摘要
对南方湿热地区某铁路站房开展了夏季热舒适现场研究,获取了不同功能区的环境参数、人员活动特征,以及热感觉、热舒适、热偏好、热可接受度投票,分析了不同区域的热舒适差异。研究发现:人员在候车厅停留时间显著长于门厅,候车厅人员热可接受度百分比与停留时间正相关;不同功能区室内空气温度最大相差5℃;不同功能区80%热可接受度的温度上限高于热中性温度3~4℃。利用人员在不同功能区的热适应差异,合理确定各类功能区环控方案,可为站房建筑节能降耗提供参考。
A field study is conducted in a railway station building in a hot and humid zone of southern China in summer.Thermal environmental parameters,personnel activity characteristics,and the votes of thermal sensation,thermal comfort,thermal preference and thermal acceptability in different functional areas are obtained.The thermal comfort differences in different areas are analysed.It is shown that the retention period of personnel in the waiting hall is significantly longer than that in the entrance hall,and the thermal acceptability percentage of personnel in the waiting hall is positively correlated with the retention period.The maximum difference of indoor air temperatures among different functional areas is 5℃.The upper limit temperature of 80%thermal acceptability in different functional areas is 3 to 4℃higher than the thermal neutral temperature.It is suggested to consider the thermal adaption differences of personnel in different functional areas and reasonably determine the environmental control plans for various functional areas,which can provide a reference for energy conservation and consumption reduction in station buildings.
