桂林某高校图书馆冬季室内热环境与热舒适性研究

Winter thermal environment and comfort research for a university library in Guilin

对桂林市某高校图书馆冬季室内热环境和学生的热舒适进行为期10天的现场主观问卷调查和室内外环境参数测试,并对结果进行线性回归分析。结果显示,冬季图书馆内平均温度和热中性温度分别为19.9、19.7℃,受试者满意度为83.1%;PMV模型预测热中性温度为23.4℃,与MTS计算值之间存在3.7℃的温差;操作温度可接受范围为13.7~25.7℃;受试者通过服装调节、心理期望等方式适应偏冷的热环境。

A field study on winter indoor thermal environment and thermal comfort was carried out in a library of a university in Guilin for ten day by subjective questionnaires. Indoor and outdoor environmental parameters were measured and the data was analyzed with linear regression. The results show that the average air temperature and thermal neutral temperature are 19.9 ℃ and 19.7 ℃ respectively, and the satisfaction rate reaches to 83.1%.The predicted thermal neutral temperature of PMV model is 23.4 ℃,and there is a difference of 3.7 ℃ with the calculated MTS. The acceptable operative temperature ranges from 13.7 ℃ to 25.7 ℃.Subjects get accustomed to the thermal environment by clothing adjustment and psychological acclimatization, etc.
