The invention provides a non-tracking composite planar double-side concentrating photovoltaic photo-thermal assembly for a building, and belongs to the technical field of building energy-saving and energy application. The composite planar double-side concentrating photovoltaic photo-thermal assembly is mainly composed of a reflecting plate, a cooling water pipe, a heat preservation component, a photovoltaic plate and a heat absorption plate. In order to improve the solar radiation intensity reaching the photovoltaic panel by using the reflecting plate and further achieve the purpose of improving the output power of the photovoltaic panel, the cooling water pipe is used for cooling the photovoltaic panel to achieve the purpose of improving the efficiency of the photovoltaic panel, and meanwhile, heat is collected into water of the cooling water pipe, and heat loss is reduced by adopting the heat preservation component. Through the design of the photovoltaic panels at the upper side andthe lower side and a condenser, the solar radiation receiving area is increased, the problem that an existing non-tracking type concentrating photovoltaic photo-thermal system is large in annual output fluctuation is solved, and high and stable annual output is achieved. Meanwhile, the structure is similar to a building envelope structure, and building integration is easy to realize.
Description
technical field [0001] The invention belongs to the field of building energy-saving technology and energy application, and relates to a non-tracking composite planar double-sided concentrating photovoltaic photothermal module, in particular to the photothermal and photoelectric conversion process of sunlight, building integration, and the realization of comprehensive utilization of solar energy . Background technique [0002] With the reduction of traditional energy sources and the intensification of environmental problems, the use of new energy sources has become an important content of research. Among new energy sources, solar energy is a clean and inexhaustible renewable energy source. my country is rich in solar energy resources, and the annual solar radiation received by the land surface is about 50×10 18 kJ, so the research and application of solar energy is of great significance. Photovoltaic thermal system is a system that can effectively utilize solar energy at mul...
