Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and implementation examples.

[0021] figure 1 It is a structural schematic diagram of a louver-type solar concentrated photovoltaic / photothermal / illumination integrated system of the present invention. Its main structure includes: bracket (1), concentrating blades (2), reflective film (4), solar thin film battery (7), fins (8), cooling water channel (rotating shaft) (10), insulation layer (9 ). The connection relationship of each part is that the concentrating blade (2) is fixed on the bracket (1) through the cooling water flow channel (rotating shaft) (10), and the lower surface of the concentrating blade (2) is pasted with a reflective film (4) as a reflective surface. The solar thin film battery (7) is installed at the side edge of the concentrating blade (2), and the other side of the solar thin film battery (7) is a fin (8), an...

Abstract

The invention discloses a shutter type solar concentrating photovoltaic / photo-thermal / illumination integrated system, belonging to the application field of solar photovoltaic photo-thermal and building illumination. A traditional shutter only has the function of adjusting indoor illumination, and solar radiation entering a window body cannot be utilized. In order to realize utilization of solar energy resources in a vertical space and reduce building energy consumption, the invention provides a design method of a light-gathering shutter capable of generating electric power and household hot water by utilizing a window body. According to the invention, the upper surfaces of condensation blades are designed to be total reflection surfaces, and the lower surfaces of the condensation blades are reflection surfaces; when light rays within a certain angle range enter the blades, the light rays can be converged to the lateral edges of the blades covered with solar thin-film cells, and the cells convert light energy into electric energy; the cells are cooled by cooling water, so household hot water can be obtained while the temperature of the cells is prevented from rising; and by adjusting opening and closing angles between the blades, on one hand, the sun can be tracked, and on the other hand, indoor lighting requirements are not affected.

Description

[0001] Technical field [0002] The invention relates to a louver-type solar concentrating photovoltaic / photothermal / lighting integrated system, which is a system formed by combining concentrating blades with photovoltaic cells and photothermal units, and realizes photovoltaic, photothermal, Lighting integrated solar composite utilization. It belongs to the application field of solar photovoltaic photothermal and architectural lighting. Background technique [0003] Construction, industry, and transportation are called the three major energy-consuming industries. At present, the total energy consumption of buildings in my country accounts for about 20.7% of the total energy consumption of the society. Moreover, as people's pursuit of a better life continues to increase, this proportion will become higher and higher. Building energy consumption is mainly concentrated in lighting, air conditioning systems, hot water and other aspects. Applying solar energy utilization techno...
