Abstract

Nowadays, large windows or glass curtain wall have become a kind of architectural vogue.Large area uses glass, while obtaining high light transmission effect, also because increasing the transmission intensity of heat radiation, and causes the increase of summer air-conditioning power consumption increased considerably and heat supply in winter is lost." transparent heat-insulated sun-proof energy-efficient roller shutter " like the hot shield and the reflective mirror that are erected inside windowpane, can effective blocking radiant heat, solve the power saving of windowpane.Its curtain part is to control between 3% to 19% using made of the transparent plastic film for being coated with mirror metal reflective membrane the transmissivity of visible light, and then control between 80% to 97% the rejection rate of heat radiation infrared ray.Using this curtain, light transmission capacity is easy to be adjusted and control as needed, has not only been able to satisfy the needs of daylighting, but also can reach energy-efficient purpose.

Description

Transparent heat-insulated sun-proof energy-efficient roller shutter

(1) technical field: the utility model belongs to energy-saving building technology field.

(2) background technique: nowadays, a kind of architectural vogue is had become using large windows or cladding glass.Although hollow The double pane or glass curtain wall of structure can reduce the convection current and conduction of heat, but difficult gear heat is led in a manner of heat radiation Cross the propagation of transparent glass.Therefore, to summer, outdoor objects (the outdoor architecture object, tree of heat are shone due to sunlight and by the sun Wood etc.), or even outdoor hot-air, heat can all be radiated into interior through glass by way of heat radiation.Although cloth Curtain can be sun-proof, but can't stop pouring in for heat, it has to be cooled down for a long time using air conditioner, and consumed thus Take a large amount of electric energy；And to winter, since room temperature is usually all higher than outdoor, but can because through glass heat radiation and Make indoor lost amount of heat, this will obviously increase the burden of heat supply in winter, equally increase energy consumption.Some buildings use valence The coated glass of lattice valuableness can reduce the heat radiation by glass pane to a certain extent, have certain energy-saving effect.But Using the building of coated glass usually to artificial at a kind of feeling that comparison is cloudy, it is difficult to experience the bright and beautiful of sunlight, and usually For preferably daylighting, manufactured coated glass to the barrier action of sunlight (ultraviolet light, visible light, infrared emanation) not It is very strong, sun-proof and energy-efficient needs cannot be met very well.In order to not shone as far as possible by the sun, even with coated glass, people Generally also the curtain of lowly vertical white or other light color can be installed in windowpane or glass curtain wall.It is as previously mentioned, this Although kind of a cloth curtain can be sun-proof, it can't stop pouring in for heat, air conditioner forced to work without cessation.As large windows are built Build it is more and more, annual summer be cooled down using air-conditioning and the electric energy more consumed and winter be supplement because of heat loss through radiation And the heating-amount more consumed, also all more and more, total amount is very surprising.Occur simultaneously fast-developing in glass in recent years A kind of technical products of patch reflection fenestrated membrane in glass window.The injection of sunlight is reduced using the method for reflectance coating is pasted in windowpane, Reduce the consumption of summer air-conditioning electric energy and the energy consumption of heat supply in winter.This is really a kind of cheap substitution shape of coated glass Formula.Problem is that this technical solution lacks flexibility also like coated glass like that.Once after sticking reflectance coating, light transmittance It cannot be changed with reflecting rate, sun cannot be changed as needed with the variation and the change in Morning Afternoon Evening division of day and night in season spring, summer, autumn and winter The ratio that light is penetrated and reflected: (such as winter, morning and evening) cannot penetrate more when needing to penetrate more, when needing to reflect strong (such as summer, in The east solarization or problem with a western exposure that noon, the especially window in the east or west encounter in the morning or afternoon) it is unable to multiple reflection.Meanwhile it reflecting Film itself is also that " giving the final word " has been fixed to the ratio of the reflection and transmission of sunlight: if selection installation is that reflection is more Few film is transmitted, that will make interior seem darkness without bright and beautiful；If selection installation is to reflect less and transmit more films, room It inside on the contrary becomes clear much, but block sunlight and the effect of saving air-conditioning (and heating) energy consumption are also much smaller.

The present inventor once applies for before this and obtains utility model patent, and passes through the " saturating of " Evaluation Report of Patent " confirmation Bright heat-insulating and energy-saving curtain ", due to not being (such as coated glass) by reflexed light film plated film on window-glass, nor being attached to window (such as window film) on the glass of family, but can according to need as curtain and pack up and put down, so that it may obtain the above problem To relatively good solution: " transparent heat-insulating energy-saving curtain " can either when needing multiple reflection sunlight multiple reflection (putting down), and can Transmiting (packing up) when needing more transmission sunlight, flexible operation, effect is variable more, it is easy to be adjusted as needed control and Conversion, so that can either meet energy-efficient needs, and can satisfy the needs of daylighting.But, " transparent heat-insulating energy-saving curtain " There is also some shortcomings and defect for technical solution, and currently proposed " transparent heat-insulated sun-proof energy-efficient roller shutter ", is exactly to " septum pellucidum The improvement and simplification of hot energy-saving curtain " technical solution, it is stronger to be allowed to practicability, is more convenient for popularizing.

(3) summary of the invention: the utility model " transparent heat-insulated sun-proof energy-efficient roller shutter ", specific mechanical structure and routine Roller shutter it is similar, have horizontal axis above, by the rotation that horizontal axis is forward and reverse, can curtain be rolled and be put down.Horizontal axis be by Made of metal or plastics.The bracket being mounted on wall at horizontal axis both ends is supported, horizontal axis rotation can be made by having on bracket Manually chain or electronic motor and transmission mechanism.Plastics or metal cross bar arranged at curtain lower part, and the weight of cross bar can be with Make slim and graceful curtain vertical stretching without waving." transparent heat-insulated sun-proof energy-efficient roller shutter " is different from conventional roller shutter and is characterized in, Curtain part is, by vacuum coating or magnetron sputtering membrane process, to be coated with one layer on its surface using high transparent polyester film The plastic film of mirror metal reflective membrane is made, and controls between 3% to 19% the light transmittance of visible light, to infrared ray Rejection rate then controls between 80% to 97%.Simultaneously as mirror metal reflective membrane also has very high reflectivity to ultraviolet light, This is the additional benefits except energy conservation.Such technical characteristic requirement, is different from original " transparent heat-insulating energy-saving curtain ". At original " transparent heat-insulating energy-saving curtain ", although also proposed, " its main part is using " being coated with to visible light and heat radiation The transparent plastic film of reflective metal film of the infrared and far infrared with part reflection and fractional transmission ability " is (usually poly- Ester film) made of, " and propose, except in the case of being used cooperatively with cloth curtain, itself can also have single-layer curtain Or the structure of two kinds of forms of Double-layer curtain.When using the double-deck curtain structure, the light transmittance of two layers of curtain can be controlled respectively 20% ~50% and 50~80%, it respectively corresponds compared with high reflection and compared with two kinds of situations of high transparency, to meet different periods to illumination not With needs；It is self-evident, be clearly using the double-deck curtain structure it is more complicated, install also pretty troublesome.In this regard, " septum pellucidum The sun-proof energy-efficient roller shutter of heat " technical solution is simplified, only with single layer curtain structure.Former " transparent heat-insulating energy-saving curtain " skill Art scheme is it will be seen that the transmissivity of light controls between 20%~70%, by curtain itself when using single layer curtain structure Light transmission ratio and the size of windowpane shielded area is controlled by the entrance of sunlight and heat radiation and sheds.And it is " transparent heat-insulated Sun-proof energy-efficient roller shutter " not only only uses single layer structure and does not have to many and diverse double-layer structure, and will be seen that the transmissivity control of light It makes between 3% to 19%, rather than between the 20%~70% of original scheme.At the same time, and directly it proposes to infrared Requirement of the rejection rate of line between 80% to 97%, this is all the technical characteristic different from original technical solution.Because former The transmissivity for carrying out the visible light of technical solution proposition controls between 20%~70%, just compares and is difficult to realize to infrared emanation High barriering rate, generally can only achieve 50%~75%.And the improved present invention, just highlight curtain can with flexible operating, The advantages of convenient for being changed state as needed, thus using the material system to sunlight with high reflectance (low transmission rate) Make.In this way, using just more convenient, effective and practical: when not shining upon, packing up curtain, can enjoy pure Windowpane high transparency light and it is bright and beautiful；And when shine upon need sunshade thermal insulation when, put down curtain, can be by 90% or so Heat radiation barrier outside, realize efficiently significantly energy saving.And at this moment, although curtain is lower to the transmissivity of visible light, But it is too many because can't actually be reduced to indoor brightness in the state bying sunlight, it can but make one to feel apparent Sun-proof, heat-insulated, energy-efficient effect still makes one to feel nice and cool, but also be avoided that using computer even if air conditioner underdrive operating When because sunlight generate glare, protect the eyes of people.But, since the transmissivity of visible light is lower, when watching outdoor scenes, It can seem vivid not as former scheme.

Another specific features of " transparent heat-insulated sun-proof energy-efficient roller shutter " are used as the reflective metal film that is coated with of curtain Plastic film material has two kinds of forms of single plastic layer structure and multi-layer compound structure, it can directly being coated with using single layer The transparent plastic film of reflective metal film makees curtain, or using the side for being coated with reflective metal film be also compounded with coloring layer and The composite construction film of rubberised layer and overlay protective layer makees curtain, overall thickness 0.01 millimeter to 0.20 millimeter it Between.

" transparent heat-insulated sun-proof energy-efficient roller shutter " can be mounted on cloth by the case where for being already installed with cloth curtain Outside curtain, it is energy-efficient to play the role of sunshade thermal insulation, also can put down cloth curtain when needing further shading.Family makes " transparent heat-insulated sun-proof energy-efficient roller shutter " is exactly used cooperatively by the used time with cloth curtain, not only can be with sunshade thermal insulation energy conservation, but also energy There is a beautifying and decorating effect of cloth curtain, when sleeping at night can be with shading.

Since used polyester film has enough intensity and toughness, for what is only wound and put down For roller shutter, due to not allowing to be also easy to produce mechanical damage, so that it may directly by the material of the membrane material strap of upper and lower ends etc It thickeies, and after ordering conjunction with stapler, is inserted directly on curtain in the empty slot of horizontal axis and sheer pole, and do not have to again plus cloth Side.

(4) Detailed description of the invention: due to " transparent heat-insulated sun-proof energy-efficient roller shutter " in mechanical structure with existing roller shutter basic one It causes, therefore attached drawing picture is to be different from common curtain " transparent heat-insulated sun-proof energy-efficient roller shutter " curtain structure section figure.And by It is almost the same with the section structure of original " transparent heat-insulating energy-saving curtain " in " transparent heat-insulated sun-proof energy-efficient roller shutter ", it is poor It is coating film thickness difference, and this difference is difficult to show on schematic diagram, therefore schematic diagram is the same.Attached drawing 1 is single Layer plastic film aluminium coated fabric.Attached drawing 2 is in the metal reflective film surface being coated with added with transparent protective coating or coloring layer Structure of composite membrane.Attached drawing 3 is the duplicature composite construction in the metal reflective film surface being coated with added with transparency protected plastic film layer. Double-layered compound film is laminated generally by adhesive, is also had using electrostatic attraction and is combined with each other.Label 1 indicates Bright plastic film substrate.Label 2 indicates the reflective metal film being coated on substrate.Label 3 indicates the transparent of metal reflective film surface Protective layer or colouring coating or compound layer of transparent plastic foil.Label 4 is indicated in metal reflective film surface (or metal reflective Film strips have the surface of coloring layer) compound layer of transparent plastic foil when transparent rubberised layer used.

(5) specific embodiment: as required install curtain window required for size, with it is with composite construction, Polyester plastics membrane material with reflective layer of aluminizing cuts out the curtain " curtain " of size required for being processed into.It aluminizes reflective layer Saturating visible light rate can choose 10% or so, and should select the rejection rate of heat radiation 90% or so.By top " curtain " While getting up to be thickeied with strap winding, and fixed with staple, the empty slot of horizontal axis on roller shutter is packed into as conventional roller shutter In frame.Curtain is rolled again, reserves the lower edge of " curtain ", equally lower edge also winding gets up to thicken with strap, be used in combination Staple is fixed, and is packed into the empty slot frame of roller shutter sheer pole like that also like conventional roller shutter.In this way, " transparent heat-insulated sun-proof a section The roller shutter of energy " is just made.It is then " saturating by what is made again as long as bracket is mounted to a wall according to preparatory measured size The bright energy-efficient roller shutter of heat insulation sun " is installed on bracket.
