摘　　要：由于相变材料的合理利用,能够有效提高建筑的室内热稳定性,降低建筑物的能源消耗;不同的相变墙体构造,其室内热稳定性也不同。为研究徐州冬季工况下适宜的相变墙体构造,通过ANSYS workbench软件,针对3种不同构造的相变墙体,模拟了其传热过程,并对室内外表面温度进行了分析。结果表明:徐州冬季工况时,内侧相变墙体内表面最低温度升高了0.35℃,相较于外侧和夹心相变墙体,提升幅度明显,同时,内侧相变墙体内表面温度的波幅也明显降低,内侧相变墙体对室内温度的调节作用明显,冬季工况下室内热稳定性最优。The rational use of phase change materials can effectively improve the indoor thermal stability of buildings and reduce the energy consumption of buildings.The interior stability of buildings with different phase change wall constructions is also different.In order to study the appropriate phase change wall construction for winter conditions in Xuzhou,in this paper,the heat transfer process of three different constructions of phase change walls was simulated by ANSYS workbench software,and the indoor and outdoor surface temperature were analyzed.It is shown that the minimum temperature of the inner surface of the inner phase change wall increases by 0.35℃during winter conditions in Xuzhou,which is a significant increase compared wity the outer and sandwich phase change walls.While the amplitude of the inner surface temperature of the inner phase change wall is also significantly lower,and the inner phase change wall has a significant effect on the regulation of the indoor temperature and the optimal indoor thermal stability during winter conditions.
