How does solar energy keep warm?

Solar heating uses scattered solar energy to convert solar energy into convenient hot water through heat collectors, such as flat solar collector plates, vacuum solar tubes, solar heat pipes, etc., and deliver it to heating terminals, such as floor heating systems and radiator systems, to provide room heating systems.

The main working principle of solar heating is similar to that of our solar water heater, that is, solar radiation passes through the outer tube of the vacuum tube, is absorbed by the coating of the collector, and then is transmitted to the water in the tube along the inner tube wall.

Solar energy heating system involves a wide range, the system is complex, and the initial investment is large, so it is not suitable for individual construction now. If government policies and financial support are feasible.

Extended data:

Solar water heater devices usually include solar collectors, water storage tanks, pipes and other parts of water pumps. In addition, in winter, heat exchangers, expansion water tanks and power generation devices are needed in case the power plant cannot supply power.

Solar collector In the solar heat collection system, the device receives solar radiation and transfers heat to the heat transfer working medium. According to the heat transfer working medium, it can be divided into liquid collector and air collector.

According to the way of lighting, it can be divided into two types: concentrating heat collector and absorbing heat collector. Besides, there is a vacuum collector. A good solar collector should last for 20 ~ 30 years, and the collector made from 1980 should last for 40 ~ 50 years with little maintenance.
