摘要
Abstract
In order to study melting and solidification temperature range of thermal storage material sodium acetate trihydrate in the energy storage project, melting experiments under different bath temperatures and solidification experiments under different cooling were implemented, and related parameters of phase change heat storage properties were obtained. The experimental results show that the supercooling degree of thermal storage material has an increasing trendency when the heating bath temperature decreases. The phase change properties are stable when the bath temperature is within 83 ℃, and the performance cannot be guaranteed when the bath temperature is above 83 ℃. The lower the cooling temperature is, the greater the supercooling degree. But as long as cooling in air bath or water bath in normal circumstance, even if the cooling environment temperature changes greatly, the phase change heat storage properties will be stable all the same.关键词
