摘要

相变储热技术是工程应用中高效储热的手段之一,而相变材料存在低热导率的问题,严重限制了其工作效率,因此需对相变储热装置结构进行优化以提高储热效率。选取五水硫代硫酸钠（Na₂S₂O₃·5H₂O）与三水合醋酸钠（CH₃COONa·3H₂O）作为相变材料,基于仿生结构设计6种相变储热模型,对两种相变材料在6种储热模型中的熔化和凝固过程进行数值模拟并分析,最后基于数值模拟结果,综合考虑储热与放热过程,搭建小型相变储热实验台。该文给出了在温度为75 ℃、流量为0.1 m³/h的工况下,两种模型在两种相变材料中各测温点温度随时间的变化。结果表明：一种储热模型更适合将Na₂S₂O₃·5H₂O作为相变材料,另一种模型更适合将CH₃COONa·3H₂O作为相变材料进行实际应用。

Abstract

Phase change heat storage technology is one of the efficient means of heat storage in engineering applications. However, phase change materials have the problem of low thermal conductivity, which seriously limits their work efficiency. Therefore, it is necessary to optimize the structure of phase change heat storage devices to improve heat storage efficiency. Na₂S₂O₃·5H₂O and CH₃COONa·3H₂O were selected as phase change materials. Six phase change heat storage models were designed based on bionic structure. The melting and solidification processes of the two phase change materials in the six heat storage models were simulated and analyzed. Finally, based on the numerical simulation results and taking into account the heat storage and release processes, a small biomimetic cross seasonal phase change heat storage experimental platform was built. This article presents temperature changes of two phase change materials at each temperature measuring point in two models under the operating conditions of 75 ℃ and 0.1 m³/h. The results indicate that one heat storage model is more suitable for using Na₂S₂O₃·5H₂O as phase change material, while the other model is more suitable for using CH₃COONa·3H₂O as phase change material.
