超薄、轻质等材料建造的房屋在救灾、建筑工地领域应用普遍,针对这类特殊建筑的温室效应现象虽有揭示,但局限于透光膜及玻璃房,对其冷室效应认识尚属空白。本文通过搭建外形尺寸相同、围护材料材质不同的超薄轻质围护结构模型建筑,在相同的室外条件下进行对比实验,发现无论夏天或冬天,在有太阳辐射的白天时刻,即使非透光的超薄轻质围护结构建筑的室内表面温度和气温均高于或远高于室外温度,温室效应的强度取决于室外气候条件和围护结构特性;在夜晚,室内表面温度和气温可能低于室外温度,超薄围护结构比轻质围护结构的冷室效应显著,晴朗夜晚比阴雨夜晚显著,并进一步揭示这类建筑的特殊热环境现象的共性规律和形成机理。
Slim and light materials are widely used in disaster relief and construction sites. Although the greenhouse effect for such special buildings has been revealed, it is limited to light-transmissive film and glass house, blank. In this paper, by building an ultra-thin light-weight building structure with the same exterior dimensions and different covering materials, under the same outdoor conditions, comparative experiments were conducted to find that in summer or winter, when there is solar radiation daylight, Light ultra-thin lightweight envelope structure of the indoor surface temperature and air temperature are higher or higher than the outdoor temperature, the intensity of the greenhouse effect depends on the outdoor climate and envelope structure characteristics; at night, the indoor surface temperature and temperature may Below the outdoor temperature, the effect of the cold room of the ultra-thin envelope structure is more significant than that of the lightweight envelope structure. The clear night is more pronounced than the overcast night and reveals the common law and formation mechanism of the special thermal environment phenomenon of such buildings.
