| 摘 要： | 对哈尔滨市某办公建筑的房间利用夜间通风改善室内热环境进行了实验研究,实验中连续测试了室内、室外空气的干球温度,同时测试了墙体内表面温度和室内空气温度、相对湿度.结果表明:对北向房间(房间1、2)利用夜间通风每天可以少开空调2.75 h,则最大可节约电量4.95 kW h/d.对整个办公楼,平均节约空调运行电费0.073元/m2?d.并确定了夜间通风的原则.

| Abstract: | An experimental study on night ventilation was carried out in Harbin to improve thermal environment in office rooms.Some physical data were measured continuously,such as indoor air temperature and outdoor air temperature.At the same time,the relative humidity and surface temperature were tested.The results showed that for the northern office rooms,the length of operation time of air conditioner was reduced by 2.75 hours per day,with using night ventilation technology.And thus the energy could be saved 4.95KWh per day.The operation fees could decrease 0.073 yuan per square meter per day for the whole office building.And the principle of night ventilation was given. |
