| 摘 要： | 建立了分析空调贮能系统中管内流体流动管外PCM发生相变的相变的贮能器热性能的数学模型，并进行了数值计算。其中，把传热流体看作是沿轴向的—维无粘流动，对PCM相变过程的求解用显热容法。计算结果与文献中的计算结果吻合较好。所得结论对该类贮能系统的设计和性能优化有一定指导作用。

| Abstract: | Ttheoretical model and numerical study on the heat transfer process of a latent heat thermal storage module with flow fluid inside tube and phase change material(PCM) outside are presented for air-conditioning thermal storage system. The fluid flow is axial and the viscous heating is negligible. The temperature-based equivalent heat capacity method is used to analyze the solidification process of PCM. The agreement between the theoretical results and results in literature is satisfactory. A parametric study is also conducted. |
