摘要

通过对管内流体换热和管外相变材料（PCM）发生相变的贮能换热系统模型的分析和求解，研究了贮能单元的尺度特性、Peclet数、Stefan数和PCM导热性能的影响，探讨优化系统效率的可行途径.对典型的以水为换热介质和以石蜡为PCM的贮能单元的研究结果表明，PCM内部的传热强化是提高贮能效率的关键因素.

Abstract

Based on the analysis and mathematical solution of a latent heat storage module with internal fluid flow

several factors

including the dimensional characteristics of the module

the Peclet number

the Stefan number and the thermal conductivity of the phase change material (PCM)

are investigated

and the ways to improve the systematic efficiency are also suggested.From the analysis of a typical module

in which water serves as the heat exchange medium and paraffin serves as the PCM respectively

the principal factor is to enhance the heat transfer inside the PCM.
