摘　　要：分析了相变材料在建筑蓄能中的作用,对一种填充相变材料的建筑地面结构层蓄能过程进行了数值模拟研究,探讨了蓄能地面结构层内相变材料模块位置对结构层温度分布、蓄放热时间、供热工况以及相变材料利用率等因素的影响,得出在本模拟条件下满足所需功能蓄能采暖地板结构优化设计的方案.将模拟方案与实测结果进行对比后发现,两者的吻合程度较高.The action and function of phase change material（PCM） for building energy storage was studied. Numerical simulation of the energy storage process in building structure with PCM was conducted. The effects of PCM modules arrangement in building structure on temperature distribution, heating condition, energy storage and discharge time and PCM efficiency was investigated . The optimum PCM modules arrangement to satisfy the floor heating energy storage requirement is provided. Simulation program is compared with the measured results that shows good consistency.
