摘　　要：简单介绍了无机水合盐CH3COONa.3H2O用作相变储热材料时的优缺点,针对其存在过冷和相分层问题,目前研究所得的解决方法是添加增稠剂和成核剂。综述了分别添加增稠剂、成核剂及同时添加时对CH3COONa.3H2O相分层和过冷抑制的研究进展,分析了不同的添加剂和添加量对抑制作用的不同以及温度影响添加剂抑制作用的原因,最后指出了CH3COONa.3H2O今后主要的研究方向。It is a brief introduction of advantages and disadvantages of the inorganic hydrated saltCH3COONa·3H2O as a phase change meterial for thermal energy storage. Up to now, the solution is to add thickener and nucleating agent to the problems of supercooling and phase stratification issues. The research progress is reviewed when adding thickener and nucleating agent respectively, and adding them together for affecting the inhibition of phase stra- tification and supercooling of CH3COONa·3H2O. The reason that the different inhibitions caused by different additives, addition amount and the temperature influencing the inhibition of additive is analyzed. At last the main research directions of CH3COONa·3H2O in future are pointed out.
