| 摘 要： | 建立了组合式相变材料蓄热系统物理模型，在忽略显热的假设条件下研究了相变温度呈线性分布的组合式相变材料蓄热系统传热特性，得出了最优线性相变温度分布，并采用考虑显热的数值计算（有限差分法）证实了理论分析得出的最优相变温度与实际相变温度分布几乎相同。

| Abstract: | In this paper,a model of composite phase change material(PCM) for thermal energy storage system is built.The heat transfer charateristics in composite PCMs of linear phase change temperature(PCT) distribution is analyzed with the assumption of neglecting sensible heat and the optimum linear PCT distribution is obtained.Numerical calculation taking account into the sensible heat(infinite difference method) is adopted and the results prove that the optimum PCT distribution obtained from theoretical is in good agreement with the results of numerical simulation. |
