The traditional heating wall is still beneficial to most rural residents for keeping warm in China, which has been used for thousand years.In the old method, the outstanding issue of the traditional heating wall is that the temperature of the room is dropped sharply at intermittent heating time, which can be solved by thermal storage heating wall with inner PCM.The temperature field, HFLUX, thermal boundary conditions and internal energy of the PCM would be changed over time during the process of heat transfer through the phase change process.Based on the principle of energy conservation, the temperature distribution of two formal heating walls will be calculated and analyzed The time of keeping an ideal indoor TEMP could be confirmed through figuring out the heat absorbed and given out during the process of phase change, the indoor temperature fluctuation is also analyzed during this time.The mutative temperature filed of the two types in the wall thickness direction will be confirmed by using the finite element numerical simulation method.Conclusion: the heating wall with inner PCM can release heat in the intermittent heating moment and reach the goal of time-delay and energy-saving, the indoor temperature can be reduced too.The new kind of heating wall has a great significance.
