摘　　要：应用计算流体力学软件分析确定火墙的内部构造形式。选择熔点较高,融解热较大的相变材料,将其封装、制成相变墙板应用于传统火墙壁面。通过计算和模拟分析得出,相变蓄热火墙是一种能有效吸收和利用火墙体内部烟气余热的采暖系统,这种创新式火墙具有较好的应用前景。The interior structure of the heating wall could be decided by the method of Computational Fluid Dynamics software. The selected PCM of both higher melting point and larger heat of fusion under continuous heating condition was sealed PCM and applied in the surface of the traditional heating wall. This new heating wall is effective for absorbing and using the heat of flue gas, and the indoor temperature will be kept within a stable range in the intermittent heating moment according to the Computer simulation methods. The heating wall with inner phase change materials has better prospect for application.
