以南京地区高校学生公寓为研究对象,进行了问卷调研和夏季室内空气温度、相对湿度、风速等环境参数进行了测试,获得了有效问卷539份.采用ASHRAE的七级热感觉标度对受试者热感觉主观反映进行统计.采用BIN法将各组间作业温度与平均热感觉进行线性回归分析,得到热中性温度为26.8℃,自然通风环境下夏季80%可接受的温度域为24.5℃~29.3℃.研究成果可为南京地区高校建筑自然通风环境下的热舒适研究提供参考,为进一步完善南京高校建筑热舒适标准及节约能耗提供科学依据.%Taking the college apartment in Nanjing as the research object, we conducted about questionnaire investigation on thermal comfort, and tested the environment parameters which included indoor air temperature, relative humidity. We received 539 valid questionnaires. By adopting seven thermal sensation scale of ASHRAE standard, we counted subjective thermal sensation of subjects. Temperature frequency method has been used to move linear regression analysis between each operation temperature and the average thermal sensation in each group, we obtained hot neutral temperature is 26.8℃, 80% acceptable temperature range under natural ventilation environment summer is from 24.5℃ to 29.3℃. Then we analyzed differences between predicted thermal sensation (PMV) and mean thermal sensation (MTS) under natural ventilation environment. These research results can provide reference for thermal comfort study of college buildings under natural ventilation environment in Nanjing, and further to improve thermal comfort standard and a scientific basis for saving energy consumption for university buildings in Nanjing.
