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.
