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
The invention belongs to construction engineering technical field, be specifically related to the natural heat dissipation power-economizing method of construction wall.
Background technology
In the prior art, construction wall generally all adopts cement mortar to smear exterior wall, the essentially no water storage function of body of wall, more regional at temperature than higher south, along with the prolongation of duration of sunshine, the continuous rising of outside air temperature, the temperature rise of external wall is risen rapidly, thereby also fast lifting interior temperature, thereby air conditioner load is increased, waste a large amount of electric energy.At present in order to reduce the use energy consumption of building, people are many at exterior wall or interior wall and roofing, one circle or one deck heat-barrier material is set, and adopting this method, construction technology is comparatively complicated, wastes time and energy, and because heat-barrier material costliness, cause input bigger, in the area of warm summer heat of winters such as southern china, it neither best selection.
People know this general knowledge: can take away a large amount of heats on every side when water evaporates, thereby the environment temperature around making reduces.Around this principle,, can also take away the heat of body of wall ambient air simultaneously, reduce the environment temperature of periphery if the rising of body of wall temperature just can be slowed down or stop to evaporating from body of wall of can continuing of moisture.But, because present body of wall can not be accumulated moisture, make the body of wall suction adopt traditional way usually to the surface of wall watering, but be spread across the water meeting rapid evaporation on the surface of wall, thereby must frequently sprinkle water, the wasting manpower and material resources, and because the moisture that body of wall was absorbed in the short time of watering is very limited, cooling-down effect can not be lasting.
Summary of the invention
Technical problem to be solved by this invention is in order to solve the problem that existing external wall can not in time dispel the heat, to the invention provides a kind of lasting, natural heat dissipation and energy saving method that makes external wall and roofing.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
The heat dissipation and energy saving method of a kind of external wall and roofing, it may further comprise the steps:

3) outside exterior wall and roofing are subjected to during heat affecting, the moisture content of accumulating in the porous hydrophilic sorbing material i.e. slowly evaporation, constantly takes away the heat of exterior wall and roofing, reduces the temperature rise of body of wall and roofing.
Above-mentioned porous hydrophilic sorbing material can adsorb outside moisture in rainy or moist environment, and discharges the moisture of its storage when weather is hot, reaches the purpose of cooling energy-saving.
As to improvement of the technical scheme, it is further comprising the steps of:
11) in described step 2) body of wall that the porous hydrophilic sorbing material is set and roofing corresponding position interface is set;
12) can be in the interface setting to the water supply installation of the built-in porous hydrophilic sorbing material of exterior wall and roofing;
13) utilize this water supply installation to supply water, make it accumulate moisture content to described porous hydrophilic sorbing material.
Such scheme can in time keep the skin wet to the porous hydrophilic sorbing material, with the temperature of timely reduction external wall and roofing.
Described porous hydrophilic sorbing material may be selected to be with the set-up mode that body of wall or roofing combine:
1) the porous hydrophilic sorbing material is arranged in the floated coat of body of wall and roofing, or
2) the porous hydrophilic sorbing material is arranged in the seam of exterior trim surface layer of body of wall and roofing, or
3) the porous hydrophilic sorbing material is arranged in the concrete prefabricated decoration element of body of wall and roofing, or
4) the porous hydrophilic sorbing material is arranged in the brick body crack of body of wall and roofing.
As a kind of selection of technique scheme, described porous hydrophilic sorbing material is knitted and is weaved into rope form or one of netting shape or band shape, and it may be selected to be by polyethylene foam material or acrylic fibers and the cotton composite braided material that forms.
Another kind as technique scheme is selected, and described porous hydrophilic sorbing material also is a charcoal, and it is bar-shaped or fibrous that it is shaped as pipe.
Described porous hydrophilic sorbing material can also be the special sizing agent of energy gelling, and as cement-based mortar, lime putty etc., it can form loose structure after gelling.
Beneficial effect of the present invention is: the heat dissipation and energy saving method that the invention provides a kind of external wall and roofing, the heat energy that it utilizes Exposure to Sunlight and hot weather to produce, the moisture content that is dispersed in metope and the roofing through the absorption of porous hydrophilic sorbing material is slowly evaporated, and take away the heat of body of wall and roofing, avoid body of wall and roofing to form accumulation of heat, and improve the function of use of building, and then reach and reduce the purpose that building uses energy consumption.Its technological means is simple, convenient construction, and the material of employing is common to be easy to get, and cost is low, and this method is widely used in the building energy conservation that the warm summer in winter thermally distinguishes and reduces discharging construction, and can reach the natural energy-saving effect.
