摘要
相变材料具有高效的能量储存功能。相变材料与建材基体结合，制成一种具有储热功能的围护结构。该围护结构可发挥相变储热功能，降低建筑室内温度波动，增强建筑热舒适度，能够更加有效地减少建筑物运行能耗，从而实现建筑节能。本文对当前现有相变材料的优缺点、相变材料在不同围护结构中的应用、相变储能围护结构对室内热环境的影响及对建筑运行能耗的影响、相变储能围护结构应用的经济性等方面进行了分析，提出相变储能围护结构在工程应用中所存在的不足及其发展前景。
Phase change materials have high efficiency in energy storage. The phase change material and the building material matrix are combined to form a kind of heat storage enclosure structure. This enclosure structure can play the function of phase change heat storage, reduce the fluctuation of indoor temperature, enhance the thermal comfort of the building, and reduce the energy consumption of the building operation more effectively, thus realizing the building energy saving.In this paper,the advantages and disadvantages of current existing phase change energy storage materials,the application of phase change materials in different enclosure structures,the influence of phase change energy storage enclosure on indoor thermal environment and its influence on energy consumption of building operation,the economy of phase change energy storage enclosure＇s application and so on were analyzed,the disadvantages and prospects for development of phase change energy storage enclosure in engineering application are presented.
