中文摘要：

以自制定形相变材料（PCM）构件，与EPS板组成相变-保温复合结构，在升温-降温过程中，测试了该结构的温度-时间响应。结果表明：加入PCM构件与多层EPS板形成相变-保温复合结构后，系统热惰性显著提高。其中PCM在第2层或第3层位置时，较之标准实验结果，升温用时和降温用时分别延长了12倍和6倍，而在第4层时相变过程不够充分。从最内层的温度-时间响应看，PCM在第3层时蓄热保温效果最好，并以简化的等效热流图对此进行了分析。若将此定型相变材料制成板片状结构嵌入外墙保温材料内适当位置蓄热保温，可增强墙体热惰性，达到建筑节能目的。

英文摘要：

A composite shape-stabilized phase change material （called PCM） was made and shaped into a flake. A composite configuration was made up by adding the PCM flake inside to substitute a different layer of multiple EPS flakes. The temperature-to-time response of this configuration was tested when heated it under a stable temperature and cooled it in air to the room temperature. The result shows that the composite configuration has a much higher thermal inertia than that of EPS flakes without PCM （regard as standard result）. And when PCM flake is at the second or third layer, the time taken to heat and cool multiplied 12 and 6 times respectively compared to the standard result. While PCM flake is at the fourth layer, it does not take a full phase change course. Considered the temperature-to-time response result of the last-and-fifth layer, PCM flake at the second layer had a best capacity to store thermal energy and preserve heat, wtlich is also testified by a simple equivalent heat-flow-chart of the system. Applying the shape-stabilized PCM flake into insulation material inside wallboard at a proper position will store thermal energy and preserve heat to increase the thermal inertia, which can conserve energy in buildings.
