摘要

以六水氯化钙为基材,配备出一种新型复合相变蓄冷材料用于空调蓄冷。该材料的质量配比为81%六水氯化钙+5%乙醇+14%丙三醇。为了降低复合相变材料的过冷度,使用六水氯化铯为成核剂,发现成核剂的添加量为1.0%时过冷度几乎为零。为检验复合相变材料的热稳定性,进行了100次的热循环实验,材料未出现相分层,表明其热稳定性能良好。

Abstract

With CaCl₂·6H₂O as the base material,a new type of composite phase change cold storage material was prepared for air-conditioning cold storage.The mass ratio of the material was 81wt.% calcium chloride hexahydrate+5wt.% ethanol+14wt.% glycerol.In order to reduce the undercooling of composite phase change materials,cesium chloride hexahydrate was used as nucleating agent.It was found that the undercooling was almost zero when the amount of nucleating agent was 1.0wt.%.Aiming to test the thermal stability of the composite phase change material,100 thermal cycling experiments were carried out,and the material did not show phase stratification,indicating that its thermal stability was good.
