Photovoltaic, photo-thermal and lighting energy comprehensive utilization device

Abstract

The invention relates to a photovoltaic, photo-thermal and lighting energy utilization device. The device comprises a transparent light concentration prism cover plate, anti-reflective films, photovoltaic cells, side plates, a bottom plate, a ventilation pipe and a fan. The surface of one side of the transparent light concentration prism cover plate is a plane, and solid light concentration prisms in parallel are evenly distributed on the surface of the other side of the transparent light concentration prism cover plate. The two side faces of each solid light concentration prism are symmetrical parabolic faces. The photovoltaic cells are pasted at the bottoms of the solid light concentration prisms. The anti-reflective films are located between the solar photovoltaic cells and the lower bottom surfaces of the solid light concentration prisms. The bottom plate and the side plates are transparent, and small holes are evenly machined in the bottom plate. The side face of the transparent light concentration prism cover plate and the side plates are connected to form a closed-loop enclosed space. One face, provided with the solid light concentration prisms, of the transparent light concentration cover plate is located in the enclosed space. The enclosed space is sealed by the bottom plate, the side plates are connected to the ventilation pipe to be communicated with the enclosed space, and the exhaust fan is connected to the ventilation pipe. The photovoltaic, photo-thermal and lighting energy utilization device is simple in overall structure, achieves a concentrating photovoltaic, photo-thermal and lighting combination and increases the comprehensive utilization rate of energy.

Description

technical field [0001] The invention relates to a comprehensive utilization device with photovoltaic power generation, light heat and daylighting energy, which belongs to the field of optical technology application, green building design and comprehensive utilization of solar energy, especially the technical field of solar green building and solar combined light, heat and electricity supply. It can be applied to fields such as agricultural engineering and crop cultivation. Background technique [0002] In modern architectural design, more and more attention is paid to the adoption of new lighting and energy-saving technologies. At present, the most commonly used energy-saving building roof covers are transparent materials such as glass. The use of a large number of transparent materials can not only increase the visual comfort and design artistry of the building, but also make the interior of the building have good lighting during the day. However, the conventional transpar...
