中文摘要：

本文针对含多孔型地板的室内低温地板辐射采暖的传热问题进行研究，采用有限元法求解控制方程，分析了太阳辐射对整个室内空间温度场和速度场的影响，探讨了不同时刻太阳辐射对室内温度场和速度场的影响规律。在保证室内空气温度和速度均达到规范中冬季供暖的舒适性设计值的前提下，再根据温度和速度计算出PMV和PPD的数值，获得不同时刻下所需求的地板辐射热流密度最佳范围。

英文摘要：

The heat transfer problem for the indoor low temperature radiant floor heating which contains porous media is studied in this paper. The governing equations are solved by FEM. The impact of solar radiation to the entire interior space temperature and velocity fields are analyzed, the influence of indoor temperature and velocity field are discussed under the above conditions in different moments. On the premise of the indoor air temperature and velocity being up to the standard in winter heating comfort design value, then according to the temperature and velocity calculated from PMV and PPD, the demand for the optimum range of floor radiant heat flux is obtained at different moments.
