摘　　要：采用数值计算方法,计算出周期性非稳态边界条件下,用于建筑外墙的节能新型多孔砖砌体和空心砖砌体的温度及传热量,得到了准确详细的计算数据,在此基础上分析了砖体砌筑方式、孔洞形状、孔洞排列方式等对墙体传热的具体影响,给出了对比分析结果.By numerical method, the temperature distribution and heat flux of the new energy-saving wall with porous brick and hollow brick were calculated under periodic unsteady boundary conditions. Based on the detailed data, the influence factors on heat transfer of the wall were analyzed, such as the brick-masonry, holes shape and arrangement, and the results of comparative analysis has been given.
