摘　　要：使用合适的储热材料可以提高热功转换的效率,实现热量的高效利用。由于相变材料可以利用潜热储热,储热密度相对较大,因此利用相变材料储热成为研究热点。该文对近年来储热用相变材料的特性研究进行概述,主要是有机和无机相变材料的改性进行对比研究,确定改性方法,并进一步梳理目前国内外针对储热材料的研究方向及储热项目,总结得出现有大型储热项目主要还是采用显热蓄热材料,相变储热材料的推广应用尚待进一步开发。The use of suitable heat storage materials can improve the efficiency of heat work conversion and realize the efficient utilization of heat.Because phase change materials can use latent heat to store heat,and the heat storage density is relatively high,so the use of phase change materials for heat storage has become a research hotspot.This paper summarizes the research on the characteristics of phase change materials for heat storage in recent years,mainly the comparative study on the modification of organic and inorganic phase change materials,and determines the modification methods.and further sort out the current research direction and heat storage projects of heat storage materials at home and abroad,it is concluded that the existing large-scale heat storage projects mainly use sensible heat storage materials,and the promotion and application of phase change heat storage materials need to be further developed.
