Abstract

The salt hydrate heat storage phase change material (PCM) has a promising prospect of application and has become a research hotspot because of the advantages of high thermal storage density, high thermal conductivity, moderate phase change temperature, and low price. However, some problems have restricted the application of salt hydrate heat storage materials, such as phase separation, supercooling, and corrosion of the metal container. A microencapsulated PCM using the microencapsulated technology of solid PCM coated packaging with core-shell structure composite material is an effective method to solve the above problems. In this paper, the research situations involving microencapsulated salt hydrate are analysed. This review introduces the selection of core and shell materials, compares the different preparation methods of encapsulated salt hydrate PCMs and summarizes the application fields.
包封盐水合物核壳相变材料研究进展
盐水合物储热相变材料(PCM)因其储热密度高、导热系数高、相变温度适中、价格低廉等优点,具有广阔的应用前景,成为研究热点。然而,盐水合物储热材料存在相分离、过冷、金属容器腐蚀等问题,制约了盐水合物储热材料的应用。采用核壳结构复合材料包覆固体PCM封装的微胶囊化技术实现PCM微胶囊化是解决上述问题的有效方法。本文分析了微囊化水合盐的研究现状。本文介绍了芯壳材料的选择,比较了包封盐水合物PCMs的不同制备方法,并对其应用领域进行了总结。
