Structure diagram of solar water heater (working principle and composition analysis of solar water heater system)
Suzhou solar water heater system may have problems during use, such as the inner tank of the water heater may burst. These are caused by improper operation by users. But in the use of Suzhou solar water heating system, you can understand the relevant working principle and component analysis!
The working principle of solar water heater:
The sun’s rays pass through one layer of glass and reach the second layer of black absorbing glass The thermosphere, which absorbs heat from the sun’s rays. Since the two layers of glass are really insulated, the heat transfer will be greatly reduced (radiation heat transfer still exists, but there is no heat conduction and convection). Most of the heat can only be transferred to the water in the glass tube, so that the water in the glass tube is heated, and the heated water becomes lighter, rises along the heating surface of the glass tube, and enters the heat preservation water tank. The low-temperature water in the water tank rises from the back of the glass tube into the glass tube for replenishment and is used for hot water.
Components of a solar water heating system:
The collector element in the system. Its function is equivalent to the electric heating tube in the electric water heater. Different from the analysis of electric water heaters and gas water heaters, solar collectors use the sun’s radiation to generate heat, so we can work and study through the heating system only when the sun’s irradiance reaches a certain value, so as to improve the performance of enterprises. . At present, all glass and solar real empty heat collector tubes are the most common in my country’s economic development. The structure can be divided into an outer tube and an inner tube, and the outer wall of the inner tube is coated with a selective knowledge-absorbing material coating. The flat plate collector is coated with heat absorbing film such as black chrome, and the metal tube is welded on the heat collecting plate. The cost price of the flat plate collector is slightly higher than that of the vacuum tube collector. In recent years, flat plate collectors have shown a rising and falling trend in China, especially in the solar water heater technology of the company’s high-rise buildings.
