External shading parabolic-reflector sun-tracking solar collector integrated with building

Abstract

An external shading parabolic-reflector sun-tracking solar collector integrated with a building belongs to third types of solar utilization equipment and is combined with building external shadings to avoid main energy consumption of air conditioners due to direct sun exposure in summer. By using reflectors, illumination area unobtainable by other ways is obtained at the lowest cost, heated pipes are exposed to light with intensity many times of that of direct solar radiation, and as heat transfer speed is proportional to temperature difference, daily average heat efficiency of the collector can be improved greatly under the action of high heat of the heated pipes, especially in winter. The external shading parabolic-reflector sun-tracking solar collector is a new growth point of solar industry. Water supply pressure also serves as sun tracking power for the reflectors, and the whole external shading parabolic-reflector sun-tracking solar collector needs no external power. One external shading parabolic-reflector sun-tracking solar collector can be used in a single-storey house or added to a middle storey of a multi-storey building, and the solar collector can be mounted in a window cover type to shade sun and heat water. A plurality of reflectors of multiple solar collectors in a same row or column can be driven to track sun by one drive system, so that cost is reduced, and the buildings become predominant renewable energy buildings.

Description

(1) Technical field: [0001] Integrated with the building, the external sun-shading parabolic reflector and the sun-tracking solar collector, the combination of external sun-shading energy saving in summer, solar energy utilization in winter and building integration make the building a green building that complies with the Energy Conservation Law and the Energy Conservation Regulations of Civil Buildings. Low-carbon, environmental protection and energy-saving technologies. (two) background technology: [0002] The flat plate type was first used in solar collectors, but due to many shortcomings such as low efficiency and high cost, the development is very slow. The emergence of the vacuum tube type has improved the thermal efficiency with the characteristics of the thermal well, and its practical value has enabled the rapid development of solar energy utilization and has become a huge industry. Due to the vacuum tube structure, it is difficult to use it on the vertical wall o...
