ABSTRACT This paper reports the results of a study to investigate and develop correlations for the parameters affecting the time for complete solidification and fusion in spherical shells. For this study, four spherical shells of 35, 76, 106 and 131 mm diameter were used, the charging temperature was varied from −20°C to −5°C while the melting temperature varied from 10°C to 25°C. Water and mixtures of water and polyethylene glycol in percentages ranging from 7.5% to 50% were tested. The developed correlation for the time for complete solidification showed an agreement with experiments with maximum difference of about 5.91%. Validation of the correlation of the time for complete fusion showed maximum difference of 7.2% and minimum difference of 0.88% when compared with experimental results.

球壳封装 PCM 凝固和融合时间的实验相关性

摘要 本文报告了一项研究的结果，该研究旨在调查影响球壳完全凝固和融合时间的参数的相关性。在这项研究中，使用了直径为 35、76、106 和 131 毫米的四个球壳，装料温度从 -20°C 变化到 -5°C，而熔化温度从 10°C 变化到 25°C。测试了水以及水和聚乙二醇的混合物，其百分比范围为 7.5% 至 50%。完全凝固时间的发展相关性与实验一致，最大差异约为 5.91%。与实验结果相比，完全融合时间相关性的验证显示最大差异为 7.2%，最小差异为 0.88%。
