Abstract:
At present，the common single shape-stabilized phase change material ( SSPCM) can only work in summer or winter when used in internal or external surface on external wall． In order to improve the indoor thermal environment as well as reduce building energy consumption for the whole year and reduce the areas of refitting wall，this project proposes a new type of double SSPCM wallboard． The specific method is fixing SSPCM plates both on internal and external surface of external wall，the external layer with a higher phase change temperature active in
hot seasons and the internal layer with a lower phase change temperature active in cold seasons． In this project，the SSPCM plate is used on south external wall，and the study mainly analyzes the effects of phase change material thickness as well as phase change temperature on building energy consumption and building indoor thermal environment． The phase change wallboard thickness and their corresponding phase change temperature are recommended considering energy saving and economic factors． It can provide technical supports for the application of this structure in building energy saving．
