Structural Optimization of Phase Change Energy Storage Heating Floor in Severe Cold Area

为分析相变储能供热地板翅片结构影响规律,改善其在严寒地区应用效果,通过ANSYS软件建立相变储能供热地板模型进行结构优化。模拟结果仅工况4、5的相变材料完全融化。相同金属用量下工况5较工况8相变材料融化速率更快、地面温度更高。在该建筑热需求下相变储能供热地板采用150mm间距2mm厚度翅片结构效果最优。结构优化中翅片间距改善效果大于翅片厚度。通过填充翅片结构的封装方式可提高相变储能供热地板在严寒地区的应用效果。

In order to analyze the influence rule of fin structure on phase change energy storage heating floor and improve its application effect in severe cold areas. The phase change energy storage heating floor model was established by ANSYS software to optimize the structure. The simulation results show that the phase change materials under conditions 4 and 5 were completely melted. Under the same metal mass, the melting rate of phase change material under condition 5 was faster than that under condition 8, and the ground temperature was higher. Under this thermal demand of building, the structure of phase change energy storage heating floor with 150 mm spacing and 2 mm thickness fins was the best effect. In the structural optimization, the improvement effect of fin spacing was greater than fin thickness. The application effect of phase change energy storage heating floor in severe cold area was improved by filling fin structure.
