Problems solved by technology

When the photovoltaic curtain wall absorbs sunlight to generate electricity, the temperature of the building facade will still rise due to the heat generated by the backplane of the photovoltaic panel, resulting in an increase in the indoor temperature of the building and an increase in the air conditioning load in summer

Embodiment 1

[0033] A photovoltaic building facade, such as Figure 1 to Figure 3 As shown, a photovoltaic building facade includes a building exterior wall 1 and a photovoltaic panel 2 arranged on the outside of the building exterior wall 1. A water flow channel 9 and an air flow channel 8 are arranged between the photovoltaic panel 2 and the building exterior wall 1, and the water flow The channel 9 is connected to the hot water supply circuit of the photovoltaic building; the heat generated by the photovoltaic panel 2 is conducted to the water in the water channel 9 through the air in the air channel 8, thereby providing hot water for the photovoltaic building. Wherein the type of the building exterior wall 1 can be a maintenance wall and a load-bearing wall.

[0034] The water channel 9 is arranged on the surface of the building exterior wall 1 and exchanges heat with the photovoltaic panel 2 through the air in the air channel 8 . Specifically, it can also be embedded in the surface o...

Embodiment 2

[0040] The similarities between this embodiment and the first embodiment will not be described, only the differences will be described.

[0041] The significant difference between the present embodiment and the present embodiment is that in the present embodiment, the water channel 9 is connected with the photovoltaic panel 2 to form a photovoltaic curtain wall, and the photovoltaic curtain wall is fixed on the building exterior wall 1 through a connecting component. The connection components generally include the sub-frame system for laying out the photovoltaic curtain wall, such as aluminum alloy hanging seat horizontal profiles 5, vertical aluminum alloy profiles 6, bolts 4, corner brackets, and related components such as embedded parts in the building exterior wall 1.

[0042] More preferably, the water flow channel 9 can be embedded in the air flow channel 8 to increase the heat exchange efficiency.

[0043] The method of integrating photovoltaic panels 2, water flow chan...

Abstract

The invention relates to a photovoltaic building vertical surface and a photovoltaic curtain wall. The photovoltaic building vertical surface comprises a building exterior wall and photovoltaic panels arranged on the outer side of the building exterior wall, wherein a water flow channel and an air flow channel are formed between the photovoltaic panels and the building exterior wall; the water flow channel is connected with a hot water supply loop of a photovoltaic building; and heat energy generated by the photovoltaic panels is guided into water in the water flow channel through air in the air flow channel so as to provide hot water for the photovoltaic building. The photovoltaic curtain wall comprises photovoltaic panels and a water flow channel, the water flow channel is arranged on one sides of the photovoltaic panels, and an air flow channel for air to circulate is formed between the water flow channel and the photovoltaic panels. Compared with the prior art, the photovoltaic building vertical surface and the photovoltaic curtain wall have the advantages that an air circulation cooling method and a water circulation cooling method are integrated so that the temperature raising effect of the photovoltaic panels can be well controlled, the heat energy generated by back plates of the photovoltaic panels is used for heating water so as to provide hot water for the photovoltaic building, and energy consumption of hot water required for life and production can be reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic building facades, in particular to a photovoltaic building facade and a photovoltaic curtain wall. 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 from bottom to top Arrang...
