| 摘 要： | 建立了地板辐射采暖传热模型,分析了影响采暖盘管的散热因素。研究结果表明,管径增大导致地板表面温度增加趋势减小,管间距、热水温度增大导致供热区域地板表面温度分布呈周期性变化逐渐明显,且管间距变大导致其周期增加、热水温度变大导致其振幅增加,选择合适的地板层材料才能保证舒适的地面温度。

| Abstract: | A modified calculation model of heat transfer of floor heating system was proposed,analyzed the influence of the interior or exterior wall and the floor slab.The affecting factors of heat transfer of floor heating system were studied by using the new model.The results show that,the temperature growth of floor surface decrease,with increasing the diameter of pipeline.The temperature periodicity distribution of floor surface more clearly,with increasing the distance between pipelines or hot water temperature.... |
