低温相变蓄热材料研究进展

State-of-the-art of PCMs for Heat Storage at Low Temperature

蓄热技术是解决能源危机的重要手段之一,相变温度在60～80℃范围内的蓄热材料被广泛应用于太阳能储存、工业废热回收、电子器件热管理以及供暖和空调系统等领域。本文介绍了常用的可作为相变材料(PCMs)的有机物和无机物,探讨了复合相变材料的制备方法,分析了该类型相变蓄热材料的应用现状及发展前景。

Thermal energy storage （TES） technique is a most important measure to deal with the energy crisis, and phase change materials （PCMs） which melt between 600℃ and 800℃ in particular have been widely used for storing solar energy, reclaiming waster industry heat, thermal managing of electronic devices, heating, air-conditioning and other fields. In this paper, main types of organic and inorganic phase change materials in common use have been introduced, the means of making compound PCMs were discussed, the variety application of these materials were presented, and some prospective development of PCMs were anticipated.
