低温热水地面辐射供暖研究

Research of Radiant Heating Floor with Low Temperature Hot Water

本文建立了地板采暖在空间内的传热模型,并且根据空气源热泵的特点,分析了在夏热冬冷地区采用空气源热泵作为分户式采暖热源时,运行费用的主要影响因素。通过数值模拟结果和实验测试结果的对比,确定了辐射地板热阻对于本采暖方式运行费用的影响程度;并提出改善辐射地板热阻才是解决夏热冬冷地区采暖问题的关键。

Aspacial heat- transfer model on floor heating is built in this article. According to the characteristics ofair- source heat pump,it showed the main reasons that influent the consumption while using air- source heat pump as pyrogenin household measurement area in this paper. The resultcomparison of numerical simulation and experiment explained how the thermal resistance of radiant floor works onthis kind of floor heating,and suggested that the key point to solve the heating problem in hot- summer cold- winter area is to improve the thermal resistance of radiant floor.
