Abstract

Abstract:

At present, there are few researches on the thermal storage performance of KAl(SO₄)₂·12H₂O and few thermal storage devices use KAl(SO₄)₂·12H₂O as phase change heat storage material. The preparation and thermal storage performance of KAl(SO₄)₂·12H₂O were summarized and the thermodynamic performance was analyzed. The thermodynamic performance analysis showed that the ambient temperature and initial temperature had little influence on the exergy efficiency of PCM, while the termination temperature had greater influence on the exergy efficiency. When the initial temperature is 328K and the ambient temperature is 288K, the optimal termination temperature is 370K. At the same time, KAl(SO₄)₂·12H₂O was applied to the mobile heat storage device by numerical simulation, and the change curves of liquid phase ratio and temperature with time were obtained. It shows that KAl(SO₄)₂·12H₂O is a kind of low temperature heat storage material with good performance.

Key words: exergy, thermodynamics, numerical simulation, phase change, potassium alum

摘要：

基于当前对KAl(SO₄)₂·12H₂O蓄热性能研究较少且很少有蓄热装置应用KAl(SO₄)₂·12H₂O作为相变蓄热材料的问题。对KAl(SO₄)₂·12H₂O的制备和蓄热性能进行了总结以及热力学性能分析，得出环境温度及初始温度对相变材料?效率影响较小，终止温度对?效率影响较大；当初始温度为328K，环境温度288K时，最佳终止温度为370K。同时，针对KAl(SO₄)₂·12H₂O应用于移动蓄热装置进行数值模拟，得到液相率、温度随时间的变化曲线。本文研究表明KAl(SO₄)₂·12H₂O是一种性能良好的低温蓄热材料。
