与建筑一体化脂肪酸类相变材料的研究及应用

Investigations and Applications of Fatty Acid Derivatives as Building-integrated Phase Change Materials

脂肪酸类相变材料具有良好的热物理性能、热稳定性和化学稳定性,是一类储热性能优良、易于与建筑形成一体化的有机相变材料,通过与传统的建筑材料复合可有效降低建筑能耗,起到建筑节能和调整建筑室内环境舒适度的作用。综述了脂肪酸类相变材料的研究进展及其在建筑中的主要应用情况,并对目前脂肪酸类相变材料在建筑中应用所存在的问题进行了总结。最后对其进一步的发展做了分析和展望。

Fatty acid derivatives phase change materials have good thermophysical properties, thermal and chemical stability, and are a category of organic phase change materials that possess excellent heat-storage performance as well as ease of integration with buildings. They can combine with the traditional building materials to efficiently re- duce building energy consumption and conduce to energy saving and comfortable indoor environment. The present arti- cle reviews the research progress of fatty acid derivatives used as phase change materials and their main applications in buildings, and summarizes the current issues in their building applications. Finally the further development trends are analyzed and discussed.
