Abstract

The invention provides a heat-dissipation and energy-saving method for an external wall and a roofing of a building, which comprises the following steps: firstly, porous hydrophilic absorption materials are prepared; secondly, the porous hydrophilic absorption materials are arranged on floated coats or finishing coats of a wall body and the roofing, or inside structures of the wall body and the roofing; and thirdly, when the external wall and the roofing are influenced by external heat, moisture accumulated inside the porous hydrophilic absorption materials is evaporated slowly, so that the temperature of the wall body and the roofing is reduced. The heat-dissipation and energy-saving method for the external wall and the roofing of the building utilizes heat energy generated by solarization and sizzler to slowly evaporate the moisture which is absorbed by the porous hydrophilic absorption materials and dispersed inside the metope and the roofing, so as to bring away heat of the wall body and the roofing, avoid heat accumulation of the wall body and the roofing and improve the use function of the building, thereby achieving the aim of reducing the energy consumption of the building. The heat-dissipation and energy-saving method for the external wall and the roofing of the building is convenient to construct, adopts common and easily obtained materials, has low cost, and is suitable for energy conservation and emission reduction of buildings in areas which are warm in winter and hot in summer.

Description

technical field [0001] The invention belongs to the technical field of building engineering, and in particular relates to a natural heat dissipation and energy-saving method for building walls. Background technique [0002] In the prior art, the building walls are generally plastered with cement mortar, and the walls basically have no water storage function. In the southern region where the temperature is relatively high, with the prolongation of the sunshine time, the continuous increase of the outdoor temperature also makes the The temperature rise of the exterior wall of the building rises rapidly, which also rapidly increases the indoor temperature, thereby increasing the load of the air conditioner and wasting a lot of electric energy. At present, in order to reduce the energy consumption of buildings, people often install a circle or a layer of heat insulating material on the outer wall or inner wall and roof. However, using this method, the construction process is mor...
