Abstract


Higher quality of indoor thermal environment is directly related to the student 's learning efficiency as well as physical and mental health , in order to study Harbin University of indoor thermal environment , this paper a university in Harbin classrooms, libraries , for example, using on-site tests and questionnaires approach from both objective and subjective analysis of the heating period, the university building indoor thermal environment . Clothing thermal resistance in the subjects for statistical analysis found that Southerners clothing thermal resistance rate of change with the operating temperature is greater than the northerners , the room temperature is higher than 23.7 ℃ , the southerners should be less than the amount of clothing in northern people . By KS test subjects that may affect the value of thermal sensation votes related parameters were analyzed and found that gender, geography and indoor temperature on the thermal sensation votes subjects had significant impact on the value . 80% of the actual surveys acceptable temperature range of 19.6 ~ 24.4 ℃, this comfort zone is recommended 19.6 ~ 22.5 ℃. Through the indoor temperature and the desired temperature neutral comparison found that the neutral temperature is higher than the desired temperature value, and northerners neutral temperature and the desired temperature value is higher than the value of southerners under the same conditions . Through testing and questionnaire analysis to find the contrast between the measured college indoor thermal environment problems , and the corresponding improvement measures.
