Description

Technical Field

[0001] The invention relates to the field of building photovoltaic integration, and in particular to an integrated design system for building glass curtain wall photovoltaic components. Background Art

[0002] BIPV (Building Integrated PV, PV stands for Photovoltaic) is a new practical technology that highly integrates solar photovoltaic components with building envelope structures. It is the source of future distributed power supply and one of the key technologies for cross-innovation in the energy field and urban construction field. In the past 10 years, solar photovoltaic products have developed rapidly. The types of materials have developed from crystalline silicon, copper indium gallium selenide, cadmium telluride to perovskite. The energy conversion efficiency has increased from 12% to 35%. The cost of similar products has dropped by 15%, and the appearance, stability, and product size diversity of solar photovoltaic products have been significantly improved. This provides a technical basis for the appropriate application of solar products to building envelope structures.

[0003] Conventional crystalline silicon photovoltaic modules are installed in a closed manner. After the crystalline silicon photovoltaic panel is sealed and installed, the cavity formed between the rear metal backplane and the insulation rock wool is a completely closed space. Under normal working conditions, the crystalline silicon photovoltaic module generates a large amount of heat during the day. The cavity temperature between the photovoltaic module and the insulation and interlayer fire protection system is 20-25℃ higher than the ambient temperature. In summer, under high temperature and strong light conditions, the cavity temperature can reach 70℃. The heat cannot be dissipated in time, affecting the normal operation of the crystalline silicon photovoltaic module and posing a fire hazard. At the same time, high temperature will also cause the output power of the photovoltaic module to decrease, affecting the performance of the module, and even accelerating the aging of the organic materials of the module. In addition, high temperature will also affect the heat dissipation efficiency of the inverter, which may cause its performance to decline, and then affect the stability of the entire photovoltaic system. Long-term high-temperature operation may cause PID phenomenon, battery power attenuation, and seriously affect the service life of photovoltaics. Since photovoltaic modules do not have insulation performance, photovoltaic modules need to be combined with insulation components to achieve the insulation performance of the maintenance structure. If the gaps between photovoltaic modules and between photovoltaic modules and glass curtain walls are not handled properly, they may cause water seepage and leakage or even structural damage due to long-term rain erosion.

[0004] Therefore, BIPV technology currently faces compatibility issues such as how to balance fire prevention and power generation, thermal insulation and heat dissipation. At the same time, there are also issues such as how photovoltaic modules and external curtain wall systems can comprehensively solve the problems of thermal insulation, fire prevention, waterproofing, and power generation, as well as how to ensure functional stability and safety.

Please note that in order to clearly show the structures of various components of the embodiments of the present invention, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not used to limit the scope of the present invention. Figure 1-6 , the preferred embodiments of the present invention are further described in detail: A building glass curtain wall photovoltaic assembly integrated design system comprises a keel unit 1, a glass curtain wall assembly 2, a crystalline silicon photovoltaic curtain wall assembly 3 and a thin film photovoltaic curtain wall assembly 4, wherein the keel unit 1 is fixedly arranged on a main structure of a building, the glass curtain wall assembly 2 is arranged on the keel unit 1 and is located at an indoor lighting position, the crystalline silicon photovoltaic curtain wall assembly 3 is arranged at a building interlayer floor position between two adjacent keel units 1 on an upper and lower layer, the thin film photovoltaic curtain wall assembly 4 is fixedly arranged on the keel unit 1 and is located at an indoor lighting position and is spaced apart from the glass curtain wall assembly 2 on the same layer, the keel unit 1 is provided with a cable channel, the crystalline silicon photovoltaic curtain wall assembly 3 is provided with an air flow channel, and a waterproof device is provided at the interface of the air flow channel.

[0025] The keel unit 1 includes a transverse keel 101 and a vertical keel 102, which are fixed to the main structure of the building through embedded parts. This embodiment is a vertically visible and horizontally hidden curtain wall, that is, the vertical keel 102 is fixed to the main structure of the building through embedded parts, and the transverse keel 101 is fixed between two adjacent vertical keels 102 to complete the installation of the keel unit 1; the glass curtain wall group 2 is a conventional component, including curtain wall glass, sealing material and fixing device. The curtain wall glass is fixed to the keel unit 1 through the fixing device, and the surrounding side of the curtain wall glass is sealed with a sealing material to realize the installation of the glass curtain wall assembly 2. The curtain wall glass in this embodiment uses hollow double-layer glass.

[0026] The crystalline silicon photovoltaic curtain wall assembly 3 includes a crystalline silicon photovoltaic panel 301, a frame 302, and a front lining plate 307. The front lining plate 307 is fixed on the keel unit 1. A thermal insulation material 13 is arranged on the side of the front lining plate 307 close to the interior of the building. In order to solve the heat dissipation problem and facilitate maintenance and replacement, the crystalline silicon photovoltaic curtain wall assembly 3 adopts a hanging setting method. The front lining plate 307 adopts a 3mm fluorocarbon sprayed aluminum single plate, and the main body is grooved. The frame 302 is hung on the side of the vertical keel 102, and a cavity 305 is formed between the main body and the front lining plate 307. Specifically, a crystalline silicon photovoltaic panel 301 is arranged on the inner side of the frame 302, and three reserved notches 6 are arranged on each side of the frame 302. The shape of the reserved notches 6 is L-shaped, and a hanging member 7 is arranged on each side of the vertical keel 102 at a position corresponding to the reserved notch 6. The hanging member 7 is made of aluminum alloy hanging member 7, and an adjustable nut is installed on each hanging member 7, and the hanging member 7 is welded to the vertical keel 102 of the curtain wall. The crystalline silicon photovoltaic panel (301) and the frame (302) have been assembled in the factory and transported to the site for hanging. During installation, the L-shaped notch on the frame 302 is aligned with the hanging member 7, and the frame 302 is pushed into the groove of the front lining 307, and is stuck with the hanging member 7 by gravity. After the frame 302 is hung on the hanging member 7 and fixed firmly, the gap on the left and right sides of the frame 302 is adjusted by rotating the nut, and finally it is tightened and fixed with bolts. In this way, a 75mm wide cavity 305 is formed between the crystalline silicon photovoltaic panel 301 and the front lining 307, so that the photovoltaic module is easy to install and repair. When any component is damaged, it can be replaced in time, avoiding the reduction of the overall system efficiency, ensuring the stability of the photovoltaic system, and realizing the heat dissipation of the photovoltaic module.

[0027] At the same time, in order to solve the fire prevention function of the system, fireproof materials are used for sealing. The gap between the curtain wall and the main structure of the building is often sealed with rock wool for fire prevention. By separating the upper and lower floors, smoke is prevented from running up and down between floors. According to the requirements of 6.2.5 of the Code for Fire Protection Design of Buildings (2018 Edition): A solid wall with a height of not less than 1.2m or a fire-proof cantilevered eave with a width of not less than 1.0m and a length not less than the width of the opening should be set between the upper and lower openings on the exterior wall of the building; when an automatic sprinkler fire extinguishing system is installed indoors, the height of the solid wall between the upper and lower openings should not be less than 0.8m. Therefore, when an automatic sprinkler fire extinguishing system is installed indoors, the upper and lower fire blocking distance should not be less than 800mm. Therefore, a backing plate 308 is attached to the outside of the structural beam, and the backing plate 308 is fixed to the transverse keel 101 by screws to replace the building exterior wall. The purpose of this is to reduce the thickness of the external maintenance structure and increase the usable area while keeping the building area unchanged. The backing plate 308 is made of 1.5 mm galvanized steel plate. A support plate 14 is set between the backing plate 308 and the structural beam. The support plate 14 is fixed between the structural beam and the backing plate 308 by connecting bolts 9. The upper blockage is anchored between the floor edge and the backing plate 308 by the support plate 14. The support plate 14 is 1.5 mm thick fireproof galvanized steel plate. Zinc steel plate, the support plate 14 supports 200mm thick fireproof rock wool, and the upper surface of the fireproof rock wool is covered with fireproof sealing paint; the lower sealing adopts the support plate 14 to be anchored between the outer side of the structural beam and the backing plate 308, the support plate 14 is a 1.5mm thick fireproof galvanized steel plate, and the support plate 14 supports 200mm thick fireproof rock wool. The gap between the support plate 14 and the structural beam is sealed with fireproof glue, and the surface of the rock wool is coated with fireproof glue not less than 3mm thick, and the fireproof glue is sealed. The fireproof grade is A, the density is not less than 110kg / m³, and the fireproof rock wool is pre-compressed by at least 20% for dense filling.

[0028] The main flammable point inside the BIPV curtain wall system is the power cable of the photovoltaic module. Therefore, the design requires that the power cable laid in the curtain wall keel cavity 305 should meet the laying environment requirements of -10℃-55℃, and play an effective fire-resistant and flame-retardant role. In order to better achieve ventilation and heat dissipation, an air groove 304 is formed between the upper and lower ends of the frame 302 and the front lining 307. When the solar radiation heat is absorbed by the crystalline silicon photovoltaic curtain wall component 3, the temperature in the cavity rises rapidly. As the temperature in the cavity increases, the air with a lower external temperature flows in from the bottom air groove 304, forms convection in the cavity 305, and flows out from the top air groove 304, taking away a large amount of heat, thereby reducing the ambient temperature of the crystalline silicon photovoltaic curtain wall component 3 during operation, reducing the impact of high temperature on component performance, reducing the risk of spontaneous combustion of materials, and avoiding fire hazards.

[0029] In order to better waterproof, drip eaves 306 are set at the upper and lower ends of the front lining plate 307. The drip eaves 306 are connected to the front lining plate 307 by a rivet structure. A 20mm gap is left between the drip eaves 306 and the upper and lower ends of the frame 302 to form an air groove 304, and the frame 302 is selected for a certain length. The drip eaves 306 are set to an eagle's beak shape with a triangular cross-section, and the inclination angle of the drip eaves 306 is set to 30°. The advantage of this setting is that the triangle has good stability and can reduce material costs. Selecting a certain length of the frame 302 can prevent rainwater from the outer curtain wall from flowing back along the crystalline silicon photovoltaic panel 301 into the ventilation cavity 305, so that the aesthetics and functional performance are organically combined; the bottom of the air groove 304 is set with an external guide inclination angle of 1%, which can make the scattered rainwater entering the cavity 305 of the photovoltaic module be discharged smoothly. At the same time, the 30° acute-angle drip eaves 306 below the bottom of the air groove 304 can drain the rainwater left by the outer curtain wall in time. At the same time, the front lining board 307 using fluorocarbon sprayed aluminum plate is light in weight, has good waterproof and weather resistance, and combined with the rock wool board, it can ensure the long-term stability and safety of the insulation system.

[0030] In order to improve the thermal insulation performance of the curtain wall system, the glass curtain wall component 2 adopts hollow double-layer glass, the hollow part is filled with inert gas 16, and the inert gas 16 can be argon. The keel unit 1 adopts a heat-insulating broken bridge aluminum alloy profile, and is filled with a polyurethane foaming agent. The end of the keel unit 1 is provided with a buckle cover 8, and a decorative pressing plate 12 is provided between the keel unit 1 and the buckle cover 8. The crystalline silicon photovoltaic curtain wall component 3 is an opaque component and is used in the floor position between the building layers. The front lining plate 307 and the back lining plate 30 The setting of the thermal insulation material 13 between 8 can make the curtain wall frame form a continuous thermal insulation interface to avoid the generation of thermal bridges. The thermal insulation material 13 adopts a 100mm thick rock wool board coated with single-sided aluminum foil with a thermal conductivity of no more than 0.04W / mk. The thermal insulation material 15 is laid in the gap between the lateral groove of the front lining plate 307 and the vertical keel 102. The thermal insulation material 15 adopts a 10mm thick insulation blanket. At the same time, the fireproof material is supported on the supporting plate 14, which can also well ensure the thermal insulation effect.

[0031] A thin-film photovoltaic curtain wall component 4 is used to replace part of the glass curtain wall component 2. The thin-film photovoltaic curtain wall component 4 uses a component with a light transmittance of 60%, and there is no line of sight obstruction. The thin-film photovoltaic curtain wall component 4 can replace the glass curtain wall component 2 as needed. A commonly used setting method is to set the thin-film photovoltaic curtain wall component 4 and the glass curtain wall component 2 at intervals, such as setting one interval per interval, setting one interval per two intervals, etc. This solution will not cause line of sight obstruction in the indoor space, and can maximize the laying amount of photovoltaic components while meeting the indoor lighting requirements. The thin film photovoltaic curtain wall assembly 4 is relative to the traditional crystalline silicon photovoltaic curtain wall assembly 3. Compared with the crystalline silicon photovoltaic curtain wall assembly 3, the material of the thin film photovoltaic curtain wall assembly 4 is thinner and more flexible. In order to maintain the good thermal insulation performance of the building curtain wall system, the thin film photovoltaic curtain wall assembly 4 adopts a hollow cadmium telluride thin film photovoltaic curtain wall assembly 4. Through laser scribing, the light transmittance can be adjusted, the light transmittance is uniform, and the color is rich. It can fully meet the requirements of building beauty and can directly replace the glass curtain wall. Even under low light and high temperature conditions, the thin film photovoltaic curtain wall assembly 4 can maintain good power generation performance. The unit width of the thin film photovoltaic curtain wall assembly 4 is 1200mm and the total height is 2100mm. The maximum size of the existing technology is 1200mm*1800mm. Therefore, the assembly unit is designed to be divided into upper plates of 1200mm*900mm and lower plates of 1200mm*1200mm. The upper and lower units are divided by the curtain wall transverse keel 101. The thin-film photovoltaic curtain wall component 4 includes a thin-film photovoltaic component 401, a spacer 402 and a tempered glass 403. The thin-film photovoltaic component 401 and the tempered glass 403 are arranged in parallel on the inner side of the keel unit 1, and the arrangement method is bonding. The bonding tool is a PVB sandwich adhesive sheet. The tempered glass 403 is arranged close to the indoor side of the building. A spacer 402 is arranged between the thin-film photovoltaic component 401 and the tempered glass 403. The spacer 402 is an aluminum hollow square tube filled with molecular sieves. The hollow part between the thin-film photovoltaic component 401 and the tempered glass 403 is filled with an inert gas 16. The inert gas 16 is argon. The thin-film photovoltaic component 401 and the tempered glass 403 are surrounded by a sealant 17. The sealant 17 is a silicone structural sealant. The hollow cadmium telluride thin-film photovoltaic curtain wall component 4 is tightly sealed on all sides by the sealant 17. The installation of the hollow cadmium telluride thin-film photovoltaic curtain wall assembly 4 is similar to that of the glass curtain wall assembly 2. The hollow cadmium telluride thin-film photovoltaic curtain wall assembly 4 is fixed to the keel unit 1, and the surrounding side of the thin-film photovoltaic curtain wall assembly 4 is sealed with a sealant 17. A polyurethane foam filler is filled between the thin-film photovoltaic curtain wall assembly 4 and the keel unit 1.

[0032] In order to solve the power generation problem of the curtain wall system, a junction box 5 is set in the photovoltaic component system. The wiring heads in the crystalline silicon photovoltaic curtain wall component 3 and the thin-film photovoltaic curtain wall component 4 are all led out by the junction box 5. The junction box 5 in the crystalline silicon photovoltaic curtain wall component 3 is set at the cavity 305 between the crystalline silicon photovoltaic panel 301 and the front lining plate 307. The junction box 5 in the thin-film photovoltaic curtain wall component 4 is set in the sealant 17 around the thin-film photovoltaic component 401 and the tempered glass 403. The junction box 5 can adopt a pen-type junction box. The lead-out cable is introduced into the room through the wire trough 10 set on the vertical keel 102, and is connected to the indoor inverter or energy storage battery. A There is a gusset plate 11 made of aluminum alloy. The wire trough 10 and the gusset plate 11 can be used as a transition space for introducing the wiring of the photovoltaic component system into the room, and can also play a role in protecting the cables. The cables are connected in series in the transition space, where every 5 horizontal crystalline silicon photovoltaic curtain wall components 3 are connected in series in sequence to form a string unit, and every 5 horizontal thin-film photovoltaic curtain wall components 4 are connected in series in sequence to form a string unit. The gusset plate 11 is the same width as the vertical keel 102, 3300mm high, the upper end is the same height as the top of the supporting plate 14, and is 30mm deep.
