摘要:
玻璃围护结构蓄能特性直接影响其热工性能,其与材料本身有关.传统玻璃围护结构热惰性小、传热系数大特点,造成建筑能耗较大,并对室内热环境造成一定的影响.以玻璃围护结构蓄能特性调控为研究目标,建立了填充多种材料玻璃围护结构建筑热分析模型,分析了玻璃腔内置空气、二氧化硅气凝胶、相变材料对玻璃围护结构蓄能特性的影响,并研究了其对室内热环境的影响.研究发现:玻璃围护结构添加相变材料时蓄能和热惰性更强; 同填充二氧化硅气凝胶、空气相比,相同室内外环境条件下玻璃围护结构添加相变材料时内表面温度分别降低1.50 K和3.54 K,内表面峰值热流分别降低1.26 W·m-2和2.62 W·m-2; 玻璃围护结构添加相变材料能有效改善室内温度分布均匀性和室内热舒适性.
Abstract:
The thermal performance of glass envelope is directly affected by its energy storage characteristics, which depends on the properties of materials. Traditional glass envelope has the characteristics of small thermal inertia and large heat transfer coefficient, which leads to large building energy consumption and poor indoor thermal environment. Taking the regulation of energy storage characteristics as the research objective, a thermal analysis model of glass envelope building is established, and the influence of different materials including air, silica aerogel and phase change material on energy storage characteristics and indoor thermal environment is analyzed. The results show that the energy storage and thermal inertia are stronger when phase change materials are added to the glass envelope. Compared with glass envelope filled with silica aerogel and air, when phase change materials are added, the inner surface temperature decreases by 1.50 K and 3.54 K, respectively, and the peak heat flux on the inner surface decreases by 1.26 W·m-2 and 2.62 W·m-2, showing that glass envelope with phase change materials can effectively improve indoor temperature distribution uniformity and indoor thermal comfort.
