对相变材料在墙体中的封装方式（直接混合、宏观封装、微观封装和定形相变材料封装）、相变材料的种类和物性等方面的研究进行了归纳总结。从实验和模拟2个方面，对相变材料位于墙体表面和墙体内部影响室内环境和建筑能耗的研究进行了综述和评价。分析表明，微观封装和定形相变材料的封装效果较好；墙体用相变材料的相变温度一般在20～30℃范围内；相变材料层在墙体中的安装位置可分为墙体表面和墙体内部2种，但相变材料层在墙体内的最优位置并不固定，受相变材料物性、墙体材料以及室内外环境工况的影响。通过相变材料与墙体合理高效的结合，可充分发挥相变材料的高蓄热特性，提高墙体的热性能，达到调节室内环境温度、降低建筑能耗的目的。

The encapsulation methods for phase change materials ( PCMs) in building walls inclu-ding direct-mixing, macro-encapsulation, micro-encapsulation, and shape-stabilized PCMs, the kinds of PCMs and their properties are reviewed.The PCMs can be located at the wall surface or in-side the wall, the effects of PCMs in both cases on the indoor environment and building energy con-sumption are evaluated respectively based on experiments and simulation research.The results show that the encapsulation effects of the micro-encapsulation and shape-stabilized PCMs are better.The phase change temperatures of PCMs used in the building walls are usually 20 to 30 ℃.The optimal location of PCMs is not fixed.It is affected by the properties of PCMs, wall material, indoor envi-ronment and outdoor environment.By integrating PCMs with the building walls effectively, the high thermal storage property of PCMs can be fully developed and the thermal performance of the building walls is improved.Thus, the indoor air temperature is adjusted and the building energy consumption is reduced.
