成都某高校教室夏季热舒适调查研究

摘要

Tests the indoor temperature, relative humidity and air velcity in the college classrooms in June of Chengdu. Surveys the subjective assessment of students on the indoor and outdoor thermal environment by questionnaires. The results show, 71.8% of the students accept the thermal sensation in this period; the thermal neutral temperature is 25.96℃and the therm preferred temperature is 25.89(℃~,27 th.2e6 thermal comfort temperature range℃ o,f t 8h0e% up ipse 2r5 l.i4m )with the recommended classroom design temperature limit in ISO7730 standard; thermal sensation of the actual test is more sensitive than thermal sensation of PMV prediction in the classroom, and thermal sensation of in the classroom is more sensitive than thermal sensation of the residence.%以6月份成都某高校教室为研究对象,在开窗通风和可自由开启吊扇的条件下,现场测试了教室内的温度、相对湿度和风速等参数,通过问卷调查了学生对室内外热环境的主观热感觉,并与本地住宅和国内其他城市同类建筑的研究成果进行了比较.结果表明:71.8%的学生对该时段内的热感觉表示接受;热中性温度为25.96℃,热期望温度为25.89℃,热舒适温度范围为25.44~27.26℃,与ISO7730标准中提供的教室推荐设计温度上限基本一致;另外,教室中测试拟合的TSV斜率大于PMV斜率,表明对温度的敏感性,学生实际的感觉比PMV预测的变化要快,并且人员在教室中比住宅中对温度的变化感觉更灵敏.
