Description

Technology Field

[0001] The present invention relates to an insulating and ventilated BIPV system, and more specifically, to an insulating and ventilated BIPV system that can increase PV panel efficiency by providing thermal insulation and forming a ventilated airway in a BIPV system installed on the exterior wall of a building. Background Technology

[0002] Building-Integrated Photovoltaics (BIPV) is a technology that simultaneously performs energy production and architectural functions by replacing building exterior materials with power generation modules, and is applied to various parts such as curtain walls, windows, and roofs.

[0003] In these BIPV systems, heat accumulates on the rear of the modules during the power generation process. Although a method is used to introduce outside air through vents, the outside air comes into direct contact with the building's insulation, degrading insulation performance and causing thermal bridging in the frame, making it difficult to meet the insulation requirements of test standards.

[0004] Although double-layer or triple-layer PV modules can be applied without ventilation openings to ensure insulation, they are less economical due to higher costs compared to single-pane PV modules. Furthermore, there are limitations in structural stability due to reduced power generation efficiency caused by thermal cracking and the risk of insulation material damage or detachment.

[0005] In addition, there is a problem in that the construction period is extended due to the complexity of the process of installing PV modules on the exterior walls of buildings, so there is a need to simplify the construction. Prior art literature

Specific details for implementing the invention

[0020] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited to this embodiment and can be modified in various forms.

[0021] In the drawings, parts unrelated to the description have been omitted to clearly and concisely explain the present invention, and the same reference numerals are used for identical or extremely similar parts throughout the specification. Additionally, in the drawings, thicknesses, widths, etc., are depicted enlarged or reduced to make the description clearer; however, the thicknesses, widths, etc., of the present invention are not limited to those depicted in the drawings.

[0022] And when any part of the specification is described as "including" another part, unless specifically stated otherwise, it does not exclude other parts and may include additional parts.

[0024] FIG. 1 is a perspective view showing the overall appearance of an insulating ventilation type BIPV system according to one embodiment of the present invention.

[0025] As illustrated in FIG. 1, an insulating ventilation type BIPV system according to one embodiment of the present invention may be provided between a horizontal member (50) and a vertical member (60), and may include an insulating guide part (100) that insulates the building with an insulating material and has a metal plate bent on one side arranged to form an internal flow path (U), and a PV module part (200) that is spaced apart from the insulating guide part (100), is fixed to the horizontal member (50) and the vertical member (60) to prevent the insulating guide part (100) from falling off, and communicates with the internal flow path (U) through an opening (S) provided at the top and bottom.

[0026] First, the insulation guide section (100) can secure insulation on the rear of the module in a BIPV system applied as an exterior material of a building, and at the same time induce outside air to form a ventilation path inside.

[0027] The insulation guide section (100) can reduce energy loss by insulating the building from the outside air and prevent heat loss by circulating the heat generated on the rear of the module through the internal flow path (U).

[0028] Accordingly, the insulation guide section (100) has the effect of preventing a decrease in power generation efficiency by suppressing overheating of the module while maintaining the building's insulation performance, and preventing damage or detachment of the internal insulation material by forming a ventilation path to stably guide the flow of outside air.

[0029] Next, the PV module section (200) is composed of panels that generate power and frames that support and fix them, and is spaced apart from the insulation guide section (100), and can generate power using sunlight while serving as an exterior material for the building.

[0030] Additionally, the PV module section (200) can be connected to the internal flow path (U) of the insulation guide section (100) through an opening (S) provided at the top and bottom, so that the flow of outside air can circulate along the rear of the solar panel.

[0031] In addition, the PV module section (200) effectively discharges heat from the rear of the module to prevent heat loss, maintains the power generation efficiency of the solar panel stably, and prevents detachment and increases structural stability by having the frame support the insulation guide section (100).

[0032] Here, the frame of the PV module part (200) is formed of a synthetic resin material rather than metal, so that thermal bridging can be effectively blocked and economic efficiency can be secured.

[0033] The insulation guide section (100) and the PV module section (200) are formed as modular types so that they can be easily installed on the exterior wall of a building, and the construction sequence can be such that the insulation guide section (100) is attached to the building first, and then the PV module section (200) is finished.

[0034] Through this, the thermal insulation ventilation type BIPV system according to one embodiment of the present invention is equipped with a thermal insulation guide section (100) to improve the power generation efficiency of the PV module section (200), thereby improving the thermal insulation performance of the building and ventilation performance through the internal flow path (U).

[0035] In addition, the PV module (200) is formed of a synthetic resin material, which effectively blocks thermal bridging in the building, thereby ensuring economic efficiency.

[0036] Even if a single-layer PV panel is applied to the PV module section (200), the insulation guide section (100) and the ventilation structure through the internal flow path (U) work together to secure insulation performance comparable to that of a double-layer or triple-layer PV panel.

[0037] Therefore, the present invention is based on a single-layer PV panel, yet simultaneously satisfies power generation efficiency and thermal insulation performance, and has the effect of ensuring economic efficiency by not using double-layer or triple-layer PV panels that are more than twice as expensive.

[0038] The following describes in more detail the detailed configuration of an insulating ventilation type BIPV system according to one embodiment of the present invention.

[0040] FIG. 2 is a cross-sectional view showing the cross-section of AA in FIG. 1 in detail, and FIG. 3 is a cross-sectional view showing the cross-section of BB in FIG. 1 in detail.

[0041] Referring to FIGS. 2 and 3, the insulation guide section (100) may be provided with a rear insulation material (110) that insulates the building, a gap insulation material (120) that is placed in the gap between the rear insulation material (110) and the PV module section (200) to block thermal bridges, and a guide member (130) that covers the outer edge of the rear insulation material (110) and the gap insulation material (120) to finish the border and forms an internal flow path (U) that communicates with an opening (S) to guide outside air, thereby reducing heat generation of the PV panel (210).

[0042] The rear insulation material (110) is placed on the rear of the building's outer wall to perform basic insulation functions, block heat from entering from the outside, and reduce energy loss in the interior space.

[0043] The rear insulation material (110) can maintain the insulation performance of the entire system by preventing direct contact between the heat generated at the rear of the PV module (200) and the outside air.

[0044] The gap insulation material (120) is placed in the gap between the rear insulation material (110) and the frame of the PV module part (200), and can block thermal bridges from occurring in the fine gaps that occur due to the structure.

[0045] The guide member (130) covers the outer edge of the rear insulation material (110) and the gap insulation material (120) to finish the border, and at the same time forms an internal flow path (U) that communicates with the PV module part (200), and outside air can be introduced through the opening (S) and flow along the internal flow path (U).

[0046] The guide member (130) allows heat from the rear of the module to be effectively discharged and reduces heat generation in the PV module (200), thereby stably maintaining power generation efficiency.

[0047] Next, the PV module section (200) may be provided with a PV panel (210) that generates power using solar energy, a PV fixing bar (220) that wraps around and finishes the perimeter of the PV panel (210), an insulation frame (230) that combines both ends of the PV fixing bar (220) and is fixed to a horizontal member (50) and a vertical member (60) and has improved insulation performance through a hollow portion formed inside, and an opening frame (240) that combines the upper and lower ends of the PV fixing bar (220) and is fixed to the insulation frame (230) and has an opening (S) at the upper and lower ends and has improved insulation performance through a hollow portion formed inside.

[0048] The PV panel (210) serves as an exterior material and generates power using sunlight, and the heat generated at the rear during the power generation process is discharged by the outside air introduced through the opening (S), thereby preventing heat generation and maintaining stable power generation efficiency.

[0049] The PV fixing bar (220) wraps around the perimeter of the PV panel (210) and is connected to the insulation frame (230) and the opening frame (240) to firmly fix the PV panel (210) and prevent deformation and detachment of the panel due to external wind pressure or load.

[0050] The insulation frame (230) is a frame that finishes both ends of the PV panel (210), is fixed to the horizontal member (50) and the vertical member (60), has a hollow portion formed inside to improve insulation performance, and can be formed of a synthetic resin material (PVC, ABS, etc.) instead of metal to block thermal bridges.

[0051] The opening frame (240) is a frame that finishes the upper and lower ends of the PV panel (210) and is fixed to the insulation frame (230). An opening (S) is provided at the upper and lower ends of the PV module section (200) and communicates with the internal flow path (U) of the insulation guide section (100), thereby inducing the flow of outside air to discharge heat from the rear of the module.

[0052] In addition, the opening frame (240) has a hollow portion formed inside to improve thermal insulation performance, and can be formed of a synthetic resin material (PVC, ABS, etc.) instead of metal to block thermal bridges.

[0053] Additionally, the horizontal member (50) may be provided with a horizontal body (51), a horizontal insulation material (52) provided inside the horizontal body (51), a horizontal fixing member (53) fixed to the horizontal insulation material (52) and exposed on one side of the horizontal body (51), a horizontal connecting member (54) fixed to the horizontal fixing member (53) and forming a space into which a PV module part (200) is inserted, and a horizontal finishing member (55) coupled to the horizontal connecting member (54) to finish the PV module part (200) and make the appearance beautiful.

[0054] Additionally, the vertical member (60) may be provided with a vertical body (61), a vertical insulation material (62) provided inside the vertical body (61), a vertical fixing member (63) fixed to the vertical insulation material (62) and exposed on one side of the vertical body (61), a vertical connecting member (64) fixed to the vertical fixing member (63) and forming a space into which a PV module part (200) is inserted, and a vertical finishing member (65) coupled to the vertical connecting member (64) to finish the PV module part (200) and make the appearance beautiful.

[0055] Next, the thermal insulation guide section (100) of a thermal insulation ventilation type BIPV system according to one embodiment of the present invention will be described in more detail.

[0057] FIG. 4 is a perspective view showing the overall appearance of the insulation guide section, and FIG. 5 is a cross-sectional view showing the cross-section of CC in FIG. 4 in detail.

[0058] Referring to FIGS. 4 and 5, the gap insulation material (120) may have a first gap surface (121) in contact with a horizontal member (50) and a vertical member (60), a second gap surface (122) in contact with a rear insulation material (110), and a third gap surface (123) in contact with a guide member (130) to block outside air attempting to pass through the gap between an auxiliary insulation body (232) and a fourth guide surface (134).

[0059] The first gap surface (121) is a surface where the gap insulation material (120) comes into direct contact with the horizontal member (50) and the vertical member (60), and can fill the gap between the building and the insulation material, block thermal bridges, and suppress the transfer of cold and hot air from the outside.

[0060] The second gap surface (122) allows the rear insulation material (110) and the gap insulation material (120) to form a continuous insulation layer, works integrally with the rear insulation material (110) to complement the insulation performance, and can prevent heat entering from the outside air from being directly transferred to the rear insulation material (110).

[0061] The third gap surface (123) is a surface that contacts the guide member (130), and blocks outside air from entering through the gap formed between the insulation frame (230) and the guide member (130). By doing so, the internal flow path (U) is formed only in the intended direction, and unnecessary inflow or leakage of outside air is prevented, thereby ensuring both insulation performance and ventilation efficiency.

[0062] Next, the guide member (130) may have a first guide surface (131) provided between the rear insulation material (110) and the PV module part (200), a second guide surface (132) that is bent backward from one end of the first guide surface (131) and contacts the rear insulation material (110), a third guide surface (133) that is bent forward from the other end of the first guide surface (131) and contacts one side of the gap insulation material (120), and a fourth guide surface (134) that is bent inward from the end of the third guide surface (133) and guides the outside air flowing in through the opening (S) into the internal flow path (U).

[0063] The first guide surface (131) is positioned between the rear insulation material (110) and the PV module section (200) to form the basic wall of the internal flow path (U), forms a path through which air introduced from the outside can flow, and can stably partition the air layer between the rear of the PV module section (200) and the insulation guide section (100).

[0064] The second guide surface (132) is formed by bending at one end of the first guide surface (131), contacts the rear insulation material (110), and can form a lateral boundary of the internal flow path (U) while firmly supporting the rear insulation material (110) and the guide member (130).

[0065] The third guide surface (133) is formed by bending at the other end of the first guide surface (131), contacts one side of the gap insulation material (120), and is combined with the gap insulation material (120) to form another lateral boundary of the internal flow path (U) and can block unnecessary external air inflow.

[0066] The fourth guide surface (134) is formed by being bent inward at the end of the third guide surface (133) and is in direct communication with the opening (S) to guide outside air into the internal flow path (U) so that it can be ventilated along the rear of the PV module part (200).

[0067] Through this, the thermal insulation guide (100) can block the thermal bridge phenomenon occurring between the horizontal member (50) and the vertical member (60) and the PV module (200), and form an internal flow path (U) to reduce the heat sensation of the PV panel (210) through the inflow of outside air.

[0068] In addition, the insulation guide section (100) can prevent damage to the insulation material caused by the outside air by forming an internal flow path (U) through the guide member (130).

[0069] In addition, the insulation guide section (100) can be formed as a single module with the rear insulation material (110), gap insulation material (120), and guide member (130) to facilitate construction.

[0070] Next, the PV module section (200) of the thermal insulation ventilation type BIPV system according to one embodiment of the present invention will be described in more detail.

[0072] FIG. 6 is a perspective view showing the overall appearance of the PV module section, and FIG. 7 is a cross-sectional view showing the cross-section of DD of FIG. 6 in detail.

[0073] Referring to FIGS. 6 and 7, the PV fixing bar (220) may be provided with a bar body (221) that is formed in a 'C' shape to wrap around both sides of the PV panel (210), a bar central projection (222) that protrudes from the center of the outer edge of the bar body (221) to fix an insulation frame (230) or an opening frame (240), and bar side projections (223) that protrude outwardly from each side of the bar central projection (222) to fix an insulation frame (230) or an opening frame (240).

[0074] Next, the insulation frame (230) may be provided with an insulation body (231) having a hollow portion formed inside, an auxiliary insulation body (232) provided on one side of the insulation body (231), a central clip (233) protruding from the upper and lower central portions of the auxiliary insulation body (232) and coupled with a bar central projection (222), and side clips (234) protruding from both upper and lower ends of the auxiliary insulation body (232) and coupled with bar side projections (223).

[0075] In addition, the insulation frame (230) can be formed from a synthetic resin material (PVC, ABS, polycarbonate, etc.) so that it can have a greater thermal bridge blocking effect compared to a metal frame.

[0076] The insulation body (231) is a basic frame bar that finishes both ends of the PV panel (210), is fixed to the horizontal member (50) and the vertical member (60), and has a hollow portion formed inside to lower the thermal conductivity and improve the insulation performance.

[0077] The auxiliary insulation body (232) is formed on one side of the insulation body (231) and has a separate compartment, which can supplement the insulation layer and increase structural strength.

[0078] The auxiliary insulation body (232) forms a hollow structure together with the insulation body (231) to provide an additional insulation effect and can also perform a supporting role for forming a clip.

[0079] The central clip (233) is a connecting part protruding from the central part of one side of the auxiliary insulation body (232), and is directly fastened to the bar central projection (222) of the PV fixing bar (220) to stably fix the perimeter of the PV panel (210), and since it is fastened at the central position, the load can be evenly distributed.

[0080] The central clip (233) can form a ‘T’ shape by having a projection protrude once more in each side direction from the central part.

[0081] The side clip (234) is a connecting part protruding from both ends of one side of the auxiliary insulation body (232) and is connected to the bar side projection (223) of the PV fixing bar (220) to prevent lateral shaking or deformation of the panel and to strengthen structural stability by dispersing the supporting force when external wind pressure or load is applied.

[0082] The side clip (234) can be formed in the shape of an 'L' for the protrusion.

[0083] Finally, the opening frame (240) may be provided with an opening body (241) having a hollow portion formed inside, a central clip (242) protruding from the upper and lower central portions of the opening body (241) and coupled with a bar central projection (222), and side clips (243) protruding from both upper and lower ends of the opening body (241) and coupled with bar side projections (223).

[0084] The opening frame (240) can also be formed from a synthetic resin material (PVC, ABS, polycarbonate, etc.), so the thermal bridge blocking effect can be greater than that of a metal frame.

[0085] The opening body (241) is a frame bar that finishes the upper and lower ends of the PV panel (210), and is connected to the insulation frame (230) to support the entire PV module part (200) in a square shape, and has a hollow part formed inside so that the insulation performance is improved and the thermal bridge phenomenon can be blocked.

[0086] Additionally, the opening body (241) is provided with an opening (S) that communicates with the internal flow path (U) of the insulation guide part (100), thereby performing a ventilation function by introducing and discharging outside air.

[0087] The central clip (242) is a connecting part that protrudes from the upper and lower central portions of the opening body (241), is fastened to the bar central projection (222) of the PV fixing bar (220), has the same shape and function as the central clip (242) of the insulation frame (230), and can provide fixing force to the upper and lower portions of the PV panel (210).

[0088] The side clip (243) is a connecting part protruding from each of the upper and lower ends of the opening body (241), and is fastened to the bar side projection (223) of the PV fixing bar (220). It fixes the left and right ends of the upper and lower parts of the PV panel (210) to prevent shaking or deformation, and together with the central clip (242), it distributes the supporting force when external wind pressure or load is applied, thereby strengthening structural stability.

[0089] Additionally, the central clip (242) and the side clip (243) may have the same shape as the central clip (233) and the side clip (234) of the insulation frame (230).

[0090] Through this, the thermal insulation ventilation type BIPV system according to one embodiment of the present invention can secure thermal insulation performance at the level of a multi-layer module by having the thermal insulation guide part (100) and the PV module part (200) work together.

[0091] In addition, the thermal ventilation type BIPV system allows outside air to be introduced through a guide member (130) forming an internal air passage (U), thereby effectively discharging heat from the rear of the PV panel (210), thus preventing heat burning and maintaining stable power generation efficiency.

[0092] In addition, the insulation frame (230) and the opening frame (240) are formed of synthetic resin material, which has a greater thermal bridge blocking effect compared to a metal frame and prevents the insulation guide part (100) from falling off, thereby increasing structural stability and simultaneously improving power generation efficiency, insulation performance, ventilation performance, and economic efficiency.
