Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0023] A reflective and heat-insulated photovoltaic building facade, such as figure 1 and figure 2 As shown, it includes a building exterior wall 1 and a photovoltaic panel 2 located on the outside of the building exterior wall 1. The exterior surface of the building exterior wall 1 is provided with a heat reflective layer 3, and there is a space between the photovoltaic panel 2 and the building exterior wall 1 for air circulation. The air channel 8. Specifically, the photovoltaic panel 2 can be installed on the facade of the building through the sub-frame. like figure 1 As shown...

Abstract

The invention relates to a reflection heat insulation type photovoltaic building elevation and a photovoltaic building. The reflection heat insulation type photovoltaic building elevation includes a building exterior wall and a photovoltaic panel arranged at the outer side of the building exterior wall; the surface of the outer side of the building exterior wall is provided with a heat reflection layer; and an air flow channel for air circulation exists between the photovoltaic panel and the building exterior wall. The photovoltaic building is a building at least one surface of which adopts the reflection heat insulation type photovoltaic building elevation. Compared with the prior art, the reflection heat insulation type photovoltaic building elevation of the invention is provided with the heat reflection layer which can reflect heat emitted by the back panel of the photovoltaic panel, and therefore, indoor temperature rise of the building caused by heat emission of the back panel of the photovoltaic panel can be alleviated, and the reflection heat insulation type photovoltaic building elevation is provided with the air flow channel which makes reflected heat taken away from the surface of the wall through air.

Description

technical field [0001] The invention relates to the field of photovoltaic building facades, in particular to a reflective heat-insulating photovoltaic building facade and a photovoltaic building. Background technique [0002] Photovoltaic building is a multi-functional building form developed in recent years that uses solar power to power buildings. Combining photovoltaic panels with buildings, especially high-rise buildings, and using the huge facade area of ​​high-rise buildings to absorb solar energy to provide power for buildings to alleviate the problem of electricity shortage in cities, especially large and medium-sized cities, is a current development direction with broad prospects. [0003] For example, Chinese patent CN102587545A discloses a photovoltaic building glass curtain wall assembly, including solar cells, glass substrates, glass backplanes, battery interlayers, glass substrates, battery interlayers, solar cells, battery interlayers, and glass backplanes fro...
