八水氢氧化钡在热仓供暖中的应用

Application of Composite Barium Hydroxide Octahydrate in Thermal Storage Heating System

通过步冷曲线法与差式量热扫描法研究了以八水氢氧化钡为主要原料的复合相变材料的相变性能。并在60 MJ的热仓供暖实验系统中,对其蓄热性能进行了实验。实验表明,采用八水氢氧化钡蓄热的供暖热仓,有良好的蓄热能力,充热完成后,放热时间长达6.5 h以上,预计可以提供0.45吨以上的生活热水。采用移峰填谷的充放热模式,在实现能量的调配的同时,满足日常供暖的需求。

The composite barium hydroxide octahydrate was applied to a 60 MJ thermal storage heating experiment system,and the phase change performance was studied by step cooling curve method and differential calorimetry scanning method.The experiment results showed that modified phase change material had good heat storage capacity.The heat release time can reach more than 6.5 h,and it was expected to provide more than 0.45 tons of domestic hot water after the heating was completed.The peak-filling and valley-filling heat-dissipation mode was adopted to meet the needs of daily heating while achieving energy allocation.
