Photo-thermal collection type energy-saving building curtain wall

Abstract

The invention discloses a photo-thermal collection type energy-saving building curtain wall. The photo-thermal collection type energy-saving building curtain wall comprises a hollow keel support fixedly installed outside the outer wall face of a building, wherein one or more installation cavities are formed in the hollow keel support at equal intervals; the outer side ends of the bottom faces of the installation cavities are each provided with a groove; an elastic connecting piece is installed in each groove; the other end of each elastic connecting piece is connected with a sealing framework;the outer side face of each sealing framework is a glass curtain wall plate; and the inner side face of each sealing framework is a photovoltaic power generation plate. The installation cavities aresealed through the whole sealing frameworks. According to the building curtain wall structure, the installation cavities are sealed at night and used for outer wall heat preservation, the sealing frameworks can be opened in the daytime to expose the photovoltaic power generation plates so that a light inlet cavity can be exposed, external light can penetrate through the light inlet cavity to entera room, and the luminous flux is increased; and meanwhile, the power generation rate is increased and the light incidence amount is increased through a reflective film layer, and the indoor brightness is higher in the daytime.

Description

technical field [0001] The invention relates to a building curtain wall, in particular to a light and heat collection type energy-saving building curtain wall. Background technique [0002] Building curtain wall is a commonly used exterior wall decoration at present. It is not used as a load-bearing exterior wall. Due to the large surface area of ​​the building curtain wall after laying, many people tend to design the building curtain wall as a photovoltaic curtain wall. However, due to the installation of photovoltaic curtain walls, resulting in The illuminance in the interior of the building is insufficient, so that the external light cannot enter the room through the curtain wall, resulting in insufficient indoor light during the day and a dim situation. At present, some photovoltaic curtain wall panels that can be pulled by hand can be opened to meet the light injection. However, because the opening method is based on motors, etc., the use cost increases, the purchase co...

[0002] Building curtain wall is a commonly used exterior wall decoration at present. It is not used as a load-bearing exterior wall. Due to the large surface area of ​​the building curtain wall after laying, many people tend to design the building curtain wall as a photovoltaic curtain wall. However, due to the installation of photovoltaic curtain walls, resulting in The indoor illuminance of the building is insufficient, so that the external light cannot enter the room through the curtain wall, resulting in insufficient indoor light during the day and a dim situation. At present, some photovoltaic curtain wall panels that can be pulled by hand can be opened to meet the light injection. However, because the opening method is based on motors, etc., the use cost increases, the purchase cost increases, and it is easy to be damaged, and the opened photovoltaic curtain wall panels are not fully opened due to the included angle of travel, so the luminous flux is actually not very good
