相变材料蓄冷球蓄冷过程的研究
Study on heat transfer process in encapsulated phase change material balls
【摘要】 采用了焓法模型对一种新型的相变材料在球内的凝结过程进行了数值求解。得到了在第一类边界条件下相变时间与球径和传热温差的关系 ,以及相变界面位置变化与相变时间的关系等结果。该结论可以指导各种蓄冷器的设计和系统的蓄冷控制。
【Abstract】 The enthalpy model was used in calculating the solidification period of a new kind of phase change material in cool storage ball.The results such as the relationships between phase-change time and ball diameter,the relationships between phase-change time and heat transfer temperature differences,the relationships between phase-change time and the variation of phase-change boundary situation were obtained.These results could conduct the design of all type of cool storage container and control of cool storage system.
