The effect of the different raw-material quality used at the beginning of run A was detected after 15h.
After about 55h,the process returned to its normal state mainly because the effect of the different raw-material quality was more evident throughout the microorganism growth phase (between 15 and 55h).

Keywords: PCMs phase change gypsum board, Heat transfer performance, Simulation analysis.
The simulation results showed that the heat transfer rate of composite PCMs(phase change materials) is higher than the PCMs, the mixture of diatomite improved the heat transfer performance of PCMs.
