摘要
通过改变混合物的成分配比可以有效地改变混合物物理特性，使其满足某一特定需求。实验研究了一种适用于蓄冷过程的有机混合相变材料，其相变温度范围为６—８℃，具有较好的凝固和熔化特性，没有出现通常的过冷现象。球内实验表明，Ｓｔｅ 数和球体直径是影响相变时间的两个重要因素。
Based on the physical properties of mixtures,this paper proposed an organic mixture for heat storage and the experimental investigation of the material phase change has been carried out.The results proved that the temperature of the phase change is about 6～8℃,the material has good melting and solidification characteristics and no subcooled happened during the phase change.The experiment also proved that the Ste and radius of the sphere has significant effect on the phase change time.
