Composite photo voltaic hot water building integrated member and its producing process

Abstract

The present invention is composite photovoltaic water heating integrated building member and its production process. The composite photovoltaic water heating integrated building member includes photovoltaic assembly, heat collector, heat insulating layer and back plate laminated and fixed aluminum alloy frame. The production process includes the following steps: smearing polyethylene-vinyl acetate to photovoltaic cell, setting the photovoltaic cell between two layers of composite fluoric plastic film and pressing in a vacuum press to form; smearing silica gel to the heat absorbing surface of the heat collector and adhering the photovoltaic cell assembly; covering the other surface of the heat collector with heat insulating layer and back plate, fixing with frame and covering with glass plate. The integral member may be combined with wall or roof to produce electricity and hot water simultaneously in high efficiency.

Description

Technical field [0001] The invention relates to a solar photovoltaic building integrated component and its manufacturing process, in particular to a composite photovoltaic hot water building integrated (BIPV / T) component, which belongs to the field of solar energy utilization. Background technique [0002] Among the many renewable energy sources, solar power generation has the most technological content and development prospects, and the BIPV system is considered the preferred photovoltaic (PV) power generation system (Europe’s 2010 PV development target). The solar roof of UNI-SOLAR in the United States directly generates amorphous thin film batteries on thin steel sheets. The steel sheets can be cut arbitrarily to achieve the width of the roof; the amorphous solar glass curtain wall of RWE Company in Germany has realized the gap between the solar cells. "Wireless connections. The above two structures only pay attention to the cooling of the battery, and do not use the cooling m...

AI Technical Summary

Problems solved by technology

However, the above techniques have certain limitations

Firstly, the photovoltaic module and the solar hot water collector or air collector are independent of each other; secondly, the photovoltaic cell is directly installed on the roof or the glass surface, and only the air cools the photovoltaic cell, which is not sufficient for the cooling effect of the battery. The power generation efficiency will decrease linearly with the increase of the working temperature; again, the photovoltaic system and the solar water heating system are independent of each other, but the area that can be used on the roof is limited, especially for high-rise buildings in cities, which will hinder the photovoltaic system and the solar thermal system. At the same time, the large area of ​​the south wall is not fully utilized
