BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall system to which a solar cell module is applied. A solar cell module (PV Module; Photovoltaic) which produces electric energy in place of a common glass plate on a wall that does not bear a load of a building, that is, a non-bearing wall. It is related with solar panel (PV) module curtain wall system which integrates a module and has the convenience of constructability and repair, and it also has a solar cell in a spandrel part (interlayer part of a building) which does not obstruct the view from the room. It is applied to the curtain wall system to which the solar cell module is applied to satisfy the external beauty and stability of the components by applying the module and treating the junction box and wiring, which are components of the PV module, to be not exposed to the outside. It is about.

In general, building integrated photovoltaic power generation, BIPV (Building Integrated Photovoltaics) among PV systems, is applied to building envelopes by building solar cell modules into building envelopes to increase PV efficiency and various added values to more efficiently distribute PV systems. The concept to activate. The BIPV system offers the possibility of providing another function in combination with the building envelope at the same time as the production of electrical energy. In addition, there is no need for a separate site acquisition cost for the PV system and the cost of constructing the structure to support the PV system, and it has the advantage of generating electricity at the point where the electric load is generated.

The conventional domestic BIPV system has a flat roof type with solar modules installed on the roof of a building, a slope roof type with solar modules installed on a slope roof of a typical house, and an additional slope on the wall of the building. The sunshade type using solar cell modules is the main structure. This type of BIPV system has a disadvantage in that a separate structure must be installed, and in reality, it is inadequate to be applied to the buildings of modern society that are becoming taller. However, when the solar cell module is applied to the curtain wall, it is not necessary to install such an additional structure, and it is advantageous that the solar cell module can be sufficiently installed by replacing the plate glass with building materials.

In Korea, there are few cases where the solar cell module is actually applied to the curtain wall, and the case where the solar cell module is recently applied to the curtain wall system (practical practical publication 20-0420311) can be found. In general, in the case of mullions in the frame of the curtain wall, the length of one layer (up to 4 ~ 5m) is installed, and the external mullion cap and the screw-fixed mullion clamp It is also mounted to the same length as the mullion frame to secure the pane. However, in the case of the previous case, it is not easy to repair, and in the case that one or more solar cell modules need to be replaced in the future, in order to repair the actual solar module, an external mullion cap and a screw corresponding to one layer are required. The mullion clamps must be separated from each other, which is difficult to repair. In addition, since the mullion cap has to be removed by applying physical force, it is difficult to generate scratches and it is difficult to preserve the original shape, so that most of them cannot be remounted, and the cost of the new frame must be utilized. In this case, in order to process the electric wire from the solar cell module, it is necessary to follow the processing of several holes on the main frame (mulion and transom) of the curtain wall, which adversely affects the airtightness, watertightness, and insulation properties required for the curtain wall. The disadvantage is that it can have.

The present invention not only solves the problems of the prior art but also proposes a new curtain wall application method of the solar cell module, integrating the solar cell module for producing electrical energy in place of the common plate glass to the curtain wall of the building component Therefore, the purpose is to secure energy supply and demand through construction of the building's own power and auxiliary power through the shell of the building, as well as to provide convenience in construction and repair.

In addition, the present invention is applied to the solar cell module in the Spandrel portion (interlayer part of the building) that does not obstruct the view from the room, the junction box and wiring which is a component of the solar cell module to the outside The purpose is to satisfy the apparent beauty and stability of the components by treating them without exposure.

A circular rubber bushing 212 for protecting the wire 103 and the connector 104 connected to the connection wiring box 102 is configured.

In addition, the pipe grooves 307a are formed at upper ends of both sides of the back panel 307 disposed inside the solar cell module panel 200 so that the solar cell module panel 200 can be wired from the indoor side. In addition, the saddle 312 is fixed to the outside of the pipe groove 307a, and the PVC pipe 309 is fixed to the inside of the saddle 312 to secure an electric wire passage.

In more detail, when the solar cell module of double-layered glass and G / G (Glass to Glass) type is installed as a solar cell module panel in a general curtain wall system that can form the outer wall of a building, it provides ease of construction. At the same time it has the convenience of maintenance and repair of the solar cell module.

Applied.

25% of total energy costs in Korea are used in buildings, and about one-third of them are in windows and curtain walls.In curtain wall systems, condensation and phenomena that can be caused by indoor and outdoor temperature differences In consideration of energy loss, it is essential to secure insulation performance on the outer wall directly facing the outside air. Therefore, the aluminum module frame 210 by using a polyurethane insulation system 211 to configure the insulation space and to block the thermal bridge, to minimize the heat loss through the aluminum frame to improve the insulation performance indoor and outdoor It prevents dew condensation and reduces the high sound transmission effect of metals, improving sound insulation performance.

The connection wiring box 102 installed at the upper end of the solar cell module is hidden inside the frame and is hidden from view from the outside, and is protected by the aluminum frame. On the other hand, in order to pass the wire 103 and the connector 104 coming out of the connection wiring box 102 to the outside of the frame, a hole is drilled in the upper frame. When the glazing of the solar cell module and the actual building installation work, the wire 103 and the connector 104 may be damaged by the frame, and in extreme situations may result in electrical leakage. In order to protect against these, the wiring hole 210d is finished using a rubber bushing 212 having the form of FIG. 4.

When a G / G type module is applied as shown in FIG. 3A, an adapter frame 215 is first inserted into the module frame, cut and assembled at an angle of 45 degrees, and then the glazing gasket 214a is fitted.

In addition, when the multilayer glass type module is applied as shown in FIG. 3b, when the module frame 210 cut at 45 degrees is assembled to all four surfaces, the glazing gasket 214a is first mounted to mount the solar cell module on the module frame. The solar cell module is mounted on the glazing gasket 214a and at the same time, the wire processing for removing the wire 103 and the connector 104 to the outside is performed.

When the solar cell module is installed and the wire processing is completed, the glazing bead 213 cut at 90 degrees is fitted to the four sides of the module frame 210 to secure the airtight performance and closely adhere to the solar cell module. By inserting the glazing gasket 214b for this, the solar cell module panel is completed as shown in FIG. 5.

Application of the solar cell module panel is made as in the vertical section of the curtain wall of Figure 6, which is a cross-sectional view of A-A 'of FIG. The aluminum curtain wall in this figure is transom [Transom; In the horizontal cross-sectional view, a mullion] 301, a clamp 302, a cap 303, and the like are formed, and the clamp 302 is fixed by a screw 313. In addition, the insulation performance is reinforced by the application of the polyamide insulation system 304. Generally, a back panel 307 filled with a heat insulating material 306 such as glass wool or polyester is mounted on a steel plate 305 in the spandrel portion. The back panel 307 was also applied to a curtain wall system for a solar cell module.

In general, after the back panel 307 is mounted, the interior is finished with silicon 308. When the solar cell module panel is applied, an electric wire passage is required to allow wiring work indoors. Done. In the present invention by manufacturing a predetermined space that can enter the PVC pipe in the two upper edges of the back panel 307 as shown in Figure 7 by installing a fixed cut and fixed PVC pipe 309 in the saddle (312) Wire passages can be secured and the caulking finish around the PVC pipe is silicone. Mounting of the solar cell module panel first pulls out the electric wire 103 and the connector 104 to the indoor side through the already secured wire passage, the solar cell module in the state before the clamp 302 and the cap 303 is mounted The panel is mounted on the mullion and the transom 301 on which the gasket 310 is mounted and fixed by the clamp 302 to cover the cap 303. The space formed between the solar cell module panel and the cap may be finished with silicon 311 to complete the mounting of the solar cell module panel.

When the mounting of the solar cell module panel is completed, the connection process of the wire 103 and the connector 104 of the module should be accompanied. FIG. 8 is a horizontal cross-sectional view of the curtain wall to which the solar cell module panel is applied, and is a cross-sectional view of B-B 'of FIG. 1. This shows the wiring relationship between the solar cell module, the connection of all the wires 103 and the connector 104 is made in the room. The two wires 103 (+) and (-) connected to the top of each solar cell module and the connector 104 respectively have opposite poles coming from the opposite PVC pipe 309 adjacent to the mullion 301. It may be connected to the wire 103 and the connector 104 corresponding to + or-). For example, the (+) line coming from the solar cell module installed on the left side is connected to the (-) line coming out of the solar cell module installed on the right side ((+) line if the electrode of the left module is (-)). In this way, solar cell modules corresponding to one floor of a building can be connected to each other to produce electrical energy.

 It is reported that the general lifespan of the solar cell module currently being used is from 15 to 20 years. This means that as time goes on, the solar cell module ages, and when the module reaches the end of its life, it must be replaced with a new solar cell module. In addition, when it is applied to buildings, it is exposed to the outside, so even if the solar cell module is damaged by the surrounding environment such as natural disaster or artificial damage, replacement is necessary for continuous electric energy generation. In order to replace the solar cell module in the present invention, first, in the room, the wires of the solar cell module to be replaced can be separated from the adjacent module, and then the solar cell module can be easily repaired through the process of FIG.

First, the glazing gasket 214b, which is fitted on four sides from the outside, is formed from the glazing bead 213 and the solar cell module. Then, the glazing beads 213 rotated and inserted into the four sides of the module frame 210 are pressed to the solar cell module surface and separated from the module frame. In this case, a space for removing the solar cell module is secured, and the solar cell module can be easily separated by removing the setting block 216 that was supporting the solar cell module at the bottom and pulling the solar cell module to be replaced. Let's go. At this time, the wire 103 and the connector 104 which are previously separated in the room are moved and separated smoothly to the outdoor side along the wiring path made of the PVC pipe 309. On the other hand, the arrow direction indicated by B in the drawing is a process of mounting a new solar cell module on an aluminum frame, and has the feature of easily remounting the solar cell module by proceeding in the reverse order of A process.

As described above, the present invention integrates a photovoltaic module (PV module) that produces electric energy in place of a general plate glass on a wall that does not bear a load of a building, that is, a non-bearing wall. It has the advantage and effect of providing the curtain wall system with the convenience of constructability and repair as well as securing the energy supply and demand through the production of the building itself and auxiliary power through the envelope.

In addition, the curtain wall, which is the outer shell of the building, can be applied not only as an electric energy production tool but also to the buildings of modern society that are getting higher, and solve the difficulties of construction and repair of the existing solar cell module and insufficient processing of wires. Can be. In addition, the solar cell module can be easily applied to the Spandrel part (interlayer part of the building), which does not obstruct the view from the room, and the junction box and the wires, which are components of the solar cell module, to the outside By not exposing the treatment, it is possible to expect the effect of satisfying the stability of the component as well as the appearance beauty.
