针对一种自行开发的新型混合有机蓄冷工质，建立了描述凝固过程的数学模型，并应用边界元方法给出适用于凝固过程的解，最终得到了在不同Ｓｔｅ数时球内对称凝固的规律并在实验中得到了验证，为进一步优化这类蓄冷系统提供了理论依据。
A mathematical model describing the solidification process was established for a new hybrid organic regenerative refrigerant developed by ourselves. The solution to the solidification process was given by using the boundary element method. Finally, the law of symmetric solidification in the sphere at different Ste numbers was obtained. And in the experiment has been verified, in order to further optimize this type of storage system provides a theoretical basis.
