低温热水地面辐射供暖研究

摘要

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 ex-periment 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.
