Large-area transmission condensation solar photoelectric photo-thermal daylighting building member quadruple coupling device

Abstract

The invention relates to a large-area transmission condensation solar photoelectric photo-thermal daylighting building member quadruple coupling device, which mainly comprises light transmission glass (1), a solar cell (2), a rectangular heat collection pipe (3), an inner plate (4), an outer frame (5), an angle changing mechanism (10) for regulating the change of a solar declination angle and a translation mechanism (11). The quadruple coupling device is characterized by combining four functions of solar photovoltaic power generation, the generation of heat energy, daylighting and building members. Under the irradiation of sun light, a plurality of groups of strip condensation belts of which the area is only a fraction to several tenth of the irradiation area of the sun light are formed on the condensation surface below the light transmission glass (1); the solar cell (2) is arranged on the condensation belts to reduce the using amount of the solar cell (2); and water (or air) in the rectangular heat collection pipe (3) which lean against the reverse side of the solar cell (2) is cooled to carry away heat, so that the temperature of the solar cell (2) is not high. The large-area transmission condensation solar photoelectric photo-thermal daylighting building member quadruple coupling device realizes one device with four purposes, is low in cost and does not occupy lands. Electric energy, heat energy and daylighting which are generated by utilizing the quadruple coupling device serving as the building members such as roofs, windows, walls and the like at the sunshine position can be supplied to the production and living of people.

Description

technical field [0001] The invention relates to a large-area transmission and concentrating solar photoelectric photothermal lighting building component quadruple device, which is not only an energy conversion device that converts solar energy into electric energy and domestic heat energy at the same time, but also a building component, which belongs to solar energy. The technical field of photovoltaic solar thermal building integration. Background technique [0002] With the increasing energy consumption, the increasing shortage of fossil energy, and the increasingly serious environmental pollution, it has attracted the attention of most governments and people in the world. ", proposing to restrict the emission of industrial waste gas by various countries to control global warming, has become the principle of shared responsibility recognized by the United Nations. China became the world's largest greenhouse gas emitter in 2007. In 2008, China's energy consumption was secon...

Problems solved by technology

[0004] The research on solar photovoltaic power generation / photothermal cogeneration devices began in the world in the 1980s. Later, some scholars also proposed some technical solutions, and through experiments and calculations, they have achieved good cogeneration effects. , but the glass cover plates in the same technology basically use transparent flat glass. Since this flat glass has no light-gathering ability, its disadvantages are as follows: first, it needs to use a large number of expensive Solar cells, which lead to the high cost of solar photovoltaic power generation, and secondly, in order to prevent the loss caused by the reduction of the working voltage and output power of solar cells due to the increase in temperature, and at the same time take into account the purpose of "waste heat" utilization, it must be within the range of the incident sunlight area The back of each solar cell in the solar cell must cover the heat exchange device, which has caused problems such as large coverage of the heat exchange device and low heat temperature, so its promotion and application prospects are not optimistic.
