The glass curtain wall can play the roles of sun protection, heat insulation and better energy-saving effect than other coated glass curtain walls or doors and windows.
Description
The technical field is as follows: the invention belongs to the technical field of building energy conservation.
(II) background technology: nowadays, the use of large glass windows or glass curtain walls has become a fashion building. As is known to those who have learned physics, there are three ways and ways in which heat can be transferred: convection, conduction and radiation. According to the research of relevant aspects, 70 percent of building energy saving is in doors and windows, and 70 percent to 90 percent of door and window energy saving is in glass. Although glass curtain walls and doors and windows made of double-layer or triple-layer glass with good sealing performance and a hollow cavity structure with a heat-resistant medium layer (such as bridge-cut aluminum) can effectively block convection and conduction of heat, the heat is difficult to block radiation transmission through transparent glass in a heat radiation mode. Therefore, in summer, since sunlight and outdoor objects (outdoor buildings, trees, etc.) heated by the sun, even outdoor hot air, radiate heat into the room through the window glass in the form of heat radiation, the indoor temperature is rapidly increased. Although the cloth curtain can prevent the sun, the cloth curtain can not prevent the heat from flowing in, an air conditioner has to be used for cooling for a long time, and a large amount of electric energy is consumed for the cooling; in winter, the indoor temperature is higher than the outdoor temperature due to heating or heating by an air conditioner, and the indoor heat is greatly dissipated due to the heat radiation of the window glass, so that the heating load in winter is obviously increased, and the energy consumption is also increased. Some buildings adopt coated glass curtain walls or doors and windows which are complex in process and high in price, so that the heat radiation passing through the curtain walls and the window glass can be reduced to a certain extent, and a certain energy-saving effect is achieved. However, buildings using coated glass often have a more cloudy feel and are difficult to experience in bright sunshine. In addition, in order to achieve better lighting and maintain indoor brightness, the used coated glass has higher transmittance to sunlight, so that the heat radiation blocking effect is not very strong, and the requirements of sun protection, heat insulation and energy conservation can not be well met. In order to keep the sun from getting dry as much as possible, people usually install low-sagging white or other light-colored curtains in the glass windows or glass curtain walls even if coated glass is used. As mentioned above, the cloth curtain can prevent sunlight but cannot prevent heat from flowing in (summer) and out (winter), which causes air conditioning and heating losses. With the increasing number of glass curtain walls and large glass window buildings, the amount of electric energy consumed to cool using an air conditioner in summer and the amount of heating heat consumed to supplement heat by radiation heat dissipation through window glass in winter are increasing, and the total amount is quite remarkable. A class of technical products for applying reflective window films in glazings has emerged and rapidly developed in recent years. The method of sticking the reflecting film in the glass window is utilized to reduce the radiation transmission of heat, reduce the consumption of electric energy of the air conditioner in summer and reduce the energy consumption of heating in winter. This is in fact an inexpensive alternative to coated glass. The problem is that this solution also lacks flexibility like coated glass. Once the reflecting film is attached, the light transmittance and the light reflection rate cannot be changed, and the ratio of the penetration and the reflection of sunlight cannot be changed along with the change of spring, summer, autumn and winter, the change of morning, noon and evening hours, and the change of cloudy days: it is not expected to penetrate much when it is needed (e.g., winter, morning and evening, cloudy day), and it is not expected to reflect much when it is needed (e.g., summer, noon, especially long-term east or west sun exposure of east or west window in the morning or afternoon). Meanwhile, the ratio of reflection and transmission of the reflection film to sunlight is also fixed by 'a hammertoe': if a film with more reflection and less transmission is selected to be mounted, the indoor space is dark and not bright; if a film with less reflection and more transmission is chosen, the room is much brighter, but the effect of blocking sunlight and saving energy consumption of air conditioner (and heating) is much less.
The inventor has previously filed and obtained a patent of utility model, and confirmed the "transparent heat insulation energy-saving curtain" through "patent right evaluation report", because the reflecting film layer is not coated on the window glass (such as coated glass) or pasted on the window glass (such as window film), but is used as the curtain, which can be folded and put down according to the need, the above mentioned contradiction problem can be better solved: the transparent heat-insulation energy-saving curtain can reflect more (put down) when more sunlight is needed to be reflected, can transmit more (put up) when more sunlight is needed to be transmitted, is flexible to operate, has variable effects, and can be easily adjusted, controlled and converted according to needs, so that the requirements of sun protection, heat insulation, energy conservation and lighting can be met.
Common energy-saving doors and windows in the market at present mainly have three main types: heat-insulating aluminium alloy glass curtain walls and doors and windows (commonly known as bridge-cut-off aluminium curtain walls or doors and windows), plastic windows (commonly known as plastic steel windows) and aluminium-wood composite windows (commonly known as aluminium-clad wood windows). The curtain walls and the windows and doors are designed only for blocking heat from being transmitted through convection of air and blocking heat from being transmitted inside and outside in a conduction mode, but a large leak of heat transmission, namely heat radiation transmission through curtain walls and window glass, is ignored.
The Low-emissivity coated glass (namely Low-E glass) which appears and popularized in recent years has higher transmittance to visible light with the wavelength range of 380-780 nm, and is beneficial to indoor lighting; the reflective coating has higher reflectance for solar near-infrared radiation with the wavelength of 780-2500 nm and also has higher reflectance for middle-infrared and far-infrared radiation. Therefore, the low-emissivity glass can reflect infrared radiation from the sun and reduce the transmission of indoor and outdoor heat through the thermal radiation of the glass on the premise of ensuring higher visible light transmittance, and has excellent heat insulation and heat preservation performance. However, since the glass is complicated in manufacturing process, harsh in production conditions, and naturally expensive, it is impossible to use a coated product having a high reflectance to heat radiation.
The invention provides a sandwich glass curtain wall and a door window with a transparent sun-proof heat-insulating energy-saving rolling curtain, which is a technical scheme for combining a transparent heat-insulating energy-saving rolling curtain with a three-layer glass (double-cavity) sandwich glass curtain wall or a large glass door window. The technical scheme of the invention can be adopted for both heat-insulating aluminum alloy glass curtain walls or large glass doors and windows, plastic large glass doors and windows and aluminum-wood composite large glass doors and windows, so that the heat radiation problem of large glass penetrating through the curtain walls and windows is further solved on the basis of the original product capable of effectively blocking air convection and blocking heat conduction, and the sun-proof, heat-insulating and energy-saving effects are obviously improved. The technical scheme can be implemented when a new product is manufactured, and can also be used for carrying out technical transformation on the existing product used by a user. The glass curtain wall is suitable for being used on glass curtain walls or large glass windows of office buildings, glass door surfaces of shops, restaurants and the like, show windows, and large glass windows of balconies or villas of living rooms. The window sash combination is suitable for being divided into a plurality of small glass window sashes, particularly for windows with openable window sashes, and is also suitable for using transparent sun-proof heat-insulation energy-saving curtains.
In the prior art, a shutter roll blind is additionally arranged in a second cavity of a triple-layer glass (double-cavity) sandwich glass curtain wall or a large glass door window, but a conventional opaque shutter roll blind is additionally arranged, and the invention adds a plastic film or shutter roll blind with the capabilities of 'transparent sun-proof, heat insulation and energy saving' into the second cavity of the triple-layer glass (double-cavity) sandwich glass curtain wall or the large glass door window, so that the performance is much better.
(III) the invention content: the invention relates to a sandwich glass curtain wall and a door and window with a transparent sun-proof heat-insulation energy-saving rolling curtain, which has a specific structure similar to a triple-layer glass (double-cavity) hollow glass curtain wall and a door and window, and is installed by taking a bridge cut-off aluminum (or plastic) curtain wall and a large glass door and window frame with triple-layer glass (double-cavity) as a foundation: the frame, the outer layer glass, the heat insulation medium, the sealing strip, the middle glass and the outer layer cavity formed by the frame, the outer layer glass, the heat insulation medium, the sealing strip and the middle glass which are arranged outside the glass curtain wall or the large glass door window with sealing and heat insulation capabilities are kept unchanged, and the cavity of the inner layer of the door window is reformed; the inner part of the middle glass is kept with the frame, the heat insulation medium, the sealing strip and the inner layer cavity formed by the frame, the heat insulation medium, the sealing strip and the inner layer glass at the lower side and the two sides, but the middle glass, the inner layer glass and the upper part of the frame (the inner layer top frame) are not in the original fixed and sealed structure, but are movably sealed with a curtain box containing the roller shutter by using an aluminum alloy (or plastic) profile with a special structure. In addition, the section of the circular rolling curtain shaft hanging curtain in the curtain box is kept at the proper position of the opening on the inner layer cavity, so that a thin curtain body can conveniently enter the inner layer cavity, and the lower rod of the curtain with proper weight can ascend or descend in the inner layer cavity by controlling the forward and reverse rotation of the rolling curtain shaft according to requirements, so as to pack or unfold the curtain surface of the curtain. The term "removable seal" as used herein refers to a seal that is removable. The curtain box can be fixed on the upper end (top frame) of the inner layer frame of the aluminum alloy (or plastic) glass curtain wall or the large glass door and window through screws in a sealing way, and the curtain box can be simply and conveniently buckled on the upper end of the inner layer top frame of the glass curtain wall or the large glass door and window through special design and processing according to the specific structure of the glass curtain wall or the large glass door and window frame. The movable seal is required here, in order to form the effect of basic seal without air flow, and also to remove the curtain box as necessary to repair or replace the inner curtain surface and the control mechanism in the curtain box. In the curtain box, a manual zipper or an electric system for controlling the curtain to ascend and descend is arranged at a position outside the sealing cover. In addition, the curtain box is also provided with a mechanism which can limit the curtain surface from being rolled back excessively, or a curtain lower rod with proper width is used, so that the curtain lower rod can only move up and down in a specified interval and can not rotate reversely.
In order to conveniently place the curtain in the cavity of the glass interlayer and to operate and control the curtain, two methods can be adopted:
the method is to change the design of the top frame of the glass curtain wall or large glass door and window aluminum alloy (or plastic), to remove the aluminum alloy (or plastic) frame of the top frame of the glass curtain wall or large glass door and window frame, which originally seals the inner layer glass and the middle glass to form the inner layer cavity, and to replace the top frame of the part with a curtain box capable of matching with the top frame, so that the rolling curtain can smoothly enter the inner layer cavity from above, and like the conventional rolling curtain, the lifting of the lower rod of the curtain in the glass interlayer cavity can be controlled by using a manual or electric mode. The edge angle of the top edge of the inner layer glass is polished smoothly, so that the damage caused by scraping of the rolling screen surface which moves up and down can be avoided.
The other method is that the structure of the top frame of the existing aluminum alloy (or plastic) glass curtain wall or large glass door and window frame is not changed, but the height of the inner layer glass is selected (processed) to be a little shorter (a few centimeters), so that the top of the inner layer glass is not completely jacked to the head, a gap of a few centimeters is reserved, a detachable and sealable curtain box with a roller shutter therein is arranged at the gap, and the roller shutter in the curtain box can smoothly enter the cavity close to the inner layer and can smoothly go up and down. The method also needs to polish the edges and corners of the top end of the glass smoothly, so as to avoid possible damage to the rolling screen surface due to scraping.
The construction of the sandwich glass curtain wall and the door and window with the transparent sun-proof heat-insulating energy-saving roller shutter can be realized by only modifying a top frame at the upper end of an inner cavity and installing a curtain box internally provided with the roller shutter by keeping the basic structural design of a three-layer glass (double-cavity) structure glass curtain wall and a large glass door and window; the glass curtain wall and the large glass door and window with the structure of the existing two-layer glass and the single cavity can also be manufactured by adding a layer of glass, a cavity (namely, the double-layer glass is changed into the three-layer glass, and the single cavity is changed into the double cavity) and a sealing frame thereof, and enabling the upper end of the frame to be provided with a curtain box internally provided with a rolling curtain.
The roller shutter arranged in the inner cavity can be a plastic film roller shutter or a shutter type roller shutter. The plastic film rolling curtain is made of transparent plastic film which has the effects of transparency, sun protection, heat insulation and energy conservation and is plated with a metal mirror reflective film with strictly controlled thickness; the shutter type rolling curtain can be made of transparent hard plastic strips, and a metal mirror reflective film with strictly controlled thickness is plated on the outer surface of the shutter type rolling curtain, so that the shutter type rolling curtain has the effects of transparency, sun protection, heat insulation and energy conservation. The shutter type roller blind can also be made of opaque hard aluminum alloy strips or plastic strips, and the light transmittance is changed only by changing the angle of the shutter strips. The plastic film rolling curtain controls the total light transmission area by depending on the lifting curtain surface, and the shutter type rolling curtain controls the total light transmission area by depending on the adjustment of the angle and the gap size of the shutter strips besides the lifting curtain surface. The "total light transmission area" as used herein means an area where light rays not blocked by the screen are directly transmitted through the glass. The metal mirror reflective film with strictly controlled thickness means that the thickness of the metal film with the plated mirror surface is strictly controlled when a transparent plastic film used for a film type roller shutter is plated with a film or when a transparent hard plastic strip used for a shutter type roller shutter made of transparent hard plastic strips is plated with a film, so that the required light transmission and reflection ratio of each light wave band is obtained.
The film on the plastic film or plastic strip can be a single layer of direct film on a transparent plastic film or a hard plastic strip, or can be prepared by compounding the transparent plastic film which is coated with the required metal mirror reflective film with another layer of transparent plastic film or a transparent plastic hard sheet. For opaque louvered plastic or aluminum alloy strip material, the outward facing side is preferably also coated or compounded with a specular reflective film to more effectively reflect thermal radiation, but where the thickness of the coating is not strictly controlled since a transparency effect is not required.
The rolling curtain inside the curtain box has mechanical structure similar to that of conventional rolling curtain, and has movable sealing part, two ends with supports, cylindrical transverse shafts with proper diameter and connected to the supports, and the upper ends of the film or shutter of the curtain body embedded inside the slots in the transverse shafts for rolling up and lowering down. The lower part of the curtain body is provided with a flat curtain lower rod which can extend and fall down the curtain surface and is made of plastic or metal with proper weight. Outside the movable sealing part of the curtain box, a manual chain mechanism or an electric motor which can rotate a transverse shaft and is connected with the sealing part, and a control and transmission mechanism of the motor are arranged. For the shutter type curtain body, like the conventional shutter rolling curtain, the control mechanism not only can control the lifting of the shutter body, but also can control the shutter strips to rotate by different angles when the curtain body drops to the bottom so as to change the light transmission area.
In case of adopting film type rolling curtain in the glass interlayer cavity and the curtain box, the curtain body part is made of plastic film which is coated with a layer of mirror aluminum or other metal mirror reflective film on the surface by using a high transparent polyester film or a nylon film and the like as a base material through a vacuum coating or magnetron sputtering coating process, the light transmittance of the curtain body to visible light can be controlled between 3 percent and 70 percent according to the requirement, and the barrier rate to infrared rays can be controlled between 30 percent and 97 percent. Meanwhile, the mirror aluminum reflective film has high reflectivity (generally over 90 percent) to ultraviolet rays, is an additional benefit besides energy saving, and is beneficial to protecting human skin and furniture. Because the curtain can be flexibly operated and conveniently lifted according to needs to change the shielding area and the shielding state, the curtain can be usually made of materials with higher reflectivity (low transmissivity) to sunlight, and even can shield about 90 percent of infrared thermal radiation. Thus, the sandwich glass curtain wall and the door and window with the transparent sun-proof heat-insulating energy-saving roller shutter can obtain sun-proof energy-saving effects much higher than those of expensive coated glass, low-radiation coated glass curtain walls and large glass doors and windows with lower cost. The rolling curtain not only can show bright brightness of a pure glass window when being lifted, but also has unidirectional transparent capability to a certain extent even if the rolling curtain is completely put down, so that not only can people obviously feel the sun-proof and heat-insulating effect, but also people working indoors can see outdoor scenery clearly, and people are not confined in a dark room like a cloth curtain. For people using computers, the computer can also eliminate glare caused by sunlight and protect eyes of people. It goes without saying that for using glass curtain walls and large glass doors and windows, the sandwich glass curtain walls and doors and windows with the transparent sun-proof heat-insulation energy-saving roller shutter are adopted, so that the sun-proof heat-insulation energy-saving effect can be obviously improved, the roller shutter is higher in grade than a roller shutter, and the artificial damage can be avoided.
For the case of shutter type roller shutter in the glass interlayer cavity and the curtain box, the shutter body can be made of high transparent hard plastic strip material, and the outer surface of the shutter body is directly plated with a mirror surface aluminum or other metal mirror surface reflective film through vacuum coating or magnetron sputtering coating process, or the plastic film plated with the mirror surface aluminum or other metal mirror surface reflective film is compounded on the outer surface of the high transparent hard plastic strip material. The light transmittance of the material to visible light can be controlled between 3% and 70% according to requirements, and the blocking rate to infrared rays can be controlled between 30% and 97%; the blind body may also be made of opaque rigid plastic or aluminum alloy strip material. The outer surface of the glass can be polished or plated with a mirror reflection film so as to improve the reflection capability; or the outer surface of the plastic film can be compounded with a plastic film plated with a metal mirror reflection film to improve the reflectivity of the plastic film to heat radiation. In this case, the light transmission amount is controlled by completely depending on the lifting of the curtain body or changing the angle of the strips.
