为研究冬季大学生上课期间的室内热环境和热舒适状况,对兰州市某高校22间教室的室内空气干球温度、相对湿度、风速等热环境参数进行了现场测试,同时以问卷方式对ASHRAE的7级热舒适指标进行了调查。结果表明,84.8%的学生对室内19.7℃的平均温度表示接受,热中性温度为19.3℃,所期望的温度为20.8℃;80%的人感到舒适的温度范围为18.2～22.2℃,该结果的上、下限均比ASHRAE推荐的80%人群可接受温度为21～24℃的要求低约2℃。不同地区的室内人体热感觉存在差异,该研究结果可为兰州室内环境的控制和制定合适的教室内热环境标准提供参考。
In order to study the indoor thermal environment and thermal comfort status of winter college students in class, a field test was conducted on the thermal environmental parameters such as indoor air dry bulb temperature, relative humidity and wind speed of 22 classrooms in a university in Lanzhou. At the same time, questionnaires were conducted on ASHRAE 7 thermal comfort indicators were investigated. The results showed that 84.8% of the students accepted an average indoor temperature of 19.7 ℃, the temperature was 19.3 ℃, the expected temperature was 20.8 ℃; 80% of the people felt comfortable temperature range of 18.2-22.2 ℃, the result The upper and lower limits are both about 2 ° C lower than the acceptable temperature of 21 to 24 ° C for the 80% of the people recommended by ASHRAE. Indoor heat sensation in different areas is different, and the results of this study can provide reference for the control of indoor environment in Lanzhou and the establishment of suitable indoor thermal environment standards.
