摘　　要：随着供暖技术的发展、建筑物功能的逐步完善和人们生活质量的不断提高,选择一种经济、实用、环保、节能、可靠的采暖方式越来越受到人们重视。以新型采暖方式——低温热水地面辐射采暖为对象,建立了研究的几何模型及数学模型。通过具体的传热性能方面的计算和分析,从物体表面得热角度与传统散热器采暖方式对比,阐明了低温热水地面辐射采暖系统的优势。进一步揭示了低温热水地面辐射采暖室内温度比散热器采暖低2℃的理论根据,完善了低温地面辐射的理论研究,也为开发和改进新型采暖技术提供依据。With the development of heating technology and improvement of building function and people＇s living standard, an heating mode which is economic, practical, environmentcd and reliable is paid more attention to. A new heating mode-low temperature water radiant floor heating was investigated. Geometriccd and mathematic models were established. To anodize on heat transfer, the new heating mode was compared with traditional heating mode-radiator heating. Then advantages of this new heating mode were clarified. Furthermore, the theoretical basis on interior temperature 2℃ lower than radiator heating was opened out for this new heating mode. The theoretical research on low-ternperature radiant floor heating was perfected. And it can provide basis for exploiting and improving the new heating technology.
