Technical Field

[0001] The invention relates to the technical field of building curtain walls, and in particular to a photovoltaic sunshade system for curtain walls. Background Art

[0002] The curtain wall is the exterior wall enclosure structure of a building. It is hung on the main structure like a curtain, so it is also called a suspended wall. It mainly includes panels and supporting structure systems. Since most curtain wall panels are made of glass, solar radiation will be transmitted into the room through the curtain wall in large quantities, causing heat accumulation and increasing the indoor cooling load. In addition, long-term exposure to the sun will accelerate the aging of the curtain wall materials. For example, the glass may suffer from thermal stress cracking, and the metal frame will deform and oxidize due to thermal expansion and contraction.

[0003] In order to reduce the heat transfer into the room, improve the energy-saving effect of the building, and extend the service life of the curtain wall, corresponding sunshade structures are usually set up, such as sunshades, curtains, etc.; however, the traditional building sunshade decorative strip molding system is usually implemented in a single form such as aluminum alloy wire or laminated glass or aluminum plate packaging. Compared with the current development trends of green buildings and low-carbon buildings in the construction industry, only considering building sunshade can no longer fully meet the functional needs of the building itself.

[0004] Therefore, in view of the characteristics of curtain walls of buildings such as low-carbon and green three-star buildings, solar energy is used as the main energy source to achieve low-carbon buildings. Taking into account the curtain wall building shape with its own shading and the application of solar energy, we proposed a photovoltaic shading system for curtain walls. Summary of the invention
