摘要
利用有限差分法求解新型节能墙体砌块的三维温度场,将空气间层的热阻以导热、对流、辐射3种形式一一进行了计算,得到间层的热阻。进而采用电算法求出砌块的热阻,使得计算结果能精确地反映墙体砌块的热工性能。
By use of finite differential method, three dimensional temperature field of the new type energy saving building blocks is calculated. The thermal resistance is calculated one by one in the form of conduction, convection and radiation, then the thermal resistance of air layer is gained. Moreover, with simulation circuit method the thermal resistance of block is formulated, which can accurately state the thermal characteristics of building blocks.
