三水合醋酸钠的相变贮热性能

Phase Change Property of Sodium Acetate Trihydrate as Heat Storage Material

    摘要
  • 摘要: 以三水合醋酸钠（CH3COONa·3H2O）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252J/g,潜热大,贮热性能稳定。

     

    Abstract: 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.
