Description
Technical field
The utility model relates to energy-saving field, particularly a kind of energy-conservation fresh breeze window.
Background technology
The window in many coaches, city rail or high ferro compartment all is totally enclosed, even sealing is also made by some building offices.The reason of window sealing is had nothing in common with each other, and damages for prevent that the passenger from stretching out head, hand outside the car in Vehicle Driving Cycle when high ferro, bus high speed traveling, guarantees safety, and long-distance driving can prevent the pilferage of windowing again, and the convenient management of driving a vehicle; Office tower is to prevent that junk and personnel's danger from manufacturing and designing.Because the sealing of compartment and office building window, for guaranteeing wherein aptly Working Life of personnel, powerful air-conditioning and ventilation equipment must be installed, these equipment prices are expensive, energy consumption is huge, especially the window of compartment and office building uses the individual layer simple glass, and heat insulation effect is bad, causes energy huge waste.
According to statistics, the energy consumption of going along with sb. to guard him of housing construction accounts for air conditioning energy consumption 65%-75%, and energy consumption through window accounts for about 40% of air conditioner energy consumption.Compare body of wall, window has higher thermal transmittance, and energy consumption is had larger impact.See through glass window in the solar radiation in summer and enter the room, increase the refrigeration air-conditioner energy consumption.Under the construction conditions that does not have the sunshade measure, the door and window energy consumption that solar radiation causes accounts for about 50% of building energy consumption.In winter, can't rationally save with energy because of traditional forms structure, essential door and window opens and closes in people's life in addition, causes energy to escape.In general, the energy consumption that the Effect of Residential Windows high heat transfer coefficient causes accounts for 45-50% of energy consumption through window, and solar radiation accounts for 30% to the impact of energy consumption, and all the other 20-25% are opened and closed and leaked by door and window and cause.
The curtain wall of some office premisess or bus window post radiation prevention film or directly use measures such as preventing spoke low-E glass.But these materials can be resisted the radiation of the sun in summer, keep the preference temperature in the house, reduce the power consumption of air conditioner.But the heat that has also stopped simultaneously the sun in winter can not take full advantage of the heat energy of the sun, so that air conditioner still consumes more electric power.So these energy-saving materials are not special ideal.For the house, compartment of sealing, what people more were concerned about is how to keep the air of inside fresh at present.The big bus with air conditioners of long-time sealing, air is muddy, the passenger is concerned about more and more whether air contaminated in the car, air is fresh again keeps temperature in the big bus again, ventilate with energy-conservation be that people are in the insoluble contradiction of this design field all the time.
Scientist finds that vanadium dioxide has a kind of effect of mystery: vanadium dioxide has conductor-isolator conversion characteristic, is a kind of thermochromic material, and it can be with variation of ambient temperature from main regulation infrared waves transmissivity, and it has two kinds of crystal phase structures at normal temperatures.The vanadium dioxide material is under relatively low temperature during as isolator, be rendered as the monoclinic crystal phase structure, can see through infrared light, when higher temperatures, be transformed into the conductor body, present the tetragonal crystal system structure, the infrared light that can hinder 2500K-3000K sees through, another kind of crystal phase structure is then opposite, can see through infrared light.Two kinds of crystal phase structures can be changed mutually with the change of temperature, and the phase transition temperature of pure vanadium dioxide is 68 ℃.The vanadium dioxide optical property has larger variation before and after the phase transformation, and is large to the infrared rays transmitance before the phase transformation during cold state; After the phase transformation during high temperature attitude infrared rays transmitance little.This material is hindering infrared light more than 68 ℃ in other words, seeing through infrared light below 68 ℃, utilize this characteristics, deposit vanadium dioxide film at the poly-third uncommon film matrix, can realize the automatic adjusting to interior temperatures such as automobile, building, spacecrafts, utilize solar energy is intelligent thereby reach.The temperature that human body suits automatically is people's service 25 ℃ of room temperatures in order to make it suitable, and its phase transition temperature must regulate and control to be reduced near room temperature, and people have found the method that reduces phase transition temperature now, doping high price conductor ion such as W
6+, Nb
5+And Mo
5+Can reduce phase transition temperature, wherein the tungsten doping is best for lowering efficiency of phase transition temperature, by controlling suitable doping ratio, VO
2The phase variation can drop to room temperature.According to silicate research institute research report: hypovanadic oxide powder, mix tungsten salt, can make the conductor semiconductor phase-change temperature of vanadium dioxide be reduced to 25 ℃ of room temperatures or lower by mixing tungsten.After the phase transformation, infrared rays almost all is absorbed; At visible region, transmitance changes with temperature hardly; And in the infrared light district, great changes will take place for its optical property, is lower than phase transition temperature, and infrared light can highly see through, and is higher than phase transition temperature, and material can intercept infrared light and see through.Therefore, vanadium dioxide is a kind of ideal material of intelligent temperature control.
Usually be applied to energy-conservation field, needing film or the coating of preparation vanadium dioxide.The thin film technology method generally has two classes, and a class is based on the method for vapor coating, and such as sputter, pulsed laser epitaxy, air pressure chemical vapour deposition (CVD) etc., sputter comprises magnetron sputtering, reactive sputtering, ion assisted sputtering etc., and target can be conductor vanadium, VO
2Perhaps other oxides of vanadium are according to the different sedimentary conditions of raw material such as the differences such as substrate temperature, atmosphere.The another kind of method that chemical solution is processed, the i.e. precursor solution of employing modulation vanadium, the then plated film of being based on.(spin-coating method or czochralski method) adds at last thermal crystalline and prepares VO
2Film.Chemical vapour deposition (CVD) (CVD) also is a kind of CVD method, but the selection of raw material has certain restriction.Recently, atmosphere CVD sedimentation prepares VO
2Research gazed at very much, main advantage is that raw material is easy to get cheaply, does not need vacuum plant, deposition velocity fast and be easy to combine with existing float glass process etc.Chemical solution method is owing to adopting the soluble salt solution of vanadium, and raw material is cheap, preparation technology parameter is less, can realize that large tracts of land is prepared from the preparation method into the industrialization first-selection, is the most common VO that arrives in report so far
2The thin film technology method.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
As shown in Figure 1, a kind of energy-conservation fresh breeze window of the present utility model, comprise the top window frame 20 and the following window frame 30 that are arranged on hollow between two bodies of wall 10, be equipped with outer outdoor outer glass 50 and the internal layer of leaning between top window frame 20 and the following window frame 30 by indoor interior glass 40, described outer glass 50 arranges vanadium dioxide film 60 towards an outdoor side, and described top window frame 20 is provided with valve 21 towards the exit 22 of an indoor side.Top window frame 20 is installed a valve 21, and cold especially when wintry weather, and room air can be closed when good.
In the utility model, the intermediate space 70 of 5mm-6mm is arranged between described outer glass 50 and the interior glass 40, described top window frame 20 is communicated with intermediate space 70 with the hollow hole of following window frame 30.Top window frame 20 also is to make hollow to be communicated with indoor, extraneous fresh air is by filtering via two glass intermediate space 70, slowly flow into indoor, when simultaneously extraneous fresh air flows in crack, slow unlikely disturbance interior temperature to interior temperature and when flowing within doors.
In an embodiment of the present utility model, described following window frame 30 has fly net 33 towards air intake place 32 arranged outside of an outdoor side, and described following window frame 30 is provided with air filtration pieces 31 towards 32 inboards, air intake place of an outdoor side.Air filting material and fly net post in the air intake place, can select the M2.5-M10 filter as required, guarantee the cleaning that enters air.
In an embodiment of the present utility model, described following window frame air intake place 32 is provided with and the outdoor gutter that is communicated with 34.Consider that rainwater infiltrates and the dewfall below is equipped with outfall.
As shown in Figures 2 and 3, during cold weather, ambient temperature is lower than 25 ℃ (this sheet vanadium dioxide film design phase transition temperature is 25 ℃), the vanadium dioxide that film is coated with is rendered as the monoclinic crystal phase structure, can see through solar infrared light and heat radiation, give indoor heating, save the air conditioner electricity consumption.Bad such as room air, can open adjustable valve, allow outdoor air slowly flow into via space between window, come the preheating outside air by inwall glass simultaneously, make the cold air heating that enters, be unlikely to the disturbance interior temperature.Can close when the spy is cold winter.
During summer, ambient temperature is higher than 25 ℃, and the vanadium dioxide that film is coated with is transformed into metallic object, presents the tetragonal crystal system structure, and infrared light and the heat radiation that can hinder 2500K-3000K see through, and reduces the heat of the sun and invades, and saves equally the air conditioner electricity consumption.Bad such as room air, also can open adjustable valve, allow outdoor air slowly flow into via space between window, come the precooling outside air by inwall glass simultaneously, the hot gas that enters is turned cold, be unlikely to the disturbance interior temperature.When room air is good, can close.
The indoor-outdoor air exchange temperature runs off and the energy-saving heat preserving analysis:
For compartment or the office of sealing, what people more were concerned about is how to keep the air in the car (chamber) fresh.Especially for a long time be sitting in the big bus with air conditioners of sealing, perhaps be operated in the office premises of high-grade glass curtain wall closing, often stuffy, the easy cross staining of room air.So must take new venting practice, and the reinforcement of new wind venting practice certainly will be to cause temperature leak in the room, causes the waste of sky electro-mechanical force.If the method for the fresh air of introducing by pre-heating (or pre-cooled), make it leaked-in air temperature and indoor temperature near consistent, the house interior thermal perturbation will reduce, even ignores.The window that therefore should design adopts double-layer glass to install, and two glass sandwich air flow slowly to reach pre-heating (or pre-cooled).
Fresh breeze heat insulation experiment: the double window of supposing two kinds of forms of AB, be installed in respectively in two insulated buildings such as Fig. 4, two windows have the gravity vent of formed objects, but be different from: the A outside air directly enters indoor from window, the B outside air enters indoor from the window glass interlayer, and AB two window surface areas equate.Draught area Sa=Sb; Air velocity Va=Vb; Ta1 and Tb1 are the window internal surface temperature, and Ta2 and Tb2 are apart from air intake 5cmm place temperature nodes in the window.
During winter, when the Sa=Sb=0 ventilation opening is closed, Va=Vb=0, two window internal surface temperature Ta1=Tb1, Ta2 and Tb2 ignore, and temperature leak equates.When Sa and the unlatching of Sb ventilation opening, suppose air velocity Va=Vb, A window: Ta1 is equivalent to the ventilation opening closed condition, and the Ta2 temperature is equal to ambient temperature, the B window: because the glass sandwich Air Flow, interior window heat is exchanged, interior window surface temperature reduces Tb1＜Ta1, surface temperature loss B window＞A window, and the Tb2 temperature is preheated because of outside air
Tb2＜Ta2, the temperature leak B of place, air port window＜A window.From experiment, can find, when ventilation opening S opens, V size no matter, temperature T b2 all the time＞Ta2, intake air temperature loss B window forever＜the A window, data as shown in Figure 5 can fully be verified this point.Key is interior window surface temperature Ta1, Tb1 impact, illustrates whether the B window is less than A window temperature losses.
By test as can be known, Va is less to the temperature effect of Ta2, and the flow velocity of Vb is larger to the temperature effect of Tb1, and Fig. 5 is that actual measurement wind speed V is to the influence value (measuring condition state) of temperature in the foam room, two incubators are put within doors, and electric fan leaves incubator distance and fan gear speed control wind speed processed; The temperature inside the box is heated to 25 ℃ with hair dryer.Test period is December in winter, 5 ℃ of ambient temperatures).
Fig. 6 is A, and the comparison diagram of B window import wind speed and temperature is because B window Tb1 temperature is that gradient presents, therefore get up and down two ends average.Upper table data are made the Excel table relatively, can obviously see: V=0, Ta1+Ta2=Tb1+Tb2 is when wind speed hangs down, the rate of descent of Ta1+Ta2 is obviously greater than Tb1+Tb2, when V=0.2-0.6, difference is 14.2, and V=2.2, difference is 9.5, illustrate that wind speed improves, Ta1+Ta2 begins near Tb1+Tb2, and this trend is that the temperature leak that the B window is subject to when V increases will be the same with the A window.Usually V is less than 0.6, be enough for the renewal of room air, and the temperature loss of this moment is far smaller than the A window.To sum up, B window (interlayer unhurried current form) is satisfying under the prerequisite of ventilating, than A window (directly ventilation form) better heat preservation.
Same simulation summer temperature, the temperature loss of B window can draw same conclusions all the time less than the A window.
Intelligent power saving experiment: make two little insulated buildings with foamed plastics, a houselet posts the glass window (vanadium dioxide coating pastes the glass outside in the test) of vanadium dioxide coating, another cabin is equipped with ordinary glazed window, the K-type temp probe of difference insertion point Wen Yi in the middle of the cabin, the infrared Halogen lamp LED of installed in front (300w), the radiation of the imitation sun, put into from two houselet after-openings with ice bag, observed temperature meter reading, when environment temperature in the houselet during near 0 ℃ of point, take out ice bag, press lower manual time-keeping, light simultaneously Halogen lamp LED, temperature value such as Fig. 7 every 0.5 minute record two houselet: (environment temperature is 5 ℃, the phase transition temperature of vanadium dioxide film is 25～30 ℃), make temperature temporal evolution curve in the insulated building, such as Fig. 8; Shown by top two curves, in the time of 0 to 1.5 minute, namely 1 ℃ to approximately 25 ℃ the time, and two slope of a curves are the same, and programming rate is consistent, and houselet and the " VO of " common " group be described
