摘　　要：本文针对以哈尔滨为代表的寒冷地区的低温热水地板辐射供暖系统的传热特点和铺设方式 ,建立了构造层内传热过程的数学模型 ,分析了低温热水地板辐射供暖系统的热工性能 ,确定了构造层内温度分布、地板表面温度分布、单位面积散热量等设计指标与管间距、水温。In this paper,aimed at the heat transfer characteristics and the laying modes of the low temperature water radiant floor heating systems at Harbin,the heat transfer model of the floor heating is established,and the thermal performance of the radiant heating system is analyzed.The relationship of the designing parameters such as the temperature distribution in the floor,the temperature distribution and the heat flux on the floor surface and so on,with the pipe span,water temperature and the floor surface material are quantitatively obtained.
