覆盖物对低温热水地板辐射盘管散热影响分析

Influence Analysis of Covering Materials on Coil Heat Dissipation of Low-temperature Hot Water Floor Radiation

建立带有覆盖物的低温热水地板辐射盘管散热模型,利用F luent软件模拟不同覆盖物尺寸对低温热水地板辐射盘管散热的影响。研究结果表明:(1)在一定的覆盖物面积内,覆盖物面积增加造成地板局部升温。(2)在一定的覆盖物面积内,覆盖物的面积与地板的散热量减少成正比,但继续增加尺寸,其对低温热水地板辐射盘管散热的影响则不再明显。

The model of coil heat dissipation of low-temperature hot water floor radiation with the covering materials has been established,and the influences of coil heat dissipation of low-temperature hot water floor radiation at the different dimensions of covering materials were simulated.The results show that：（1） the increase of covering materials areas can cause the local floor temperature to rise at a certain extent of covering materials.（2） at a certain extent of the covering materials,the increase of covering materials areas is directly proportional to the decrease of the floor heat dissipation,but the influences of coil heat dissipation of low-temperature hot water floor radiation have not been obviously by increasing of covering materials areas.
