哈尔滨冬季高校教室IAQ及热舒适现场研究

为了研究适于寒地教室建筑室内空气品质(IAQ)和室内人员热舒适指标及探讨改善措施,本文对哈尔滨市6所高校23个教室的IAQ和热环境进行了现场调查研究,得到有效问卷623份。在此基础上利用线性回归方法建立了冬季教室环境下的热感觉方程,得到了该环境下学生的热中性温度,发现低于哈尔滨居民的热中性温度;且受试者在较低或较高CO2浓度下都不能对IAQ做出合理的主观判断。同时,分析结果表明,哈尔滨教室冬季IAQ普遍较差,热量浪费严重,亟需有效的改善措施,并加强相关知识的宣传教育。

Field Study on IAQ and Thermal Comfort of University Classrooms in Winter of Harbin

In winter, A field study of indoor air quality and thermal comfort in 23 classrooms of 6 universities in Harbin, for the study and amelioration of classrooms IAQ and thermal comfort in cold area of China. 623 sets of questionnaire responses were obtained. The thermal sensation equation in the elassroores in winter has been built through linear method, computed the neutral temperature of students, and it lower than the neutral temperature of occupants in Harbin. There will be unreasonable assessments which testers make, whether the CO2 concentration is higher or lower. The results show that, The IAQ of classroom is very bad in winter of Harbin, and the waste of energy is serious. It is essential to obtain effective methods to ameliorate IAQ and energy waste, and improve the knowledge of people about it.
