衡阳地区高校学生宿舍夏季室内热环境的研究

Research on the Indoor Thermal Environment of College Student Dormitories in Hengyang in Summer

为了研究衡阳地区高校学生宿舍在夏季自然通风条件下室内的热环境与热舒适度,对衡阳地区某高校学生宿舍室内的环境参数进行现场测试,并同时对宿舍常驻学生进行了室内热湿环境的主观问卷调查。通过对调研结果分析发现,夏季自然通风条件下,宿舍室内的热感觉为热,相对湿度较高,室内通风效果不佳,63%的学生对宿舍室内的热舒适性表示不满意。利用适应性PMV模型计算得出夏季宿舍室内的热湿环境处于Ⅲ级标准,室内热环境较差。通过线性拟合得到预测平均热感觉PMV与操作温度t_(op)的关系式,研究结果得自然通风下学生宿舍夏季室内可接受温度为23.9~28.6℃,室内的热中性温度为26.3℃。

In order to study the indoor thermal environment and thermal comfort of college student dormitories in Hengyang area under natural ventilation conditions in summer,a field test was conducted on the indoor environmental parameters of a college student dormitory in Hengyang area,and the indoor thermal and humid environment for resident students Subjective questionnaire survey.Through the analysis of the research results,it is found that under natural ventilation conditions in summer,the heat in the dormitory room is hot,the relative humidity is high,and the indoor ventilation effect is not good.63%of students are not satisfied with the thermal comfort of the dormitory room.The adaptive PMV model is used to calculate that the heat and humidity environment in the summer dormitory is at the level Ⅲ standard,and the indoor thermal environment is poor.The relationship between the predicted average thermal sensation PMV and the operating temperature t_(op) is obtained by linear fitting.The results of the study show that the acceptable indoor temperature of the student dormitory under natural ventilation is 23.9~28.6℃,and the indoor thermal neutral temperature is 26.3℃.
