摘要
通过实验分析了空调蓄冷材料的凝固点、融点、融解热和相变过程中的热稳定性等热学性能。在热分析中 ,用示差扫描量热仪 (DSC)来测定蓄冷材料的融解热 ,温度传感器用来测定蓄冷材料的凝固点和融解点。通过热分析寻找到了一种新型蓄冷材料 ,其测试结果表明
The thermal properties include freezing point, melting point,the heat of fusion and thermal stability during the phase change process are investigated. In the analysis, the Differential Scanning Calorimenter(DSC) was used to determine the heat of fusion of the cool storage materials. The temperature sensor was used to determine the freezing point and melting point of the cool storage materials. The new cool storage material was found by thermal analysis. The results show that the cool storage material can be considered as an efficient cool storage material for cool storage air conditioning system.
