严寒地区某高校体育馆室内热环境研究

Study on the indoor thermal environment of a college gymnasium in a severe cold region

采用现场测量和问卷调查的方法对严寒地区某高校体育馆比赛场地及观众席的室内热环境进行了研究。通过测量体育馆室内空气的温度、相对湿度、CO_(2)含量等,对数据进行整理分析,得到体育馆温度在21℃~23℃高于标准值;供暖前后甲醛含量、TVOC含量和CO_(2)浓度均符合标准;昼间平均噪声为53 dB,小于55 dB(国家规范);40%的被调查人员认为体育馆较暖;适当的通风能有效改善室内热环境和提高人体热舒适性。通过计算PMV,PPD,按照国家规范分析体育馆室内热环境舒适度,为严寒地区体育馆室内热湿环境的改进提供参考依据。

The indoor thermal environment of the playing field and spectator stand of a university gymnasium in a severe cold region was studied by using on-site measurements and questionnaires.By measuring the temperature,relative humidity and CO_(2) content of the indoor air in the gymnasium and organizing and analyzing the data,it was obtained that the temperature of the gymnasium was higher than the standard value at 21℃~23℃;the formaldehyde content,TVOC content and CO_(2) concentration before and after the heating were in line with the standard;the average noise during daytime was 53 dB which was less than 55 dB(the national specification);40%of the investigated people thought that the gymnasium was warmer;and the proper ventilation can effectively improve the indoor thermal environment and enhance human thermal comfort.By calculating PMV and PPD,the comfort of indoor thermal environment in gymnasiums is analyzed according to the national norms,which provides a reference basis for the improvement of indoor thermal and humid environment in gymnasiums in severe cold regions.
