建立尺寸为400 mm×400 mm×70 mm（长×宽×高）的模块化辐射供暖板的三维物理模型,采用Fluent软件研究供热水温度,供水流速及盘管间距对辐射板表面温度及内部温度分布、表面热流密度的影响。通过数值模拟得出结论,地板表面平均温度和热流密度随供热水温度的升高而升高,随管间距的增加而降低,供水流速对其影响较小。综合考虑供暖要求及经济性,最佳方案为:管间距为100 mm、供水流速为0.8 m/s、供水温度为28～30℃。

A three-dimensional physical model of a modular radiant heating board with a size of 400 mm×400 mm×70 mm(length×width×height)was established.The effects of heating water temperature,water supply velocity and coil spacing on the surface temperature,internal temperature distribution and surface heat flux density of the radiant panel were studied by using Fluent software.Through numerical simulation,it is concluded that the average floor surface temperature and heat flux increase with the increase of heating water temperature,and decrease with...
