中文摘要	提出了一种采用定形相变材料蓄能的低温热水采暖地板形式。为了研究定形相变材料蓄能式低温热水采暖地板的传热性能,建立了该地板的传热分析模型。分析了相变材料的相变温度对地板表面平均热流密度和蓄能比的影响;比较了相变材料潜热蓄能地板与混凝土显热蓄能地板的热性能差异。结果表明:定形相变材料地板停止加热后仍可以在较长时间内保持稳定的热流密度。同时定形相变材料地板具有较大的蓄能比,使其夜间蓄存的热量可被更多地用于日间供热。; A structure of low temperature hydraulic floor heating modular board using shape-stabilized phase change materials (SSPCM) for thermal energy storage was illustrated in this paper. A theoretical model of analyzing thermal performance of such floor heating modular was developed. The effect of phase change temperature on the average heat flux and energy storage ratio of the floor heating modular board was analyzed by the simulation. The thermal performance difference between the SSPCM floor heating board and the concrete floor heating board was compared. The SSPCM floor can maintain stable heat flux for a long time without heating, which is difference with large fluctuation of heat flux of concrete floor. Also energy storage ratio of the SSPCM floor heating board is larger than that of concrete floor, which makes much more thermal energy be transferred and utilized for heating during day time.; 北京市“供热、供燃气、通风及空调工程”重点实验室资助项目(No．KF200413)
