太阳能蓄热技术研究进展

Research and Development of Solar Energy Thermal Storage Technology

太阳能蓄热根据储热机制的不同可分为显热蓄热、潜热蓄热与化学蓄热。介绍了三种蓄热方式的研究现状与各种蓄热材料的优缺点,并且对比分析了三种蓄热方式的特性。其中潜热蓄热,特别是相变材料的蓄热技术应用最为广泛;显热蓄热如混凝土蓄热技术目前正在研究之中;化学蓄热则在实验阶段。

According to the mechanism of the heat thermal storage,it can be divided into sensible heat thermal energy storage,the latent heat thermal storage and chemical heat storage.This paper introduced three methods of heat storage and comparatively analyses the advantages and disadvantages of different heat storage materials.Latent heat thermal storage such as phase change materials is the most widely used storage technology,while the sensible heat thermal storage such as concrete storage technology currently under study,the chemical heat storage is still experimental.
