大型航站楼室内物理环境质量实测与时空特征分析研究

Analysis of Spatiotemporal Characteristics of Indoor Physical Environmental Quality in Large Terminal Buildings Based on Field Measurement

本研究以某大型航站楼为研究对象,开展了长期的室内环境质量监测工作。室内热湿环境测试结果表明,夏季与冬季室内PMV满足-1至+1要求的比例分别为92.9%与92.7%。在空间分布上,远机位登机口区域在冬季存在冷风渗透,造成室内温度低于舒适温度。在时间分布上,夏季与冬季的日内最高温度均出现在16:00时,最低温度出现在5:00时。室内CO_(2)测试浓度平均值为496 ppm,且所有测试区域均未发现有浓度超标。室内CO_(2)浓度与日旅客流量之间存在显著的线性相关性,拟合结果表明日旅客量每增加1000人,航站楼日均CO_(2)浓度上升大约5.6 ppm。室内PM_(2.5)达标率为86.8%,平均室内外浓度比值IO值为0.62。

This study selected a large terminal building as the research object and carried out long-term indoor environmental quality monitoring.The indoor thermal environment measurement shows that the ratios of PMV meeting the requirements of-1 to+1 in summer and winter were 92.9%and 92.7%,respectively.There was cold air infiltration in the remote boarding gate area in winter,which caused the indoor temperature to be lower than the comfortable temperature.The highest daily temperature in summer and winter both appeared around 4:00 p.m.,and the lowest temperature appeared around 5:00 a.m.The average indoor CO_(2) concentration was 496 ppm,and no concentration exceeding the standard was found in all areas.There was a very significant linear correlation between indoor CO_(2) concentration and daily passenger flow.The regression results show that for every 1,000 increase in daily passenger volume,the average daily CO_(2) concentration in the terminal would increase by 5.6 ppm.The indoor PM_(2.5) compliance rate was 86.8%,and the average indoor and outdoor concentration ratio was 0.62.
