摘要
目前的地铁车厢热环境参数调控基准单一,带来热环境过冷或过热的问题。对寒冷地区代表性城市西安地铁4号线地铁开展冬夏季节的热舒适现场研究,结果显示:夏季西安地铁车厢内的热中性温度为22.7℃,适中的相对湿度和风速分别为60.0%、0.78 m/s;冬季西安地铁车厢内的热中性温度为12.2℃,适中的相对湿度和风速分别为72.0%、0.80 m/s。出行者期望车厢温度降低,湿度和风速增加,特别是在冬季出行期间。研究成果为制定因地制宜的地铁车厢热环境调控基准提供了理论支撑。
The single control standard of the thermal environment parameters of subway cars leads to the problem of supercooling or overheating of thermal environment.A field study in winter and summer was conducted on the thermal comfort of subway cars of Line 4 in Xi'an,a representative city in cold regions.The results show that the thermal neutral temperature was 22.7℃,the moderate relative humidity and wind speed were 60.0%and 0.78 m/s in summer.In winter,the thermal neutral temperature was 12.2℃,moderate relative humidity and wind speed were 72.0%and 0.80 m/s,respectively.Travelers expected cooler temperatures,increased humidity and wind speeds,especially during winter trips.The research results provide theoretical support for establishing the thermal environment control benchmark of subway cars according to local conditions.
