Abstract：
According to the finite difference method calculates the temperature, heat transfer capacity and air conditioning cooling load in summer design condition for some energy-saving porous brick and hollow brick walls. Analyses the harmonic structure of internal temperature, heat transfer capacity and air conditioning cooling load of the walls by the Fourier series, and obtains the heat attenuation and phase delay.
