Solar hot water, usually refers to the sun radiation energy, in the modern generally used for power generation. From the earth to the sun forming a biological mainly provide heat and light survive, and ancient human also understood to dry in the sun, and keep food items as the sun methods, such as salt and salted fish, etc. But in the fossil fuel reduction of, just to put solar further development. The use of solar energy have passive use (solar-thermal conversion) and photoelectric conversion in two ways. Solar power a new kind of renewable energy. In the broadest sense of the solar is the earth many energy sources, such as wind, water, chemical potential energy, etc.
Solar water heater is by vacuum tube, temperature-holder box, brace, connect the system pipelines of the collectors components. Its function is equivalent to the heating tube solar collectors . And water heaters, gas water heater is different, solar energy collector use is the sun's radiation heat, so the heating time only in the sun. The popularity of the Chinese market at present is whole glass solar-thermal vacuum tubes. Structure is divided into outer pipe, tube, the selective absorption coating, getter, stainless steel clip next, vacuum sandwich etc parts.
But foreign mature collectors are solar panel , flat collector has long life, high stability, recyclable advantages, but due to a higher vacuum tube collectors cost tallish, domestic production of many of the low prices flat collector performance really bad, so be domestic mainstream solar manufacturers distorted the flat collector performance. But flat collector in the solar industry development unstoppable, not by some manufacturers of misleading can kill. Now many design institute of the water supply and drainage designers have realized the problem.
The solar energy water heater working principle: solar water heater is solar achievements of great industry, its application in environmental protection, safety, energy saving, health and other advantages, quickly won the favor from the masses of consumers, China, is an energy consuming nations, annually national energy consumption of the world total energy consumption of about 1/3, but the national total energy consumption, have 1/3 is from building energy consumption. "To the roof to energy", solar water heater is absorb solar radiation heat energy, heating cold water offer people in the life, the energy saving equipment used in production.
