Solar thermal collector composite panel and building integrated wind-thermal solar system

Abstract

The invention discloses a solar heat-collecting composite board and a building-integrated wind-heat solar energy system. The solar heat collection composite panel includes a metal bottom plate and a metal top plate. The periphery of the metal bottom plate and the metal top plate is sealed and connected by a sealing plate. For the hot air duct, the sealing plate is provided with an air inlet and an air outlet connected to the heat collecting air duct; the outer surface of the metal roof plate is sprayed with a structural coating integrated with heat collecting and foaming heat preservation. The composite board adopts heat collecting and foaming thermal insulation integral forming structural coating, realizes the perfect combination of heat collecting layer and thermal insulation layer, and has the advantages of low cost, good performance, strong decoration, good anti-corrosion, heat preservation and weather resistance. The air heating, heat preservation, weather resistance and other performances of the composite panel can be realized through the integrally formed structural coating, without the need for complex panel structure, and the structural design is relatively simple, which facilitates the integrated design of the air heating system and the building.

Problems solved by technology

[0002] In the new solar energy industry, traditional solar energy uses vacuum glass tubes to convert energy into hot water. The equipment is cumbersome and easily damaged. There are limitations in the area, and the area used is extremely limited, which cannot solve the problem of large amounts of hot water or heating

[0003] Traditional solar energy uses vacuum glass tubes, which requires a large investment, and the heat generated is generally at 95°C. It can only be used for simple small-scale water heating. Especially in places with poor water quality, scale is easily generated, resulting in lower solar energy utilization.

On the other hand, the split solar structure not only affects the beauty of the building, but also has a large energy loss during the conduction process, and the split structure of the building will also lead to multiple constructions, which will increase the investment, especially the traditional solar energy. The heating area is small, which can only meet the small demand of hot water, and the energy conversion is low

Moreover, traditional solar energy belongs to water heating. If it is used on a large area of ​​the house, it will directly increase the load bearing of the roof and indirectly pose a safety hazard.
