重庆某高校学生公寓夜间通风实验研究
Experimental study on night ventilation for university student dormitories in Chongqing
摘要：
针对7个室内布局基本相同的房间进行了夜间通风的实验研究，分析了不同天气状况、不同建筑朝向、不同阳台门开启度及不同控制方案条件下，夜间通风对学生公寓的降温效果。实验结果表明：阴天室内夜间温度降幅最大可达0.5 ℃，晴天降幅最大可达0.6 ℃；换气次数越大、通风时间越长，夜间通风的降温效果越明显；在夏季多阴雨天气的重庆地区，大力推广夜间通风降温技术，且使空调系统与夜间通风合理地联合运行，有利于实现建筑节能。
Abstract：
Taking seven rooms with the same layout as the example, carries out experimental studies on night ventilation. Studies the cooling effect of the night ventilation on student dormitories under different conditions including weather, building orientation, open degree of balcony door and control scheme. The results show that indoor temperature drops at night can reach up to 0.5 ℃ in rainy day and 0.6 ℃ in sunny days. Increasing air change rate and ventilation time is effective measure to improve the night ventilation efficiency. Night ventilation should be vigorously promoted in rainy summer in Chongqing. Besides, the reasonable operation of air conditioning system combined with night ventilation is conducive to building energy efficiency.
