Detailed description of the invention
The external wall of high-rise building system of green low-energy consumption of the present invention as Figure 1-Figure 2, it mainly comprises the double-layered glass facade 1 be located at outside highrise building, be located at multiple photovoltaic solar cell plates 2 between double-layered glass facade 1, solar radiant energy can be locked between two blocks of glass by the technology of this double-layer glass, the insulating layer that formation is similar to " vacuum flask ", thus it is heat insulation to reach summer, the effect of Winter protection and sound insulation; Glass outer curtain wall adopts the ultra-clear glasses without the need to plated film, and when direct sunlight is irradiated on glass surface, glass can not produce dazzle because of mirror-reflection, no longer includes light pollution; Again can be not uneven because of glass internal/external heating yet, and there is curtain wall self-destruction phenomenon.The interior olo of double-layered glass facade 1 of the present invention expands 2000 ~ 5000mm to by 450 original ~ 800mm, and between two-layer glass, increase the multiple photovoltaic solar cell plates 2 being arranged on and adjustable shelf also can changing inclination angle with sun altitude change, thus reach the effect simultaneously utilizing solar electrical energy generation efficiently, and block solar radiation too much to a certain extent and enter indoor.
In addition, the radial section of building is rounded, and the radial section of double-layered glass facade 1 is the circle (certainly also can be designed to square, as Fig. 2) matched with the radial section of highrise building, make each time on building daytime can obtain evenly like this, maximum light-receiving area; Because the sun altitude of each area each time of every day is known, therefore like this by certain programming just can allow computer reach each block photovoltaic solar cell plate 2 of Based Intelligent Control facing to effect, just all vertically with sunray under different time can reach maximum generation efficiency with this photovoltaic solar cell plate 2.In addition, also light sensor 3 can be set on roof, will pack up when overcast and rainy and set level photovoltaic solar cell plate 2, make indoor reach maximum lighting quantity.The motor pattern of photovoltaic solar cell plate 2 will be divided into x, and y sways in direction.

Further, at air outlet 6 top, wind turbine 9 is also housed, air-flow is huge lifting power because stack effect is formed, and can promote turbo blade and rotate, export electric energy storage; And continuously overcast and rainy cause ascending air not enough time, the electric energy of deposit also can to wind turbine 9 input electric power, air draft of initiatively bleeding, and guarantee building room air is fresh.
In addition, helical structure slows down by ascending air, the glass that coefficient of thermal conductivity is lower is adopted in southern wall inner glass, and inside north wall, adopt the glass that coefficient of thermal conductivity is higher, so just can utilize around thermal current, regulate the uneven of north and south, building wall temperature, make interior temperature be tending towards even, reduce unnecessary air conditioner energy source.
Finally, also can in a bottom design pond 10 in double-layered glass facade 1 southern side of building, be connected with the greening water system outside building, can therefrom draw water, and atomization mechanism 11 is set at bottom air inlet place, by spraying high-pressure water mist, the air of coiling in the emerging wind passage 5 of spirality is made to not only reduce impurity content, and increase with humidity, air ratio thermal capacitance increases, more effectively cool photovoltaic solar cell, ensure its normal operation and maximum generation efficiency, and reduce potential disaster hidden-trouble.
In sum, exterior wall design of the present invention is conceived to the huge skyscraper of current energy consumption, proposes a series of energy saving optimizing and green transformation to its glass curtain wall structure.Main innovation devises: based on the spiral naturally emerging wind external wall structure of double-layered glass facade 1 technology, the pressure gradient-force that the air-flow risen by being heated by solar radiation produces, extract out indoor, building wait ventilate, and utilize air-flow naturally to have adjusted the temperature difference of building north and south wall at the around the movement of helical structure; In external wall structure, photovoltaic solar electrical plate intelligent regulates, can adaptively according to sun altitude in three dimensions, regulate photovoltaic solar electroplax towards, efficiently capture solar radiant energy, thus achieve the object of efficiency utilization solar radiant energy in city, significantly reduce the emerging wind energy consumption of highrise building, sketch the contours of the ecocity blueprint of sustainable development.
