Technical Field

[0001] The present application relates to the field of building enclosure systems, and in particular to a prefabricated photovoltaic integrated panel and an assembled photovoltaic enclosure system containing a moisture management system. Background Art

[0002] As an important part of a building, the enclosure structure is the main component that separates the indoor and outdoor areas. The traditional enclosure structure is mainly composed of masonry or reinforced concrete, and has the functions of protection, wind and rain protection, and heat insulation.

[0003] In recent years, more and more enclosure structures are made of functional prefabricated integrated panels. At the same time, in order to adapt to social development and improve the comfort, durability and functionality of buildings, various multifunctional enclosure structures have been developed and used one after another, and the enclosure structure has also risen from a single structure to a multi-layered system. For example, a multifunctional enclosure system composed of decorative panels, insulation panels, waterproof and breathable cloth, porous panels and fireproof panels has multiple functions such as aesthetics, heat insulation, waterproofing, moisture removal, heat preservation, soundproofing and fire prevention, thus giving the building better quality.

[0004] At present, with the development of society and the improvement of human living standards, new requirements have been put forward for enclosure systems, and energy conservation and emission reduction have become new demands; however, conventional enclosure systems have weak energy conservation and emission reduction capabilities; therefore, improving the energy conservation and emission reduction performance of enclosure systems has become a research focus. Summary of the invention

[0005] In order to improve the energy-saving and emission-reduction function of the enclosure system, the present application provides a prefabricated photovoltaic integrated panel and an assembled photovoltaic enclosure system including a moisture management system.

[0006] In the first aspect, a prefabricated photovoltaic integrated panel with a moisture management system is provided, which adopts the following technical solution:

[0007] The prefabricated integrated photovoltaic panel with a moisture management system comprises a stacked solar photovoltaic panel and a moisture management system; the moisture management system comprises an isobaric rainproof curtain wall and a waterproof and breathable cloth, and the isobaric rainproof curtain wall is connected to the solar photovoltaic panel.

[0008] By adopting the above technical solution, solar photovoltaic panels can be used as structural decorative panels and can also use solar energy to generate electricity; the electricity generated can not only be used for the building where it is located, but also can be exported to the power grid, saving equipment materials and electricity costs, reducing the energy consumption and environmental damage caused by conventional power generation, and having the effect of energy saving and emission reduction; and the integration of buildings and photovoltaics reduces the cost of secondary installation. The moisture management system can play a role in waterproofing and dehumidification, and can reduce the accumulation of moisture in the prefabricated photovoltaic integrated panels containing the moisture management system (hereinafter referred to as prefabricated photovoltaic integrated panels), thereby reducing the problem of performance degradation of solar photovoltaic panels due to moisture, and plays a role in protecting solar photovoltaic panels; at the same time, it also enables the entire enclosure system using the prefabricated photovoltaic integrated panels to maintain high performance, so that the thermal insulation performance of the enclosure system is long-term and efficient, and plays an important role in the safety of the enclosure system.

[0066] The following is combined with Figure 1-10 This application is described in further detail.

[0067] Example 1

[0068] This embodiment discloses a prefabricated photovoltaic integrated panel 100 including a moisture management system, which is suitable for the reconstruction of an existing wall or roof. Figure 1 and Figure 2 The prefabricated photovoltaic integrated panel 100 including a moisture management system (hereinafter referred to as the prefabricated photovoltaic integrated panel 100) includes a solar photovoltaic panel 1, an integrated frame 3, and an insulation board 4 installed in the integrated frame 3, a moisture management system 2 and a first structural board 5; the insulation board 4, the moisture management system 2 and the first structural board 5 are stacked together in sequence; the solar photovoltaic panel 1 is connected to the outside of the integrated frame 3 and is adjacent to the insulation board 4.

[0069] Reference Figure 2 and Figure 3 The moisture management system 2 is composed of an isobaric rainproof curtain wall 21 and a waterproof and breathable cloth 22 which are overlapped and connected to each other; at the same time, the isobaric rainproof curtain wall 21 is also connected to the insulation board 4, and the waterproof and breathable cloth 22 is also connected to the first structural board 5. The isobaric rainproof curtain wall 21 includes two layers of base 211, two layers of glass fiber mesh 214 and a plurality of protrusions 212; the two layers of base 211 are both rectangular XPE (chemical cross-linked polyethylene foam material) plates and are arranged in parallel; the two layers of glass fiber mesh 214 correspond to the two layers of base 211 one by one and are superimposed on the inner side of the corresponding base 211 (the side facing between the two bases 211 is the inner side); the protrusion 212 is cylindrical, and its two ends are respectively connected vertically to the two glass fiber meshes 214, and a plurality of protrusions 212 are arranged in a matrix between the two glass fiber meshes 214; the material of the protrusion 212 is the same as that of the base 211 (i.e., both are XPE), and the base 211, the glass fiber mesh 214 and the protrusion 212 are connected together by hot-melt bonding. The waterproof and breathable cloth 22 is a rectangular structure and is connected to the base 211 near the first structural plate 5 by nailing.

[0070] Reference Figure 2 and Figure 3, due to the setting of the protrusion 212 between the two layers of glass fiber mesh 214, a gap 213 is formed between the two glass fiber meshes 214, that is, between the two base layers 211. The gap 213 can provide a space for the water and moisture in the prefabricated photovoltaic integrated panel 100 to be discharged; wherein, the water can overcome the capillary action at the gap 213, and flow downward along the gap 213 under the driving action of gravity and be discharged; the moisture will be taken away by the air blown into the gap 213 from bottom to top. Moreover, the pressure in the gap 213 is equal to or approximately equal to the external pressure, which can effectively prevent the external moisture from penetrating through the wind pressure. In addition, the gap 213 can also block the migration path of water and moisture in the prefabricated photovoltaic integrated panel 100. Therefore, the setting of the gap 213 can play a role in moisture removal and water blocking, reduce the accumulation of moisture in the prefabricated photovoltaic integrated panel 100, not only reduce the damage of moisture to the mechanical structure of the prefabricated photovoltaic integrated panel 100, but also reduce the influence of moisture on the performance of the solar photovoltaic panel 1. At the same time, the gap 213 forms a broken bridge structure in the prefabricated photovoltaic integrated panel 100, which hinders the movement of heat and sound in the prefabricated photovoltaic integrated panel 100, thereby also playing the role of heat insulation and sound insulation. Therefore, the setting of the gap 213 makes the prefabricated photovoltaic integrated panel 100 have high performance and long-term high thermal insulation efficiency.

[0071] In addition, XPE has a uniform pore structure, which is conducive to further improving the heat insulation and sound insulation effect of the prefabricated photovoltaic integrated panel 100. In some other embodiments, the material of the protrusion 212 can also be selected from IXPE, EVA, PU, ​​PP, PVC, ECB (ethylene copolymer modified asphalt). At the same time, the base layer 211 can also be selected from IXPE (electron radiation cross-linked polyethylene foam material) board and waterproof and breathable cloth.

[0072] Reference Figure 2 The solar photovoltaic panel 1 is a rectangular panel, and the solar photovoltaic panel 1 is also equipped with wires and photovoltaic system connectors and other equipment; in this embodiment, these equipment are all conventional structures, so they are not expanded here. The heat insulation board 4 is a rectangular board with the same length and width as the base layer 211, which is specifically a graphite polystyrene board with good heat insulation and heat preservation effects; of course, in other embodiments, the heat insulation board 4 can also be selected from rock wool board, glass fiber insulation wool board or aerogel board.

[0073] Reference Figure 2, the first structural board 5 has the same length and width as the base layer 211. In this embodiment, the first structural board 5 is specifically a gypsum board with a heat-insulating and sound-proofing cushion layer 51 on the surface away from the moisture management system 2; since gypsum has a porous structure, the first structural board 5 in this embodiment can also improve the heat-insulating and sound-proofing effect of the prefabricated photovoltaic integrated panel 100; in addition, gypsum is also non-flammable, so the first structural board 5 can also give the prefabricated photovoltaic integrated panel 100 fireproof performance. In other embodiments, the first structural board 5 can also be selected from cement fiberboard, magnesium crystal board, OSB board or other conventional structural boards with a heat-insulating and sound-proofing cushion layer 51 on one side surface.

[0074] Reference Figure 2 The integrated frame 3 is a rectangular frame surrounded by L-shaped metal strips, and its length and width are the same as those of the solar photovoltaic panel 1; the heat insulation board 4, the moisture management system 2 and the first structural board 5 (including the heat insulation and sound insulation pad 51) are installed in the integrated frame 3 in sequence and fixed by bolts; the solar photovoltaic panel 1 is fixed by bolts on the outer surface of the side of the integrated frame 3 close to the heat insulation board 4, so that the components of the prefabricated photovoltaic integrated panel 100 are integrated into one. A plurality of air-permeable and moisture-discharging holes 31 are provided on the frame strips on the upper and lower sides of the integrated frame 3 (i.e., the upper and lower sides of the rectangular frame); these air-permeable and moisture-discharging holes 31 are arranged equidistantly along the length direction of the frame strips, and are all directly opposite to the gap 213 of the isobaric rainproof curtain wall 21, so that the moisture and water in the gap 213 can be easily discharged.

[0075] The implementation principle of the prefabricated photovoltaic integrated panel 100 with a moisture management system in this embodiment is as follows: the solar photovoltaic panel 1, the heat insulation panel 4, the moisture management system 2 and the first structural panel 5 are arranged in sequence from outdoor to indoor, and integrated into a rectangular panel body through the integrated frame 3. Among them, the solar photovoltaic panel 1 is located at the outermost side of the prefabricated photovoltaic integrated panel 100, which can be used as a structural finishing layer and can also be used to convert light energy into electrical energy for use in the building where the prefabricated photovoltaic integrated panel 100 is located or output to the power grid, saving equipment materials and electricity costs; at the same time, the solar photovoltaic panel 1 can also adjust the temperature in the building by absorbing heat. The heat insulation panel 4 plays a role in heat insulation. The setting of the moisture management system 2 is conducive to the role of moisture removal and water blocking, reducing the accumulation of moisture in the prefabricated photovoltaic integrated panel 100, thereby not only helping to reduce the phenomenon that the mechanical properties of the prefabricated photovoltaic integrated panel 100 are damaged by moisture, but also reducing the problem of performance degradation of the solar photovoltaic panel 1 due to moisture; at the same time, the moisture management system 2 can also play the role of heat insulation, sound insulation and noise reduction. The first structural panel 5 can play a supporting role and also can give the prefabricated photovoltaic integrated panel 100 better fireproof, heat-insulating and noise-reducing performance.

[0076] Example 2

[0077] This embodiment discloses a prefabricated photovoltaic integrated panel 100 including a moisture management system. Figure 4 and Figure 5 This embodiment is basically the same as the embodiment 1, the main difference being that the prefabricated integrated photovoltaic panel 100 in this embodiment is suitable for new construction of a wall; therefore, the prefabricated integrated photovoltaic panel 10 with a moisture management system in this embodiment comprises a solar photovoltaic panel 1, a moisture management system 2, an integrated frame 3, an insulation panel 4, a first structural panel 5, a keel layer 6, an insulation layer 7, and a second structural panel 8. At the same time, the first structural panel 5 is not provided with an insulation and sound insulation cushion layer 51.

[0078] Reference Figure 4 and Figure 5 , the solar photovoltaic panel 1, the heat insulation panel 4, the moisture management system 2, the first structural panel 5, the keel layer 6 and the second structural panel 8 are arranged in sequence from the outdoor to the indoor. In addition, the heat insulation panel 4, the moisture management system 2 and the first structural panel 5 are sequentially installed in the integrated frame 3 and fixed with bolts; the solar photovoltaic panel 1 is located outside the side of the integrated frame 3 close to the heat insulation panel 4, and is fixed to the integrated frame 3 by means of bolts, and the keel layer 6 is located outside the side of the integrated frame 3 close to the first structural panel 5, and is fixed to the integrated frame 3 by means of bolts; the second structural panel 8 is fixed to the keel layer 6 on the side away from the integrated frame 3 by means of bolts, and the center of the second structural panel 8 is collinear with the center of the keel layer 6; the second structural panel 8 is coated with a paint finish on the side away from the keel layer 6 (i.e., the side facing the indoors).

[0079] Reference Figure 5 , the keel layer 6 is a rectangular plate-shaped frame structure, and its length and width are the same as those of the integrated frame 3; the keel layer 6 is composed of a plurality of keels 61 arranged in an arrangement. The keel 61 is a C-shaped lightweight keel, and its inner side has a wiring cavity for the wiring of the solar photovoltaic panel 1. The thermal insulation layer 7 is filled in the frame structure formed by the plurality of keels 61. In this embodiment, the material of the thermal insulation layer 7 is graphite polystyrene, which has good thermal insulation properties; in some other embodiments, the material of the thermal insulation layer 7 can also be a combination of one or more of aerogel, rock wool, XPE foam, and IXPE foam. The second structural board 8 is a rectangular board. In order to be placed in a prefabricated building structure frame during installation, the length and width of the second structural board 8 are smaller than the keel layer 6. In this embodiment, the second structural board 8 is specifically a gypsum board; in other embodiments, the second structural board 8 can also be a cement fiber board, a magnesium crystal board or other conventional structural boards with fire resistance.

[0080] The keel layer 6 and the second structural plate 8 cooperate with the first structural plate 5 to form a skin effect, which increases the overall mechanical strength and structural stability of the prefabricated photovoltaic integrated panel 100, improves the bearing capacity of the prefabricated photovoltaic integrated panel 100, and enables the prefabricated photovoltaic integrated panel 100 to be used independently as a wall panel. The provision of the thermal insulation layer 7 improves the thermal insulation of the prefabricated photovoltaic integrated panel 100, thereby improving the comfort of the constructed building.

[0081] Example 3

[0082] This embodiment discloses a prefabricated photovoltaic integrated panel 100 including a moisture management system. Figure 6 and Figure 7 This embodiment is basically the same as Embodiment 2, the main difference being that the prefabricated photovoltaic integrated panel 100 in this embodiment is mainly used in severely cold regions, so the prefabricated photovoltaic integrated panel 100 in this embodiment also includes an air barrier film 9; specifically: the prefabricated photovoltaic integrated panel 100 is composed of a solar photovoltaic panel 1, a moisture management system 2, an integrated frame 3, an insulation board 4, a first structural panel 5, a keel layer 6, an insulation layer 7, a second structural panel 8 and an air barrier film 9.

[0083] Reference Figure 6 and Figure 7 The air barrier film 9 is rectangular in shape, and its length and width are the same as those of the second structural plate 8. The air barrier film 9 is located between the keel layer 6 and the second structural plate 8, and is connected to the two by bolts. The setting of the air barrier film 9 can effectively prevent moisture from migrating from the room into the prefabricated photovoltaic integrated panel 100, reduce the moisture content in the prefabricated photovoltaic integrated panel 100, and thus reduce the influence of moisture on the structural strength of the prefabricated photovoltaic integrated panel 100 and the performance of the solar photovoltaic panel 1.

[0084] Example 4

[0085] This embodiment discloses an assembled photovoltaic enclosure system, which is a modification of an existing building wall. Figure 8 The assembled photovoltaic enclosure system includes the prefabricated photovoltaic integrated panel 100 disclosed in Example 1, the wall layer 200 and the flashing board 300.

[0086] Reference Figure 8 The wall layer 200 is an existing wall; a plurality of prefabricated integrated photovoltaic panels 100 are arranged and are installed in a matrix on the outer surface of the wall layer 200 through a lightweight installation keel 201 .

[0087] A plurality of prefabricated photovoltaic integrated panels 100 form a curtain wall with the function of utilizing solar energy to generate electricity on the outer surface of the wall layer 200, which can not only provide electricity for existing buildings, but also generate energy, and also save the racks and installation equipment of the traditional photovoltaic system, reducing the energy consumption and environmental pollution caused by traditional power generation; at the same time, because the solar photovoltaic panel 1 has the function of absorbing solar energy, it can also adjust the indoor temperature and reduce the pressure and energy consumption of the air conditioner; therefore, the assembled photovoltaic enclosure system improves the effect of energy saving and emission reduction due to the curtain wall. At the same time, the curtain wall formed also has the functions of moisture removal and water blocking, thermal insulation, fire prevention and sound insulation, etc., which is conducive to further improving the high performance of the assembled photovoltaic enclosure system, thereby improving the comfort of the existing buildings.

[0088] Reference Figure 8 The flashing board 300 is a long strip, and its length is the same as the long side of the prefabricated photovoltaic integrated panel 100; the flashing board 300 also has a water-guiding folding edge 301 at its long side. A flashing board 300 is horizontally arranged below each prefabricated photovoltaic integrated panel 100; specifically, the flashing board 300 is connected to the bottom of the corresponding prefabricated photovoltaic integrated panel 100 through a mounting block, and there is a gap therebetween; at the same time, the flashing board 300 also has a gap with the prefabricated photovoltaic integrated panel 100 (if any) below it. The existence of the gap can prevent the air-permeable and moisture-draining hole 31 from being blocked, so that the gap 213 is connected to the outside world, and moisture and water can be discharged smoothly. At the same time, the setting of the flashing board 300 makes the gap 213 have a certain degree of independence, reduces the power of external rainwater to migrate into the prefabricated photovoltaic integrated panel 100 through the gap 213 under the action of wind pressure, and improves the ability of the prefabricated photovoltaic integrated panel 100 to prevent wind and rain penetration.

[0089] It should be noted that the upper ventilation and moisture removal holes 31 of the top prefabricated photovoltaic integrated panel 100 can be covered by a roof or cover plate (maintaining a certain gap) to prevent rainwater from directly pouring into the gap 213. In addition, the wires of the solar photovoltaic panel 1 can be routed in the lightweight installation keel 201.

[0090] Example 5

[0091] This embodiment discloses an assembled photovoltaic enclosure system. Fig. 9 This embodiment is basically the same as Embodiment 4, the main difference being that the assembled photovoltaic enclosure system in this embodiment is a modification of the roof of an existing building; therefore, the assembled photovoltaic enclosure system in this embodiment includes the prefabricated photovoltaic integrated panel 100, the roof body 500 and the flashing board 300 disclosed in Embodiment 1.

[0092] Reference Fig. 9, the roof body 500 is an existing structure and is in the shape of a sloping roof. A plurality of prefabricated photovoltaic integrated panels 100 are arranged and evenly installed on the outer surfaces of the inclined surfaces on both sides of the roof body 500 through lightweight mounting keels 201; the prefabricated photovoltaic integrated panels 100 located on the same side of the inclined surface are arranged in a matrix, thereby forming a multifunctional curtain wall on the surface, which can not only generate electricity and supply power and adjust the room temperature, but also play the role of moisture removal and water blocking, heat preservation and insulation, fire prevention and sound insulation, thereby giving the assembled photovoltaic enclosure system more functionality. In addition, the long strip of flashing board 300 is horizontally arranged below each prefabricated photovoltaic integrated panel 100, and there is a gap between the flashing board 300 and the prefabricated photovoltaic integrated panels 100 above and below it; and a ridge cover plate and an air vent are arranged at the adjacent parts of the two curtain walls of the same roof body 500 (i.e., the top of the roof).

[0093] In addition, it should be noted that if the roof body 500 is flat, the assembled photovoltaic enclosure system does not need to install the flashing board 300, and it is sufficient to ensure that there is a gap between the two adjacent prefabricated photovoltaic integrated panels 100 and that the air permeability and moisture removal holes 31 are not blocked. At the same time, if it is a flat-top structure, although the moisture removal performance of the moisture management system 2 in the prefabricated photovoltaic integrated panel 100 will be limited and deteriorated, it can still solve the technical problem.

[0094] Example 6

[0095] This embodiment discloses an assembled photovoltaic enclosure system. Fig.10 This embodiment is basically the same as Embodiment 4, the main difference being that the assembled photovoltaic enclosure system in this embodiment is used in the walls of newly constructed buildings; therefore, the assembled photovoltaic enclosure system in this embodiment includes the prefabricated photovoltaic integrated panel 100, the building structure frame 400 and the flashing board 300 disclosed in Embodiment 3.

[0096] Reference Fig.10 The building structure frame 400 is a steel structure frame, which is composed of vertical bars and horizontal bars; the prefabricated photovoltaic integrated panels 100 are arranged in a matrix and connected to the building structure frame 400. Specifically, the keel layer 6 of the prefabricated photovoltaic integrated panels 100 is fixed to the building structure frame 400 by bolts; the second structural panel 8 and the air barrier film 9 of the prefabricated photovoltaic integrated panels 100 are located in the gap surrounded by the vertical bars and horizontal bars of the building structure frame 400.

[0097] Through the above connection, multiple prefabricated photovoltaic integrated panels 100 are based on the building structure frame 400 to form a wall with the function of utilizing solar energy for power generation; the wall can not only generate electricity by itself to provide electricity for the building, but also output it to the power grid, thereby improving the energy-saving and emission-reduction function of the assembled photovoltaic enclosure system; at the same time, the wall can also improve the moisture-draining and water-blocking, thermal insulation, fire-proof and sound-proof functions of the assembled photovoltaic enclosure system, which is beneficial to improving the comfort of the constructed building.

[0098] Reference Fig.10 The flashing plate 300 is a long strip plate and is horizontally installed below each prefabricated photovoltaic integrated panel 100. Specifically, the flashing plate 300 is installed on the building structure frame 400 below the corresponding prefabricated photovoltaic integrated panel 100, and there is a gap between the flashing plate 300 and the corresponding prefabricated photovoltaic integrated panel 100; at the same time, there is a gap between the flashing plate 300 and the prefabricated photovoltaic integrated panel 100 (if any) below it. The existence of the gap prevents the air permeability and moisture removal holes 31 from being blocked, so that the gap 213 remains connected to the outside world.

[0099] Compared to the prefabricated photovoltaic enclosure system of Example 4, the prefabricated photovoltaic enclosure system of Example 6 has lower design and installation costs because it is included in the initial design of the building and replaces standard building materials during construction.
