摘要
以三水合醋酸钠 (CH3COONa·3H2 O)为贮热基质 ,评选和优化成核剂和抗沉淀剂 ,组成贮热介质工作温度约 60℃和过冷度小于 5℃的贮热材料。经DSC法测定和计算 ,该贮热材料的熔解热可达 2 5 2J g ,潜热大 ,贮热性能稳定。
A heat storage material with phase change temperature 60℃ and supercooling temperature less than 5℃ is developed. The material is composed of sodium acetate trihydrate, nucleators and suspension mediums. The fusion heat of the material is 252J/g measured by DSC and the property of heat storage is stable.
