Abstract

The photovoltaic passive heating wall consists of: glass panels with photovoltaic cells glued to the back, two winter ventilation openings, two summer ventilation openings, a heat collecting wall, a DC fan for accelerating the air flow in the air flow channel, photovoltaic glass panels installed in parallel On the frame of the heat collecting wall, two winter vents are opened on the upper and lower parts of the heat collecting wall, two summer vents are opened on the upper and lower parts of the air flow channel, and the DC fan is installed in the winter vent or the air flow channel. The invention has a photovoltaic cell on the back of the glass plate of the traditional passive heating wall system, and the heat on the surface of the photovoltaic cell is taken away by the air flow in the air flow channel between the glass plate and the wall, thereby reducing the temperature of the battery and improving the power generation efficiency of the battery , not only has the function of power generation and heating, but also makes the appearance of the building more attractive.

Description

technical field [0001] The invention relates to a building integrated photovoltaic photothermal (BIPV / T) device for a passive solar house, belonging to the field of solar energy utilization. Background technique [0002] The limitation of conventional energy resources and the increase of environmental pressure have made many countries in the world re-strengthen their support for the development of new energy and renewable energy technologies. Solar energy is a clean, efficient and inexhaustible new energy source, so the governments of all countries regard the utilization of solar energy resources as an important content of the national sustainable development strategy. Among the existing solar energy utilization technologies, passive solar heating technology, solar hot water utilization technology and photovoltaic power generation technology are mostly adopted. Among them, the passive heating wall (Trombe wall) in the passive solar heating technology has the advantages of s...
