Description

technical field [0001] The invention relates to a solar greenhouse building. Background technique [0002] 1. With the development of social productivity, energy shortage, greenhouse effect and environmental pollution have become global problems. Seeking new technologies for clean energy utilization has become one of the hot research technologies in the world. As a clean and renewable energy source, solar energy is almost inexhaustible for human beings. Among various renewable energy sources, solar energy is the most important basic energy source. Biomass energy, wind energy, water energy, and tidal energy all come from solar energy. At present, the solar thermal utilization technology is mature, and the industrialized ones are solar water heater and solar thermal power generation, while photovoltaic power generation and solar chimney power generation have broad prospects in solar power generation technology. Ordinary solar chimney power station (also known as solar therm...

Problems solved by technology

[0003] 2. Today's residential buildings consume a lot of energy, and building energy consumption accounts for nearly 40% of the total energy consumption of human beings. One or two layers of thin glass can't do much insulation at all. Over there, the boiler keeps burning and the radiators keep heating the room, and here the thin windows emit heat (like It’s a person wearing a big padded jacket with his arms open in the cold winter)! The second is that there are almost no sunshade measures in modern buildings, allowing the summer sun to pass through the balcony windows to heat the room, but the room can only be cooled by air conditioners

[0005] 4. The photoelectric conversion efficiency of a general photovoltaic cell is 10% to 20%. During operation, most of the unused solar radiation energy is absorbed by the battery and converted into heat energy except for a part of it being reflected; if the absorbed heat cannot If it is excluded in time, the temperature of the battery will gradually increase, and the power generation efficiency will decrease (according to statistics, the power generation power of the battery component will decrease by 0.4% when the temperature of the battery component rises by 1 degree Celsius), and the photovoltaic cell will age rapidly and shorten the service life if it works at high temperature for a long time.

It is the direction to adopt simple and effective heat dissipation measures for these components to reduce their working temperature, such as adopting an all-metal backplane (ZL200820200742. 9, CN201120084141. 8), but relying solely on the oxide layer on the surface cannot satisfy the needs of the backplane. The requirement of materials for long-term insulation makes the components face safety problems in the actual process. At the same time, the excessive thickness of the metal layer is not conducive to the transportation of components and reduces costs.

[0006] Searching Chinese and foreign patents, there are some designs on the surface of buildings and solar thermal power stations on the top, such as Chinese patent 2011103396740, an energy-saving building with a cooling structure, etc. The ventilation is well designed, but it is not enough for the building’s heat preservation, sunshade, and solar energy. Utilization is not in place
