摘要:
A solar power platform on water is provided, which includes photovoltaic-photothermal solar collectors and an over-water floating platform or an embedded floating platform having a fixing structure. Each of the photovoltaic-photothermal solar collectors has a glass cover tube structure and is equipped with a cooling circulation system. The photovoltaic-photothermal solar collectors are connected and disposed on a surface of a mounting platform higher than a sea wave height and configured into a matrix facing an incident direction of sunlight, and incorporated in and electrically connected to an on-land power grid via a controller/inverter for direct power supply, or electrically connected to a rechargeable battery set for indirect power supply through stored energy. As the solar power platform on water is adopted, the wind load is greatly reduced, the anti-storm performance is greatly improved, and the self weight as well as the construction and maintenance cost are greatly reduced. In addition, the solar power platform on water can be disposed over a water surface of a shallow water area close to coastal districts, so that the power loss on the transmission and transformation cables is reduced, and the solar power platform on water is applicable to a wider range of water areas than the prior art.

摘要:
A method for producing hot water and a device especially for carrying out the method are provided. The method utilizes combined heat resources of solar energy and heat pump in the manner of heating water at multiple stages and accumulating energy. The device comprises a solar energy collector, a heat pump, an electrical heater, a water tank, and a control unit. The device also includes water-heating tanks with multiple stages. A heating means with multiple stages at different temperatures is formed either by the solar energy collector or by the collector and the heat pump. The outputting end of the two or more heating stages constituted by the solar energy collector or by the collector and the heat pump is connected through ducts to the corresponding water-heating tanks. A predetermined amount of produced water heated at multiple stages is respectively stored in the water-heating tanks. Compared with the prior art, the present invention is endowed with the performance of making use of the solar energy to the greatest extent and utilizing off-peak electricity more efficiently as a supplementary heating means. Furthermore, the arranging fee of the device is reduced and its adaptation of mounting is improved.
摘要:
The invention relates to a hanging transparent glass vacuum tube type solar heat collecting unit, including heat collecting tube plate, transparent glass tubes and seal cover, characterized in that further comprising multiple fins disposed along the axial direction of the glass tubes, wherein, said fins comprise a base plate and a faceplate coupled thereto. The fin plates are coupled to the heat collecting tube plate plane through the base plate, and are arranged at an angle with the heat collecting tube plate. Since several parallel radiation absorption fin plates with a certain angle to the heat collecting tube plate are distributed on the light-absorbing surface of the hanging transparent glass vacuum tube solar heat collector, the absorption ratio is approximately 1 in hanging installment. Only a fine angle adjustment or no angle adjustment to the heat collector is required to enhance the harmoniousness with the buildings and avoid the disadvantages of heat dispersion and heat transfer, which gives a better effect in sunlight energy collection and heat transferring than the prior art.
