Description
Technical field
The utility model belongs to building energy conservation door and window fields, refers more particularly to a kind of vanadium dioxide intelligence sunshade hollow glass.
Background technology
The building energy consumption of China has accounted for 27.8% of social total energy consumption, and wherein the energy consumption of heating and air-conditioning accounts for 55% of building total energy consumption.In modern building, the area ratio that glass accounts for exterior wall is increasing, and the heat trnasfer undertaken by glass window according to measuring and calculating accounts for 48% and 7l% respectively at winter and summer.Regulate interior temperature according to air-conditioning, cryogenic temperature improves 2 DEG C, and cooling load reduces about 20%; Heat temperature and turn down 2 DEG C, heating load reduces about 30%, so be badly in need of the energy-efficient performance improving glass.
Vanadium dioxide material has first order phase change characteristic, can induced environment variations in temperature, this change of intelligent response realize to the band selective of sunshine through or cover.Usually, when environment temperature is lower than phase transition temperature, the film containing vanadium dioxide or coating are almost completely penetrating to the visible ray in sunshine and mid-infrared light; When temperature exceedes the semiconductor-metal phase change temperature of vanadium dioxide, vanadium dioxide undergoes phase transition and is converted into R phase, and now material to the selective blocking of mid-infrared light, can reach the object of transparent (visible light-transmissive) thermal resistance.Semiconductor-the metal phase change of vanadium dioxide is thermoinducible reversible change, and its temperature switch effect can be used to the ultrared break-make of centering and carries out Based Intelligent Control.Utilize vanadium dioxide under infrared light district high temperature low through with the high transmission under low temperature, the energy saving window port system of completely intelligence can be prepared.
Chinese Patent Application No. 200810033032.6 refer to a kind of intelligent heat-insulating film and preparation method thereof, Chinese Patent Application No.: CNl0l265374A discloses a kind of vanadium dioxide solar heat intelligent temperature control polymer film, they all prepare by directly being joined in thin polymer film by vanadium dioxide, significantly energy consumption can be reduced by sticking thermal isolation film or be coated with heat insulating coat on glass, there is transparency high, mist degree is less, can improve along with the rising of temperature ultrared rejection rate, play the function of intelligent sunshade.Its weak point is: the effective adjustment temperature due to this kind of temperature control of vanadium dioxide film is 35 DEG C-65 DEG C, general adhering film to glass can not reach said temperature change, also just can not this kind of for vanadium dioxide temperature control film optimum performance bring into play.
Application number is 201110397060.8, name is called that the patent based on the Bionic intelligent glass of temperature-sensitive hair-shaped nano hydrogel microsphere phase transformation is proposed a kind of temperature-sensitive sun protection glass, it can setting critical-temperature by transparent to opaque mutual conversion, can by critical-temperature 24 DEG C-40 DEG C settings by material mixture ratio.This kind of temperature-sensitive sun protection glass shaded effects are good, its weak point is: its off-color material is liquid or gluey, make to this temperature-sensitive sun protection glass and add difficulty, crucial shortcoming is, this temperature-sensitive sun protection glass is opaque when sunshade state, its scope of application that what this was serious limit.
Utility model content
The purpose of this utility model is to release a kind of vanadium dioxide intelligence sunshade hollow glass.It can give full play to the characteristic of vanadium dioxide, only plays sunshade effect when there is solar radiation in summer and glass transparent, shaded effects are good, keeps transparent when decumbent corydalis tuber illumination; All keep transparent in winter with or without illumination; And thermal transmittance is lower than 2.4W/KM2.The utility model has transparency high in sunshade and not sunshade state, the feature that mist degree is low, and shaded effects and good heat insulating.
For achieving the above object, the utility model adopts following technical scheme:
A kind of vanadium dioxide intelligence sunshade hollow glass, comprise at least two sheet glass, airtight cavity is formed by hollow glass adhesive tape or aluminium parting bead that molecular sieve is housed between two sheet glass, wherein a sheet glass is being provided with titanium dioxide vanadium layers facing in this one side of cavity, and the another side that it is characterized in that being provided with titanium dioxide vanadium layers glass is also arranged the airtight cavity that formed by hollow glass adhesive tape or aluminium parting bead that molecular sieve is housed with other one block of glass or be provided with low-radiation film in titanium dioxide vanadium layers.
Described titanium dioxide vanadium layers is vanadium dioxide coating.
Described titanium dioxide vanadium layers is the PVB or the EVA film that contain vanadium dioxide.
Described aluminium parting bead or hollow glass adhesive tape are provided with first band with the two sides that two panels glassy phase is combined, and two sheet glass surroundings are provided with second band.
Described low-radiation film is the saturating low-radiation film of height that light transmittance is not less than 70%.
Also a sheet glass is closely fixed with between described low-radiation film and titanium dioxide vanadium layers.
Described glass is ultra-clear glasses or sheet glass.
The utility model tool has the following advantages:
1, best energy-saving effect can be reached.
Energy-saving glass will possess two energy conservation characteristics: heat insulating ability and thermal insulation.Window energy-conservation on, the heat insulating ability (energy saving) of glass plays a major role.And will adapt with building location terrestrial solar radiation feature for the thermal insulation (shading coefficient S) of glass.China's hot-summer and cold-winter area has now been specified that will do external sunshade has reached building energy conservation requirement.The existing lower thermal transmittance of the utility model glass, having again intelligent external sunshade function, having lower shading coefficient when needing sunshade, is current optimal energy-saving glass.
2, intelligent shaded effects are remarkable.
So-called intelligent sunshade is exactly: intercept infrared rays when there is solar radiation in summer and play sunshade effect, do not intercept infrared rays in winter with or without solar radiation, can heating.
3, applied range is the developing direction of external sunshade industry.
The utility model is by termination product integrated with external sunshade system for door and window.Its installation does not affect outside vertical surface of building, easy cleaning, and solves current curtain wall and cannot install this difficult problem of external sunshade system.
Because the utility model glass is all transparent under any state, so be applicable to door and window and the curtain wall of various building, and the place such as train, automobile, steamer.Also may be used for the place that sun-proof and anti-evening glow is dizzy in addition.
