Description

Circulation breathing type double-layer curtain wall in a kind of

Technical field

The invention belongs to building field, be specifically related to a kind of interior circulation breathing type double-layer curtain wall.

Background technology

In cold district, for increasing the heat-insulating property of building, long ago just bring into use double window.After with the development of the universal curtain wall technology of glass and iron and steel technology, the concept of double window is incorporated among Curtain Wall, be double-layer curtain wall.The generation of phase at end of the seventies in last century oil crisis, people start building energy consumption to start to pay attention to.Meanwhile, the development of environmental protection consciousness, makes double-layered glass facade will obtain larger development in the near future.

At present, software and hardware fast development, makes the high complexity analog computation that designs double-layer curtain wall have large progress, and New Intelligent Control System also starts to introduce in double-layer curtain wall building.These are progressive also promotes double-layer curtain wall and progressively develops into the organic moiety of building integral, and active responding is made in the variation of weather to external world.

And air-conditioning extensive use is people when bringing a home from home, also band is served problem: indoor air quality (IAQ) worsens, and causes Cure of Sick Building Syndrome (SBA) to occur; A large amount of air-conditioning aggravation urban heat land effects, causes outdoor air thermal environment to worsen.The trend of the times of the proposition of the strategy of sustainable development and developing ecology building, just requires rationally to utilize natural wind energy to replace or part replaces traditional refrigeration air-conditioner, reduces and consumes non-renewable energy resources.And because natural wind energy provides fresh, clean air, improve indoor air quality, be conducive to the healthy of people, meet that people get close to psychologically, the demand of back to nature.

On the other hand, the aesthetic values that double-layered glass facade produces due to its transparency, also more and more for architect's emphasis is considered.

Existing double-layer curtain wall exists without changing wind system setting, and ventilation effect is undesirable, the shortcoming that degree with fresh air is poor.

Summary of the invention

In order to eliminate the above-mentioned shortcoming of traditional double-layer curtain wall, realize that sunshade is effective, ventilation effect good, the invention provides a kind of in circulation breathing type double-layer curtain wall.

Technical scheme of the present invention is:

Circulation breathing type double-layer curtain wall in a kind of, formed by outer curtain wall, internal layer curtain wall, solar protection devices and ventilation installation, between internal layer curtain wall, outer curtain wall, sealing forms hollow cavity, between internal layer curtain wall, outer curtain wall, form hollow cavity and be provided with air intake and air outlet, solar protection devices and ventilation installation are set in hollow cavity.

The present invention realizes energy-saving and environmental protection, sound insulation, and the comfort level of indoor life, working environment is improved greatly, and indoor environment gives the sensation of " it's like spring all the year round ".

The present invention, except possessing the repertoire of conventional curtain wall, has more outstanding feature in the following areas:

1, the screen window in ventilation installation can keep off mosquito and sand dust outside, allows ozone enter indoor.And by air hot pressing function, outdoor indoor dirty Bas Discharged.Improve the comfortableness of people's lives and accomplished clean environment firendly function.

2, anti-condensation: building dewfall is very harmful, dew is easily assembled dust condensing of building inner surface, damages inside plant, increases cleaning frequency, thereby affects the use of building, and produce extra cost.

The reason of dewfall and ambient humidity and internal-external temperature difference size are closely related, in the time that the temperature difference makes object internal surface temperature lower than dewpoint temperature, just can produce dewfall at object inner surface.For double-layer curtain wall, due to the effect of cavity buffer area, the temperature difference of the inside and outside both sides of internal layer cladding glass is reduced, internal surface temperature improves greatly.Concerning outer curtain wall, in cavity buffer area, temperature is higher, and the wet gas in buffer area is at any time by outside ventilation installation discharge chamber, so outer curtain wall inner surface can dewfall yet.This structure can increase substantially building and the life-span of decorating and the function of curtain wall, has also improved the permeability of curtain wall simultaneously.

3, natural ventilation: be positioned at the opening door-leaf that every layer of Curtain Wall arranges, meet the needs of safety smoke evacuation, and reach the function of the communicable disease such as natural ventilation, prevention SARS.

4, after automatically controlled abat vent is all packed up, be placed in the concealed blinds box of curtain wall top rail, as do not blocked, give brevity and lucidity, penetrating sensation, inside and outside not affecting, look effect.As long as flicking switch, abat vent just can put down at an arbitrary position, regulates the brightness of indoor light, light is evenly entered indoor, and the variation of the light that indulges in luxuriousness to one's heart's desire, improves Interior Illumination Environment.

5, noise-proofing: quantity research shows greatly, and thickness of glass often doubles, and corresponding sound insulation factor approximately increases 4dB.The present invention has improved the sound insulation property of curtain wall, and sound insulation property is than the high 20%-40% of conventional curtain wall.

6, Winter protection: enter winter, close the gas outlet of breathing curtain wall, make formation greenhouse, buffer area.Shine upon daytime and make warm room air accumulation of heat, temperature raises, and the outer plate glass temperature of internal layer curtain wall is raise, thereby reduces the inside and outside temperature difference of internal layer curtain wall.Effectively stop indoor heat outwards to spread.Night, outside temperature reduced, and by accumulation of heat air in buffer area, to outer curtain wall heat compensation, and Indoor Thermal measures corresponding maintenance, thereby no matter daytime and night, all can realize heat insulation function.

7, summer is heat insulation: enter summer, open gas outlet, utilize Air Flow hot pressing principle and stack effect, make the air that double-layer curtain wall is sucked by air inlet port enter buffer area, in buffer area, gas is heated, produce warm-up movement from bottom to top, by gas outlet, the hot gas in double-layer curtain wall is discharged to outside, thereby reduce internal layer curtain wall temperature, simultaneously, electric sunshading device uses, and effectively reduces outdoor solar irradiation and enters building interior, reduces indoor heat gain.So double-layer curtain wall has good heat-proof quality.

8, solar protection devices can be in summer, pass through to adjust abat vent according to the incident angle of sunlight, most sunshine is reflected back, make inner glass interface obtain solar radiant heat and all reductions greatly of air transmitted heat, not only stop part solar radiant heat to enter indoor, but also can adjust indoor light power.

In the winter time, abat vent is received in blinds box, can be received in a large number solar irradiation heat, reduce heating cost.

9, fast, the short construction period of on-the-spot installation rate, easy to maintenance.
