmental parameters on passenger comfort in different seasons.Based on the on-site environmental tests and passenger subjective questionnaires,the following conclusions were drawn:the temperature in the metro compartments is higher in winter at 22.3℃,and the relative humidity is lower at 28.2%;in summer,the temperature in metro stations gradually decreases,but the humidity in the compartments is higher at 72.5%,which is higher than the upper limit of the human body’s comfort range of relative humidity.The average CO_(2)concentration in the carriages in winter is 1,517 ppm,which exceeds the requirement for the average daily CO_(2)concentration in the public areas of underground stations.In contrast,the overall air quality was better in summer.The thermal neutral temperature and neutral relative humidity in the compartment were calculated.The thermoneutral temperatures in the compartments in winter and summer were 16.18℃and 26.16℃,respectively,and the neutral relative humidity values were 52.52%and 50.31%,respectively.
