重庆地区冬季教室热环境调查分析
Investigation and analysis on classroom thermal environment in winter in Chongqing
摘要：
测试了重庆地区冬季教室内的干湿球温度、空气流动速度等热环境参数，用ASHRAE七级热感觉标尺进行了热舒适问卷调查，提出了改善教室内热环境的措施。分析了预测平均投票PMV与实际平均投票AMV之间的差异，得出重庆地区冬季教室内可接受温度下限为14.04 ℃的结论。

Abstract：
Tests the thermal environment parameters of classrooms including the dry/wet bulb temperatures and air velocity and investigates the thermal comfort status using ASHRAE seven sensation scales by questionnaires. Suggests some measures to improve classroom thermal environment. Analyses the difference between the predicted mean votes and the actual mean votes, and proposes that the lower limited scope of classroom acceptable temperature in winter in Chongqing is 14.04 ℃.
