【摘要】：为了分析传统民居夏季室内热环境现状特点及形成机理,对徽州传统民居夏季室内的空气温度、湿度、壁面温度、风速进行实测。通过对实测数据的分析发现,传统民居的夏季隔热、通风效果优于现代民居。传统民居各功能区域低于热舒适区上限温度的时间频率均高于85%,但湿度较高,夏季热环境良好。阁楼夏季的热缓冲层效果明显,传统民居坡屋顶及屋面构造、空斗砖墙构造对于夏季隔热效果显著。此外,天井热压通风量夜间大于日间,夜间通风是带走室内热量的重要手段。白天围护结构隔热,夜间天井通风是徽州传统民居营造夏季室内环境的被动式策略。
[Abstract]:In order to analyze the characteristics and formation mechanism of indoor thermal environment in summer, the indoor air temperature, humidity, wall temperature and wind speed of Huizhou traditional dwellings in summer were measured. Through the analysis of the measured data, it is found that the heat insulation and ventilation effect of traditional dwellings in summer are better than those of modern dwellings. The time frequency lower than the upper limit temperature of the thermal comfort zone in each functional area of traditional dwellings is higher than 85%, but the humidity is higher and the thermal environment is good in summer. The effect of thermal buffer layer of attic in summer is obvious. The slope roof and roof structure of traditional dwellings and the structure of empty bucket brick wall have remarkable effect on heat insulation in summer. In addition, the ventilation volume of hot pressing in patio is larger than that of day at night, and night ventilation is an important means to take away indoor heat. It is the passive strategy of traditional residence in Huizhou to build indoor environment in summer by heat insulation of day enclosure and ventilation of patio at night.
