摘 要: 以传热学理论为基础,建立了低温电地板辐射供暖非稳态过程的二维传热数学模型,并应用有限元分析软件ANSYS对数学模型进行了求解;通过实测及理论计算,得出地板内温度及热流密度分布特点;计算值与实测值相对误差小于10%。 Based on the theory of heat transfer, two-dimensional mathematical model of floor construction for the unsteady process of low-temperature electrical radiant floor heating system is established. The model is solved numerically with using FEM software ANSYS. Through the analysis of the results calculated from the model and testing, the computed distributions of temperature and heat flux in the floor of the heating system are obtained. The relative error of calculation from the tested results is less than 10 percent.
