Description

Technology Field

[0001] The present invention relates to an integrated system of solar power generation tiles for a building wall, and more specifically, to an integrated system of solar power generation tiles for a building wall that enables the expansion of the installation surface area and the constant maintenance of solar power generation efficiency without environmental constraints by applying panel-shaped tiles having a solar power generation function to the exterior wall of a building. Background Technology

[0003] Environmental issues caused by global warming are receiving steady global attention, and eco-friendly and sustainable new and renewable energy is gaining interest to reduce greenhouse gas emissions from fossil fuel use and to address the depletion of fossil fuel resources.

[0005] Accordingly, the government is promoting the expansion of renewable energy with the goal of supplying 20% ​​of electricity generation from renewable energy by 2030, and the supply of solar power generation at the apartment complex level is also actively taking place through the Korea Energy Agency and local governments via housing supply support projects and small-scale solar power installation support projects.

[0007] Among renewable energies, solar power generation systems are a method of generating electricity by converting sunlight into direct current. Solar power generation utilizes solar panels composed of multiple solar cells. As the demand for renewable energy increases, the production of solar cells and solar arrays is also on the rise. As such, solar power generation systems have the advantage of being able to generate electricity using an infinite energy source and help solve environmental pollution problems.

[0009] Recently, there has been growing interest in building photovoltaic systems, which apply solar power generation systems to buildings and use the generated electricity directly within the building.

[0011] However, there are limitations on the locations for installing solar panels when constructing building-mounted photovoltaic systems, and the use of solar power facilities may be restricted due to reasons such as insufficient installation space and aesthetic issues.

[0013] As prior art disclosed to solve the above-mentioned problems, Korean Published Patent Application No. 8860 (January 21, 2022) describes a solar energy roof tile having a shape substantially corresponding to the shape of a conventional tile and capable of being thermally and / or electrically connected to an adjacent solar energy roof tile. The tile comprises a lower surface disposed in at least a portion of a roof structure, an upper surface opposite to the lower surface (the upper surface is formed in at least a portion of a portion by a solar energy utilization module), two opposing side walls, a rear surface connecting the two side walls, and a front surface opposite to the rear surface also connecting the two side walls. The two side walls, the rear surface, and the front surface together connect the lower surface and the upper surface, thereby forming a cavity between the two side walls, the rear surface, the front surface, the lower surface, and the upper surface. The lower surface has a lower opening providing access in the area of ​​the front surface, and the upper surface is configured to provide access from the periphery to the cavity in the area of ​​the rear surface, so that production, installation, and maintenance are simple. Solar energy roof tiles with an upper opening that can provide an affordable product are known.

[0015] However, the aforementioned conventional technology is installed restrictively only on the roofs of buildings, which limits the installation surface area of ​​roof tiles for solar energy generation. Furthermore, there is a problem in that the installation surface area is extremely restricted due to the load-bearing capacity of the roof structure. This resulted in a decrease in solar power generation efficiency while compromising installation safety.

[0017] In addition, conventionally, there were problems such as being vulnerable to environmental influences that hinder solar power generation, such as snow accumulating on the roofs of buildings, a short construction life cycle (approximately 10 years) following reduced product durability, and significantly reduced power generation efficiency in low sunlight at the beginning or end of the year. Prior art literature

[0018] KR Published Patent Application No. 10-2022-0008860 (January 21, 2022) The problem to be solved

[0019] The present invention aims to solve the aforementioned problems by providing an integrated system of solar power generation tiles for a building wall that simplifies installation, enhances construction durability, expands the installation surface area capable of generating solar power, and maximizes solar power generation efficiency, by applying solar power generation panel-type tiles to the exterior wall finish of a building and configuring them to be installed continuously in a sliding manner. means of solving the problem

[0021] The integrated system of a building wall for a photovoltaic power generation tile proposed by the present invention comprises: a module frame installed in correspondence with the exterior wall of a building; an insulating member installed inside the module frame to block temperature changes and heat loss of the exterior wall of the building; a PV tile section installed on the module frame to finish the exterior wall and to generate electrical energy by receiving sunlight; and a tilting guide bar installed inside the module frame in correspondence with the bottom of the PV tile section and contact-supporting the light-receiving surface of the PV tile section so that it tilts upward.

[0023] The above module frame comprises a metal frame installed in correspondence with the outer wall surface of a building and an insulation block section that surrounds the metal frame and forms an inner and outer insulation layer.

[0025] In the above module frame, a tile installation groove is formed at one end that is inwardly concave to support the PV tile portion.

[0027] In addition, the integrated system of a building wall for solar power generation tiles proposed by the present invention may further comprise a guide rail that is installed to be spaced apart on the exterior wall of a building and forms a guide path in a straight longitudinal direction extending left and right, and a guide module that is installed on the module frame and configured to slide along the guide path of the guide rail. Effects of the invention

[0029] According to the integrated system of a building wall for solar power generation tiles of the present invention, since solar power generation panel-type tiles are configured to be used as exterior wall finishes of a building, the installation surface area for solar power generation of the building is expanded to improve the installation limitations of the building's limited roof surface area, thereby enhancing solar power generation efficiency. Furthermore, by being free from environmental interference effects on solar power generation, the effect of maximizing solar power generation while maintaining excellent durability and power generation efficiency at all times is obtained.

[0031] In addition, the integrated system of the solar power generation tile on the building wall according to the present invention is configured to be continuously installed on the exterior wall of a building in a sliding manner, so the construction structure is simple, which has the effect of improving constructability and shortening the construction period.

Specific details for implementing the invention

[0034] The present invention features an integrated system of a building wall for solar power generation tiles, comprising: a module frame installed in correspondence with the exterior wall of a building; an insulating member installed inside the module frame to block temperature changes and heat loss of the exterior wall of the building; a PV tile section installed on the module frame to finish the exterior wall and to generate electrical energy by receiving sunlight; and a tilting guide bar installed inside the module frame in correspondence with the bottom of the PV tile section and to contact and support the light-receiving surface of the PV tile section so that it tilts upward.

[0036] Next, a preferred embodiment of an integrated system of a building wall with photovoltaic tiles according to the present invention will be described in detail with reference to the drawings.

[0038] First, an embodiment of the integrated system of a building wall for solar power generation tiles according to the present invention comprises, as shown in FIGS. 1 and 2, a module frame (10), an insulating member (20), a PV tile section (30), and a tilting guide bar (40).

[0040] The above module frame (10) is configured to be installed in correspondence with the outer wall of the building.

[0042] The above module frame (10) supports the main components of the present invention (e.g., an insulating member (20), a PV tile section (30), a tilting guide bar (40), etc.). Furthermore, the above module frame (10) performs the function of enhancing thermal insulation performance while preventing the spread of fire in the building between a plurality of the above PV tile sections (30).

[0044] As shown in FIG. 3, the above module frame (10) comprises a metal frame (11) installed in correspondence with the outer wall surface of a building and an insulation block part (13) that surrounds the metal frame (11) and forms an inner and outer insulation layer.

[0046] The above metal frame (11) is basically constructed using a metal material that is durable and withstands high temperatures well.

[0048] The insulation block section (13) forms an insulation layer that is separated into inner and outer layers. That is, the insulation block section (13) is formed to have a foam-shaped insulation layer that directly wraps the metal frame (11) on the inside, and a thin and light vacuum insulation material-shaped insulation layer on the outside that has excellent insulation performance.

[0050] The above module frame (10) has a tile installation groove (15) formed at one end that is inwardly concave to support the PV tile portion (30).

[0052] The tile installation groove (15) is formed to be fitted and coupled in correspondence with the inclined installation angle of the PV tile section (30). At this time, the tile installation groove (15) is formed to extend in the longitudinal direction of the module frame (10) to guide contact so that the PV tile section (30) can be coupled in a continuous sliding manner.

[0054] As shown in FIG. 2, the above-mentioned insulating member (20) is installed inside the module frame (10) and is configured to perform the function of stably maintaining the indoor temperature of the building by blocking basic temperature changes and heat loss of the building's exterior wall.

[0056] The above-mentioned insulating member (20) is applied in the form of a sheet on the inner side of the module frame (10), and the materials applicable to the insulating member (20) are composed of materials with low thermal conductivity and excellent insulating performance, such as expanded polystyrene, extruded polystyrene, glass fiber, mineral wool, and foam board.

[0058] As shown in FIGS. 1 and 2, the above PV tile section (30) is configured as a plate-shaped structure that replaces the exterior wall tiles of a building and is installed on the module frame (10) to finish the exterior wall.

[0060] The above PV tile section (30) is configured to generate electrical energy by receiving sunlight, and comprises an outer frame (31) and a solar cell module (33).

[0062] The outer frame (31) mounts and fixes the solar cell module (33) by contacting it along the outer edge of the solar cell module (33). At this time, the outer frame (31) is configured to connect power lines necessary for solar power generation in the PV tile section (30) from the inside, thereby preventing the exposure of electrical connection configurations such as cables.

[0064] The outer frame (31) is configured to slide in contact with the tile installation groove (15) of the module frame (10) so as to install and fix the PV tile part (30) on the module frame (10).

[0066] The above solar cell module (33) is configured to generate electrical energy by directly receiving sunlight, and is equipped with a plurality of PV cells (33a) capable of receiving sunlight, and is configured with a PV film (33b) that surrounds and protects the front of the PV cells (33a).

[0068] In the above, since the PV film (33b) is constructed using an ultra-lightweight film on a crystalline PV, it is possible to reduce the weight to 1 / 5 of that of a conventional PV module while minimizing the load burden on the building.

[0070] In addition, the above PV film (33b) can also be configured by applying crystalline PV translucent color printing. That is, the solar cell module (33) of the above PV tile section (30) can selectively apply various colors such as white, gray, green, blue, and orange to improve the aesthetic appeal of the building's exterior wall.

[0072] The tilting guide bar (40) performs the function of guiding the installation of the PV tile section (30) at a constant angle of inclination while contacting and supporting the tilted installation state of the PV tile section (30) on the module frame (10).

[0074] The above tilting guide bar (40) has a circular cross-sectional shape and extends in the left and right lateral directions, and is configured to be installed within the module frame (10) corresponding to the bottom of the PV tile section (30).

[0076] The tilting guide bar (40) contacts and supports the PV tile section (30) so that the outer wall surface, i.e., the light receiving surface, of the PV tile section (30) is tilted upward. At this time, the upward tilt of the PV tile section (30) is configured to form an angle of inclination (α) of 1 to 2˚ relative to a virtual vertical wall.

[0078] In other words, according to the integrated system of a building wall for solar power generation tiles of the present invention configured as described above, since solar power generation panel-type tiles are configured to be used as exterior wall finishes of a building, it is possible to improve the installation limitations of the building's limited roof surface area and expand the installation surface area for solar power generation, thereby enhancing solar power generation efficiency, as well as maximizing solar power generation while maintaining excellent durability and efficiency at all times, by being free from environmental interference effects on solar power generation.

[0080] And another embodiment of the integrated system of a building wall of a solar power generation tile according to the present invention is a combined structure that can be slidably installed on the outer wall of a building as shown in FIG. 4, and further comprises a guide rail (50) and a guide module (55).

[0082] The above guide rails (50) are configured to be installed on the outer wall of a building with a number of them spaced apart from each other.

[0084] A guide path (51) is formed in the guide rail (50) along a straight longitudinal direction extending left and right. That is, the module frame (10) is installed by binding it onto the guide path (51), and it is possible to install a plurality of module frames (10) continuously along the longitudinal direction of the guide path (51).

[0086] The guide module (55) is installed on the rear side of the module frame (10), that is, on the side facing the building, and is configured so that the guide module (55) can slide along the guide path (51) of the guide rail (50).

[0088] When the present invention is configured as in the other embodiments described above, it is configured to be continuously installed on the exterior wall of a building in a sliding manner, so the construction structure is simple, making it possible to improve constructability and shorten the construction period.

[0090] In the other embodiments described above, since it is possible to implement them with the same configuration as the first embodiment described above, except for the configuration described above, a detailed description is omitted.

[0092] Although a preferred embodiment of the integrated system of a building wall with photovoltaic tiles according to the present invention has been described above, the present invention is not limited thereto and can be implemented with various modifications within the scope of the claims, the specification of the invention, and the attached drawings, and such modifications also fall within the scope of the present invention.
