摘　　要：针对将相变材料(PCM)引入到轻质建筑墙板的结构中,可以有效地改善现有建筑墙板的高热阻和低热容的状况,采用焓法数学模型,对基本墙板、轻质墙板及重质墙板等含PCM材料的墙板热性能影响规律进行了系统地分析,研究了墙板中保温层与相变层材料的位置及其体积分数的动态变化对墙板热性能的影响.研究结果表明:足量的保温材料是墙板中PCM蓄能性能能够得到良好发挥的基本保障;PCM层处于保温层内侧时,墙板的热性能效果最佳;应尽可能将墙板中除保温材料和PCM以外的其他材料层设置在内侧,并且以轻质材料为佳.It is one of the effective ways to solve the problems of high thermal resistance and low thermal capacity by introducing phase change materials(PCMs)into lightweight wallboards for buildings.The enthalpy mathematical model was used to analyze the impact rules on the thermal performance of basic,lightweight and heavy wallboards outfitted with PCMs.The impacts of location and quantity variations of the insulation and PCM layers on the thermal performance of wallboards were investigated.The results show that adequate amount of insulation material in wallboards is the basic guarantee for the energy storage performance of PCMs.To obtain high thermal performance,PCM should be set inside insulation layer.The other material layers,except for the insulation and PCM layers,should be selected with lightweight materials and set as inner layers in wallboards for high thermal performance.
