夏热冬冷地区典型学生宿舍夏季室内空气环境的研究

Study on the Summer Indoor Air Environment of Typical University Dormitory Buildings in Hot Summer and Cold Winter Zone

对夏热冬冷地区典型学生宿舍建筑自然通风条件下的夏季室内空气环境进行了连续7d实测和问卷调查,分析了不同朝向房间的室内空气环境特征.结果表明,夏季自然通风条件下,尽管夜间室内热环境略好于昼间,但温度均高于26℃;由于室内通风好,房间内热湿环境仍处于多数学生可以接受的范围内,室内空气品质好;另外,太阳辐射对房间内温度分布有重要影响,南向房间平均温度高出北向房间约0.8℃,昼间两者最大温差达2.6℃.

The summer indoor air environment of typical university dormitory buildings under natural ventilation in hot summer and cold winter zone was studied through a 7-day continuous field measurement and questionnaire survey, and the characteristic of indoor air environment of rooms with different orientations was analyzed. The results show that though the indoor thermal environment of the naturally ventilated rooms during the sleeping hours at night is comparatively better than that during the day, the indoor temperature is all above 26 ~C. Due to the effective ventilation of the room, the indoor thermal and humidity environment is in the range that most of the students can accept, and the indoor air quality is good. In addition, solar radiation has significant influence on the indoor air temperature of different rooms, the indoor temperature of south-facing rooms is O. 8℃ higher than that of the north-facing rooms in average, and the maximum temperature difference in the daytime may reach 2.6 ℃.
