Ultra-efficient electricity and heat cogeneration BIPV integrated assembly, and heat and power cogeneration system thereof

Abstract

The invention discloses an ultra-efficient electricity and heat cogeneration BIPV integrated assembly, and a heat and power cogeneration system thereof. A BIPV assembly main body comprises a heat collection flat plate, a solar cell and a transparent glass cover plate, a circulating pipe and a bottom frame assembly are arranged on the heat collection flat plate, the heat collection flat plate is formed by combining a plurality of whole aluminum plates, and the space between the circulating pipe and the heat collection flat plate is filled with a heat conduction piece; the system comprises the ultra-efficient electric heating cogeneration BIPV integrated assembly and a heat collection and heat preservation water tank, the BIPV integrated assembly is communicated with the heat collection and heat preservation water tank through a pipeline, the BIPV integrated assembly is connected with the heat collection and heat preservation water tank through the pipeline to form a circulation loop, and heat is supplied to the outside through the heat collection and heat preservation water tank. According to the invention, the defect that the solar photovoltaic panel is bulged due to long-term exposure outdoors can be well overcome, the defect that the solar photovoltaic panel is bulged during overall briquetting in the production process can also be overcome, the service life of equipment is greatly prolonged, heat of a solar photovoltaic panel can be fully utilized, and greenness and environment-friendliness are achieved.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to an ultra-high-efficiency cogeneration BIPV integrated component and a cogeneration system thereof. Background technique [0002] It is known that solar energy is an inexhaustible renewable energy source. In recent years, with the pressure of environmental protection and technological progress, solar photovoltaic power generation technology has become increasingly mature. Generally, the maximum photoelectric conversion efficiency of photovoltaic cells is only about 15%. Most of the unused solar radiation energy is absorbed by the battery and converted into heat energy. It will gradually increase, the power generation efficiency will decrease, and the service life of photovoltaic cells will be shortened due to rapid aging when working at high temperature for a long time. And building integrated photovoltaic (Building Integrated Photovoltaic, BIPV) is the combinati...

Problems solved by technology

[0004] In short, although the above also shows that the cogeneration photovoltaic panels have reliable insulation and effective heat transfer, but because they are installed outdoors, they will face the four seasons of the year, especially after long-term use due to The thermal expansion and cold contraction of the aluminum plate and the glass are different, resulting in the phenomenon of drumming (arching) on ​​the surface, and at the same time, drums (arching) will also appear when the existing overall compact (laminated into a heat-collecting chip) during the production process ) phenomenon, which will not only make the use effect of the overall cogeneration photovoltaic panels not good, but also shorten the service life of the equipment, which will inevitably increase the user's cost input
