摘　　要：以桂林市某高校教学楼第3层的4间教室为研究对象,对冬季室内热环境和学生的热舒适性感觉进行为期两天的直接测量和问卷调查,并对结果进行分析。结果表明:桂林高校教室冬季普遍温度过低且相对湿度较大,室内引入的新风量少、闷感强烈导致热环境较差;大部分学生对环境具有一定的适应能力,通过采取一些适应性行为调节自身的热舒适程度;桂林高校教室非空调环境下,冬季中性温度为19.9℃,期望温度为20.7℃。Taking four classrooms on the third floor of a teaching building in a university in Guilin as the study object,the indoor thermal environment and thermal comfort feeling of students in winter were directly measured and investigated by questionnaire for two days and the results were analyzed. The results show that the classroom temperature in Guilin university is generally too low and the relative humidity is high in winter, and the indoor fresh air volume is less and the stuffy feeling is strong, which leads to the poor thermal environment. Most students have certain adaptability to the environment and will take some adaptive behaviors to adjust their thermal comfort degree. In the non-air-conditioned environment of classrooms in Guilin universities, the neutral temperature in winter is 19.9 ℃, and the preferred temperature is 20.7 ℃.
