中文摘要：

以三水醋酸钠（CH3COONa·3H2O）为蓄热基质，通过大量实验，遴选合适的抗沉淀剂和成核剂，配成相变温度约55℃、过冷度小于2℃的蓄热材料。对该材料的蓄热性能进行研究表明，该材料相变热可达238J／g，导热系数为1．072W／m·K（30℃时），可用于空调冷凝热回收系统。

英文摘要：

A new heat storage material （CH3COONa·3H2O） with a phase change temperature of 55℃ and a sub-cooling temperature of less than 2 ℃ was developed. This sodium acetate trihydrate based material was obtained by a number of experiments for selecting proper nucleation catalysts and suspension mediums. The study results indicate that its fusion heat and thermal conductivity is 238J/g and 1.072W/m·K （at 30℃）, respectively. It seems that this new material may be suitable for heat storage in air conditioning systems.
