桂林高校宿舍冬夏两季室内热舒适研究

Research on indoor thermal comfort in winter and summer in Guilin university dormitories

对桂林某大学的学生宿舍冬夏两季室内外空气温湿度、室内空气流速等参数进行现场测试,运用问卷的形式对学生的服装情况及对室内热环境的主观感受进行调查,对测试和调查结果进行统计分析。结果显示,冬季实测和预测中性温度分别为19.7℃和18.6℃;夏季实测和预测中性温度分别为26.6℃和27.7℃。在满意度为80%时,实测与预测可接受全年操作温度分别为14~29℃和13.7~31.2℃。结合影响宿舍热舒适的主要因素,从节能角度提出适宜性的改善措施,为该地区高校学生宿舍室内热环境的改善和制定室内热舒适设计标准提供参考。

The parameters of indoor and outdoor air temperature and humidity,indoor air velocity and other parameters in the student dormitory of a university in Guilin in winter and summer were tested on the spot,and the students'clothing and subjective feelings of the indoor thermal environment were investigated in the form of questionnaires,and the test and survey results were statistically analyzed.The results showed that the measured and predicted neutral temperatures in winter were 19.7℃and 18.6℃,respectively.The measured and predicted neutral temperatures in summer were 26.6℃and 27.7℃,respectively.When the satisfaction rate is 80%,the measured and predicted acceptable annual operating temperatures are 14~29℃and 13.7~31.2℃,respectively.Combined with the main factors affecting the thermal comfort of the dormitory,this paper puts forward the improvement measures of suitability from the perspective of energy saving,so as to provide a reference for the improvement of the indoor thermal environment of the dormitory of colleges and universities in the region and the formulation of indoor thermal comfort design standards.
