Building outer wall structure with double shaping phase change material layers
The invention discloses a building outer wall structure with double shaping phase change material layers. The building outer wall structure sequentially comprises the outer shaping phase change wall board layer, a first thermal insulation layer, a wall body layer, a second thermal insulation layer, the inner shaping phase change wall board layer from outside to inside, wherein the outer shaping phase change wall board layer and the inner shaping phase change wall board layer are respectively made of phase change materials of phase change temperatures of Tm1 and Tm2, the phase change temperature Tm1 is set to be minimum in cold load all year round in the expositing environment of the phase change temperature Tm1, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm1; the phase change temperature Tm2 is set to be minimum in heat load all year round in the exposing environment of the phase change temperature Tm2, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm2. The invention further designs the components and proportion of the phase change materials of the two shaping phase change wall board layers. By the building outer wall structure which is compact, high in adaptability, convenient to manufacture and maintain later, and the like, outer wall cold load and heat load can be lowered effectively, and overall energy consumption is lowered evidently.
