本文根据我国建筑结构的特点,从传热的角度考虑,将墙体结构按重量分成重、中、轻三类,用墙体非稳态传热理论和计算机模拟计算,对方程B(s)=0的根i对反应系数的影响以及反应系数项数对传热计算的影响进行了分析,提出了在不同墙型条件下,传热反应系数项数的确定值,进一步完善了传热反应系数法。
According to the characteristics of heat transfer, the wall bodystrucute in China can be divided into three types：heavy, medium andlight. Using the theory on unsteady heat transfer, a computer simulationis performed. The effect of the roots i of equation B(s)=0on the reaction coefficients and the effect of the number of terms in thereaction coefficient expression on the heat transer calculation are analyzed.The number of the terms in the reaction coefficients for different walltypes are determined, that is, n=96 for heave wall, n=72 for mediumwall and n=48 for light wall. Therefore, the method of heat transfer reactioncoefficient is improved.
