摘要
无机水合盐相变储能材料通常存在过冷现象,影响了该类材料所蓄热量的排放性能,如果过冷严重,储存的热量不能释放出来。就无机水合盐的过冷机理及非均匀形核的动力学机理进行了探讨,加入成核剂是降低过冷度的有效措施。
Salt hydrates are used as thermal energy storage materials. The supercooling of these materials, which is generally present during extraction of the stored heat, reduces the utility of the materials and, if too severe, can completely prevent heat recovery. This paper discusses the nucleating mechanisms of the salt hydrates and comes to the conclusion that adding suitable nucleating agents reduces significantly the degree of supercooling.
