Description

Smart liquid flow window and smart liquid flow window system of plasmon suspension mixing of colors

Technical Field

The invention relates to the technical field of building energy-saving building enclosures, in particular to a smart liquid flow window with plasmon suspension liquid color mixing and a smart liquid flow window system.

Technical Field

Buildings consume 40% of the energy worldwide, and carbon emissions from building construction are one of the fastest growing areas. The emission of greenhouse gases causes global warming, and a secondary station in countries around the world is at the turning point of energy revolution. The peak value is reached in 2030 years before Chinese striving, and carbon neutralization is realized in 2060 years before. Renewable energy sources such as solar energy are utilized in the building to replace traditional fossil fuels, so that the high-energy-consumption building can be converted into a zero-energy-consumption or near-zero-energy-consumption building (zero-energy or net-zero-energy building), even into an energy-production building (energy-plus building), and green and low-carbon conversion of the building is realized.

The liquid flow window is a novel energy-saving window body capable of absorbing and utilizing solar heat energy. Under the condition of not influencing the building attractiveness, the large-scale building external window area in the modern building is fully utilized, and an additional installation site is not needed. The heat energy converted from solar energy is utilized in the building, so that the energy consumption of a hot water system in the building is reduced; the heat gain of the room is reduced, so that the energy consumption of the air conditioning system in summer of the room is reduced; meanwhile, the heat returning to the outdoor environment is reduced, and the urban heat island effect is relieved. However, to date, the most widely used first fluid in the flow window is colorless, non-toxic distilled water, which has very low solar absorptivity, thus resulting in inefficient use of solar heat throughout the window. In addition, the user can only reduce excessive visible light entering the room by using an inner shading mode or an outer shading mode, so that indoor glare is reduced, indoor light comfort is improved, and the user cost is increased. Although the addition of dyes to the first fluid has been studied to increase solar absorption, it is well known that organic dyes fade in long-term sunlight, while inorganic dyes are mostly toxic and resistant to use by RoHS et al, and thus the smart window for dye matching has not been widespread to date.

The common method for adjusting the sunlight white light to produce colored light is to absorb part of the visible light by a molecule or a semiconductor material, or emit visible fluorescence after absorbing ultraviolet light. The common method has the defects that the molecules are changed into an excited state from a stable state after absorbing light, absorbed photon energy is concentrated in a plurality of atoms forming the excited state, the molecules have chemical decomposition risk, and the method is a scientific principle of dye fading. Unlike molecular absorption, semiconductor absorption, in which the energy of each absorbed photon is used to excite an electron from the valence band to the conduction band of the semiconductor, the valence and conduction bands of the semiconductor are composed of many atoms, and the risk of failure of semiconductor decomposition by sunlight is much lower than the risk of molecular decomposition by sunlight. However, chemical components of semiconductors, such as cadmium selenide and cadmium telluride, which are commonly used for absorbing sunlight to adjust visible colors at present have the defect that heavy metals pollute the environment. The invention discloses a method for adjusting color by chemical components, which is characterized in that when the size of a material is reduced to be below a few nanometers, the light absorption and fluorescence properties can be adjusted by the size of the material without depending on the traditional color adjustment by the chemical components of the material, particles with singular quantum physical properties and sizes less than a few nanometers are generally called quantum dots, and the graphite type carbon quantum dots are regarded as high-quality novel optical materials due to the chemical stability and the environmental friendliness of the graphite type carbon quantum dots, but the known graphite type carbon quantum dots have weak fluorescence intensity and are not enough to forward ultraviolet light to fluorescence in sunlight to adjust the color of the sunlight.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.

Example 1

According to fig. 1-7, a smart flow window for plasmon suspension toning, i.e. a smart flow window for toning with a plasmon suspension. The embodiment 1 provides the following exemplary technical solutions for the shortcomings and market demands of the prior art liquid flow window technology in building aesthetics and indoor light comfort.

According to fig. 2, the plasmon suspension toning smart flow window comprises afirst glass plate 201 and asecond glass plate 204 which are oppositely arranged, asealant 209 is arranged at the peripheral edge area between thefirst glass plate 201 and thesecond glass plate 204, and thefirst glass plate 201, thesecond glass plate 204 and thesealant 209 enclose a firstclosed cavity 205; thesealant 209 defines one or more openings for the passage of fluid into and out of the firstenclosed cavity 205. Preferably, the distance between the first glass plate and the second glass plate of the firstclosed cavity 205 is 5-100 mm.

According to fig. 3, afirst fluid 206 is arranged in the firstclosed cavity 205, thefirst fluid 206 comprising a plasmonic suspension capable of converting ultraviolet and violet light into visible fluorescence light of one or more wavelengths. Preferably, the plasmons absorb ultraviolet and violet light in sunlight and emit one or more fluorescence spectral peaks at wavelengths 400-700 nm.

The plasmon absorption light is another singular quantum physical phenomenon, and particularly refers to that in a solid with a certain carrier concentration, the carrier concentration at one position in a space is changed due to absorption light through coulomb interaction among carriers, and the carrier concentration at other positions near a few nanometers is induced to oscillate to emit light. Because the metal has extremely high carrier concentration, the embodiment uses extremely stable silicon dioxide/aluminum oxide to coat the nano silver to design and prepare the plasmon which absorbs ultraviolet light and purple light and emits visible fluorescence, and is matched with the graphite type carbon quantum dots which absorb the ultraviolet light and the purple light and emit the visible fluorescence, so that the synergistic fluorescence effect is generated to increase the fluorescence intensity, the ultraviolet light and the purple light can be sufficiently transferred to adjust the color of sunlight in the sunlight, and the chemical stability and the production cost are low.

Preferably, the suspension of the plasmon suspension adopted in the present embodiment 1 comprises nano silver plasmons with the size of 30-50nm, silica or alumina coated with the plasmons and with the thickness of 10-20nm, and graphite type nano carbon quantum dots with the size of 2-4 nm. It will be understood by those skilled in the art that preferably, the plasmon is nano silver, the graphite type nano carbon of 2-4nm is quantum dot, and the silica or alumina coated with nano silver and having a thickness of 10-20nm is an insulating spacer (insulating spacer), in other words, an insulating spacer for regulating the distance between the carbon quantum dot and the silver plasmon, and the suitable distance of the insulating spacer helps the carbon quantum dot and the silver plasmon to resonate, so as to achieve the fluorescence intensity of the plasmon enhanced quantum dot.

Preferably, those skilled in the art will appreciate that, by varying the composition or composition of the plasmonic suspension, the wavelength of the excited fluorescence can be varied and further the color and shade of the light transmitted through the flow window can be varied.

Preferably, the plasmonic suspension contains less than 0.01% cadmium, less than 0.1% each of lead, mercury, chromium, arsenic, tellurium, polybrominated biphenyls, and polybrominated diphenyl ethers.

Preferably, thefirst fluid 206 may also comprise an aqueous fluid, an antifreeze fluid, or a combination thereof.

Thefirst fluid 206, which has a temperature increased by solar radiation, flows upwards in the first sealedcavity 205 along the first glass plate with a higher temperature, reaches the side of the submerged heat exchanger in the first sealedcavity 205 to release heat, and flows downwards along the second glass plate with a lower temperature after being cooled, so that the whole body flows in a ring shape.

According to experiments, the plasmon suspension is found to be stable in performance. Accelerated aging tests have shown that the operating life of the plasmonic suspension exceeds one year in outdoor sunny days. This means that the plasmonic suspension only needs to be subjected to maintenance inspection once a year or two years, and the operation and maintenance costs are low.

Preferably, thesecond fluid 208 flows in a unidirectional manner within the submerged heat exchanger, absorbing heat from thefirst fluid 206 and flowing to the next smart flow window connected in series; or the heat collecting device flows to the building after reaching a certain temperature set by a user.

According to fig. 3-5, at least one submerged heat exchanger is arranged at thesealant 209, and the submerged heat exchanger comprises an inlet-side horizontal connectingpipe 301 and an outlet-side horizontal connectingpipe 305 which are arranged outside the firstclosed cavity 205, an inlet-side vertical connectingpipe 302 and an outlet-side vertical connectingpipe 304 which penetrate through thesealant 209, and a main body heat exchangehorizontal pipe 303 arranged in the firstclosed cavity 205; the outer ends of the inlet side vertical connectingpipe 302 and the outlet side vertical connectingpipe 304 are respectively communicated with the inlet side horizontal connectingpipe 301 and the outlet side horizontal connectingpipe 305, and the inner ends of the inlet side vertical connectingpipe 302 and the outlet side vertical connectingpipe 304 are respectively communicated with the two ends of the main body heat exchangehorizontal pipe 303; thesecond fluid 208 is provided inside the submerged heat exchanger, and the main body heat exchangehorizontal pipe 303 enables thefirst fluid 206 to exchange heat with thesecond fluid 208.

According to fig. 3, the fixed sash is U-shaped in cross-section for fixing thefirst glass plate 201 and thesecond glass plate 204; according to fig. 1, the fixed window frames include afirst window frame 101 positioned at an upper side, asecond window frame 102 positioned at a left side, athird window frame 103 positioned at a lower side, and afourth window frame 104 positioned at a right side. The fixed window frame can be vertically arranged or obliquely arranged according to the inclination angle of the curtain wall.

Preferably, thefirst glass plate 201 is installed toward the outdoor side; thesecond glass plate 204 is installed toward the indoor side. Thefirst glass plate 201 and thesecond glass plate 204 are fixed and sealed by asealant 209 to form a first sealedcavity 205 and prevent thefirst fluid 206 in the first sealedcavity 205 from leaking. The distance between the firstclosed cavities 205 can be controlled within the range of 10-30mm, and the highest comprehensive energy-saving rate of a hot water system and an air conditioning system of the liquid flow window is ensured. Preferably, thefirst glass plate 201 and/or thesecond glass plate 204 may be coated, such as low-e coating, to improve the energy saving performance of the window. Preferably, thefirst glass pane 201 and/or thesecond glass pane 204 may be a double insulating glass unit or a triple insulating glass unit to improve the thermal insulation of the window.

According to fig. 6, thefirst window frame 101 has 3 openings, including the end of thefirst opening 210 located at one side of thefirst window frame 101; thesecond opening 211 and thethird opening 212 are arranged side by side along the length direction of thefirst sash 101 and located at the end of the other side of thefirst sash 101. The first and second opening holes 210 and 211 are for the inlet side and outlet sidevertical connection pipes 302302 and 304, respectively, of the submerged heat exchanger to pass through; thethird opening 212 is used for filling or draining thefirst fluid 206 into or out of the firstclosed cavity 205 by a siphon effect. Thethird opening 212 is closer to the end of the other side of thefirst sash 101 than thesecond opening 211, so that thefirst fluid 206 is not blocked by the outlet-sidevertical connection pipe 304 passing through thesecond opening 211 when filling or discharging the firsthermetic cavity 205.

Preferably, thethird opening 212 is open except for filling or draining thefirst fluid 206 and is sealed with asoft plug 215 for the remaining time to prevent evaporative loss of thefirst fluid 206. The siphon effect is achieved by using a connecting pipe, such as a plastic hose, inserted into the bottom of the first sealedcavity 205 through thethird opening 212, and thefirst fluid 206 flows from the side with high pressure to the side with low pressure by virtue of the attractive force and potential energy difference existing between the molecules of thefirst fluid 206. When the firstclosed cavity 205 is filled with thefirst fluid 206, the external container for storing thefirst fluid 206 is arranged at a height higher than the liquid flow window, and thefirst fluid 206 automatically flows to the firstclosed cavity 205 from the higher container; when thefirst fluid 206 is discharged from the first sealedcavity 205, the external container for storing thefirst fluid 206 is positioned at a height lower than the flow window, and thefirst fluid 206 automatically flows from the upper intelligent flow window to the external container for storing thefirst fluid 206. Since the inlet (the first opening 210) and the outlet (the second opening 211) of the firstclosed cavity 205 of the flow window are both arranged on thefirst window frame 101 positioned at the upper part of the window; thefirst fluid 206 in the firstclosed cavity 205 has density difference generated by temperature difference under the irradiation of the sun, and then flows under the driving of the generated buoyancy lift force, and belongs to natural flow, the flow rate is low, and the pressure generated in the firstclosed cavity 205 is relatively stable; therefore, the liquid leakage risk of the liquid flow window is low, and the service life is long.

In another preferred embodiment, thethird port 212 may also communicate with aport connection pipe 309 for remotely and scalably regulating the fluid in the firstenclosed cavity 205 in an unattended and operational situation. Preferably, the number of thethird openings 212 may also be multiple corresponding to one flow window, and preferably, thethird openings 212 are provided at both the upper portion and the bottom portion of the flow window, that is, onethird opening 212 is opened at the upper sealant 209 (corresponding to the position of the first window frame 101) of the flow window to facilitate filling of thefirst fluid 206, and anotherthird opening 212 is opened at the lower sealant 209 (corresponding to the position of the third window frame 103) of the flow window to facilitate emptying of thefirst fluid 206.

As shown in fig. 4 and 5, the submerged heat exchanger is composed of 5 parts, which are an inlet sidehorizontal connection pipe 301, an inlet sidevertical connection pipe 302, a main body heat exchangehorizontal pipe 303, an outlet sidevertical connection pipe 304, and an outlet sidehorizontal connection pipe 305 in this order. The inlet side horizontal connectingpipe 301 and the outlet side horizontal connectingpipe 305 of the submerged heat exchanger can be installed in series with other intelligent flow windows capable of adjusting fluorescence, so that thesecond fluid 208 is continuously preheated until the temperature of thesecond fluid 208 reaches the temperature set by a user; the inlet sidehorizontal connection pipe 301 and the outlet sidehorizontal connection pipe 305 of the submerged heat exchanger may be insulated moderately using insulation wool to prevent heat loss.

Preferably, the submerged heat exchanger is made of a metal with a relatively high thermal conductivity, such as copper; preferably, the inner side and the outer side of the copper pipe of the immersed heat exchanger can adopt annular fins to enhance heat exchange. The submerged heat exchanger is fixed on the upper part of the firstclosed cavity 205, but is completely shielded by thefirst window frame 101, so that the appearance is not influenced, and the visual field interaction between the indoor space and the outdoor space is not influenced. The immersed heat exchanger is simple to process and low in production cost.

As shown in fig. 6 and 7, the submerged heat exchanger is mounted on thefirst window frame 101. The upper ends of the inlet side vertical connectingpipe 302 penetrating through thefirst opening 210 at the upper part of the firstclosed cavity 205 and the outlet side vertical connectingpipe 304 penetrating through thesecond opening 211 are sleeved with a fixingring 307 for fixing the submerged heat exchanger not to fall under the action of gravity; the lower ends of the main body heat exchangehorizontal pipes 303 of the submerged heat exchanger are sleeved with fixingrings 308, so that the main body heat exchangehorizontal pipes 303 of the submerged heat exchanger are kept at the middle position of the firstclosed cavity 205, and the uniform flowing and stable heat transfer of thefirst fluid 206 in the gaps between the main body heat exchangehorizontal pipes 303 and thefirst glass plate 201 and thesecond glass plate 204 are ensured.

Preferably, the main heat exchangehorizontal tube 303 of the submerged heat exchanger may be made into an elliptical shape, so as to ensure that thefirst fluid 206 has more flowing space at a position close to the outer side of the submerged heat exchanger, thereby enhancing the heat transfer efficiency.

Preferably, the upperend fixing ring 307 and the lowerend fixing ring 308 may be flexible rubber rings.

Preferably, thesecond fluid 208 may be relatively low temperature municipal water, which absorbs heat from thefirst fluid 206 through the submerged heat exchanger, raises its temperature, flows into other intelligent flow windows connected in series, or flows into the heat collection device after reaching a certain temperature. Thelevel line 213 of thefirst fluid 206 in the first sealedcavity 205 is always above the body heat exchanginghorizontal tubes 303 of the submerged heat exchanger, preventing heat transfer deterioration.

The intelligent flow window with adjustable fluorescence of the plasmon suspension liquid of the embodiment 1 can reduce indoor heating and preheat hot water when outdoor temperature is higher than a certain set value, such as summer, so that energy conservation of an air conditioning system and a hot water system in a building is realized. Under the irradiation of the sun, part of the solar radiation is absorbed by thefirst glass plate 201, thesecond glass plate 204 and thefirst fluid 206, thereby raising the temperature of thefirst glass plate 201, thesecond glass plate 204 and thefirst fluid 206. When the temperature of the adjacentfirst glass plate 201 andsecond glass plate 204 is higher than the temperature of thefirst fluid 206, the heat of thefirst glass plate 201 andsecond glass plate 204 will be transferred to thefirst fluid 206 in a heat conducting and convection manner, and the temperature of thefirst fluid 206 is increased by both direct solar radiation and indirect heat transfer of thefirst glass plate 201 andsecond glass plate 204. The elevated temperaturefirst fluid 206 in the firstclosed cavity 205 transfers heat to thesecond fluid 208 through the submerged heat exchanger built into the window.

When multiple flow windows are used in series, thesecond fluid 208 may be continuously heated. Thus, the flow window acts as a solar collector, reducing the energy consumption of the hot water system within the building by preheating thesecond fluid 208. Meanwhile, since thefirst fluid 206 in the firstclosed cavity 205 absorbs part of the solar energy and carries away heat near thefirst glass plate 201 and thesecond glass plate 204, heat entering the room through solar transmission, thermal radiation, thermal convection and the like is reduced, and energy consumption of the air conditioning system in the summer of the room can be reduced accordingly.

Since thefirst fluid 206 in the firstenclosed cavity 205 absorbs a portion of the solar energy and carries away heat adjacent to thefirst glass sheet 201 and thesecond glass sheet 204, the amount of heat returned to the outdoor environment by solar reflection, thermal radiation, thermal convection, and the like is reduced, thereby alleviating the urban heat island effect.

When the outdoor temperature is lower than a certain set value, for example in winter, thefirst fluid 206 in the firstclosed cavity 205 can be discharged from the upper part of the firstclosed cavity 205 under the siphon effect, so that the firstclosed cavity 205 is filled with an air layer, and the intelligent liquid flow window capable of adjusting fluorescence is converted into a hollow glass window, thereby realizing the heat preservation of the building. An inert gas layer can be filled into the firstclosed cavity 205, so that the heat preservation capability of the window in winter is further enhanced. Under the irradiation of the sun, part of the solar radiation is absorbed by thefirst glass plate 201 and thesecond glass plate 204, thereby raising the temperature of thefirst glass plate 201 and thesecond glass plate 204. Because the thermal conductivity coefficient of the air layer or the multiple air layers in the firstclosed cavity 205 is low, the heat transfer between the indoor and the outdoor is effectively reduced, and the heat preservation effect is achieved. Meanwhile, when thefirst glass plate 201 and thesecond glass plate 204 are multi-layer insulating glass assemblies or low-e glass, the heat preservation capability of the window body is further enhanced.

The intelligent liquid flow window adopting the plasmon suspension for color matching has the solar thermal energy efficiency of not less than 10%, is suitable for integrated application of solar energy and buildings, and promotes the development of green buildings and low-carbon buildings. The intelligent liquid flow window adopting plasmon suspension for color matching provides a new idea for large-area utilization of solar energy in a building under the condition of satisfying the aesthetic conditions of the building.

The intelligent flow window comprises a plurality of plasmon suspensions in the embodiment 1, which are sequentially arranged or arrayed, and an array of 1 row and 3 columns is exemplarily shown in fig. 8.
