Embodiment Construction

[0028] Through the following table [2] We can get the theoretical basis for power generation in cities: when the city is at an altitude of 10m, the general areas where wind power can be used for power generation are: rich areas, relatively rich areas, and usable areas. Wind energy power density is 100∽250W / m 2 .

Abstract

The invention provides a wind power generation system for high-rise building, which relates to the utilization of new energy resources. The invention is intended to provide a wind power generator with simple structure and low cost which can adapt to the utilization in cities. In order to remove the defects that the existing wind power generation system is not suitable because of low average wind power and insufficient empty space, the invention utilizes the wind power that acts on the facade of construction in city and realizes the power generation in urban area by installing specially designed power generation device on the ventilation stack (in west-east or north-south direction), top storey of building, technical interlayer or between the high-rise buildings.

Description

technical field [0001] The invention relates to a wind-driven generator, in particular to a tunnel-type diffuser-collection composite two-way wind-driven generator used in the space inside a building wall, on the roof of a building or in a technical interlayer, or between high-rise buildings. Background technique [0002] Wind energy, as a clean and abundant renewable energy, has been paid more and more attention by countries all over the world. China's wind energy reserves are large and widely distributed, and the wind energy reserves on land alone are about 253 million kilowatts. With the development of the global economy, technological progress and environmental protection, the wind energy market has also developed rapidly, and wind power generation will be fully competitive with coal-fired power generation commercially. Regardless of the economic and social benefits of the wind power industry, or China's current strategy of sustainable development and energy conservatio...
