摘要

采用高清相机和红外热像技术，对组合相变材料融化-凝固循环过程与传热特性开展了可视化实验研究。以填充三种石蜡的相变蓄热腔体为研究对象，追踪了腔体内固液相界面的动态演化过程和温度分布的变化规律。在此基础上，考察了相变材料布置顺序对蓄热腔体热性能的影响，分析了组合相变材料蓄热腔体的相变行为及强化传热特性。结果表明，相变温度较高的相变材料应靠近加热壁面布置；组合相变材料蓄热腔体存在多个固液相界面现象，不同相变材料可同时融化/凝固；与单一相变材料相比，组合相变材料的应用改善了蓄热腔体各单元相变速率的均匀性，提高了平均相变速率；组合相变材料虽然降低了蓄热腔体的显热蓄热量，但减小了温度变化速率，增强了系统的稳定性，并显著增加了潜热蓄热量，有效提高了相变蓄热腔体的总蓄热量。

Abstract

Visualization experiments were carried out on the melting-solidification cycle process and heat transfer characteristics of the multiple phase change materials (multiple PCMs) using high-definition cameras and infrared thermal imaging technology. Three paraffins (RT65

RT42 and RT27) were used as multiple PCMs and filled into the TES container. The effect of PCM arrangement on thermal performance of the TES container was investigated. The dynamic evolution of solid-liquid interfaces was recorded by a high definition (HD) camera and the variation of temperature distribution was measured by an infrared camera. As the melting-solidification cyclic process was stabilized

the solid-liquid phase change behavior and thermal characteristics of the multiple-PCM TES container were obtained and compared with that of single-PCM TES container. The results show that the PCM with higher phase change temperature should be located near the heated wall. There exist multiple solid-liquid interfaces in multiple-PCM TES container

the paraffins in different PCM units can melt/solidify simultaneously. The uniformity of phase change rate is greatly improved by multiple PCMs

which increases the average phase change rate. The phase change fraction of multiple-PCM TES container is 40% higher than that of single-PCM TES container. Although the sensible heat storage capacity of multiple-PCM TES container is a little lower than that of single-PCM TES container

the variation rate of temperature is reduced

which enables the TES container work more stable. The latent heat storage capacity of TES container is significantly increased by the utilization of multiple PCMs. As a result

the total heat storage capacity of multiple-PCM TES container is 34.6% higher than that of single-PCM TES container.
