【摘要】：提出了一种预制轻薄相变复合供暖地板,将相变材料渗入硅钙板构造层形成相变蓄热层。并采用ANSYS数值模拟软件对该相变复合供暖地板的传热性能进行了数值模拟,给出了地面表面温度和热流及其向下热损失,并对相变复合供暖地板进行了经济性分析。研究结果为地面辐射供暖技术的推广和应用提供了理论依据。
[Abstract]:A kind of prefabricated light and thin phase change composite heating floor is proposed, which infiltrates the phase change material into the structure layer of calcium silicate plate to form a phase change heat storage layer. The heat transfer performance of the phase change composite heating floor is numerically simulated by ANSYS numerical simulation software. The surface temperature, heat flux and its downward heat loss are given, and the economic analysis of phase-change composite heating floor is carried out. The results provide a theoretical basis for the popularization and application of the floor radiant heating technology.
