摘　　要：为解决寒冷地区冬季自然通风状态下高校教学建筑室内的空气品质问题,对西安某高校13个自然通风教室内/外温湿度、CO_(2)质量浓度、风速等参数进行监测,同时记录了698名学生对室内温湿度和空气品质的主观评价。结果表明:冬季学生群体平均服装热阻为1.29 clo,室内热中性温度为20.7℃;被测教室室内除湿度外,温度和CO_(2)质量浓度均不符合我国室内空气质量标准要求。结合学生对室内空气质量的评价,得出未合理使用门窗进行通风,导致室内空气不流通,学生对感知上课期间整体环境的舒适度以及满意度均较低,且伴随犯困、皮肤干燥、注意力下降、情绪压抑等症状。In order to solve the problem of poor indoor air quality in teaching buildings of natural ventilation colleges and universities in cold areas,the temperature and humidity,CO_(2) concentration,wind speed and other parameters of 13 natural ventilation classrooms in a university in Xi’an were monitored.At the same time,698 students′subjective evaluation of indoor temperature,humidity and air quality were recorded.The results show that the average clothing thermal resistance in winter is 1.29 clo,and the indoor thermal neutral temperature is 20.7℃.Except for the humidity,the temperature and CO_(2) concentration in the tested classroom do not meet the requirements of national indoor air quality standards.Combined with the students′evaluation of indoor air quality,it is concluded that the unreasonable use of doors and windows for ventilation has led to poor indoor air circulation,the overall environment comfort degree and satisfaction level the students percieved during class is low,such as by drowsiness,dry skin,decreased concentration,and emotional depression.
