Solar water heating system and running method thereof

Abstract

The invention relates to a solar water heating system. A high-temperature probe is arranged on the outlet of a flat-plate solar heat collector, and the outlet of the flat-plate solar heat collector is connected with the inlet of a liquid separation bag; the outlet of the liquid separation bag is connected with the inlets of solar water heater circulating pipes of users of each unit respectively; the outlets of the solar water heater circulating pipes are connected with an anti-freezing working medium return pipe; a solar water heater is placed in each user; a circulating pump is arranged at the high-end position of the tail end of the outlet of each of the circulating pipe; a pressure transducer is arranged on the outlet of the circulating pump; the pressure transducer is connected with the inlet of the flat-plate solar water heater, the outlet of a liquid compensation pump, the inlet of a safety valve and the inlet of an electromagnetic valve; a low-temperature probe is arranged at the low end of the anti-freezing working medium return pipe and connected with the inlet of the circulating pump; and electric control signals of the circulating pump, the liquid compensation pump, theelectromagnetic valve, the pressure transducer, the high-temperature probe and the low-temperature probe are connected with an electric control disc. In the solar water heating system, by using natural energy, the normal energy cost can be saved by 60 to 80 percent.

Description

technical field

[0001] The invention relates to a comprehensive utilization of solar energy, in particular to a solar water heating system and an operation method. Background technique

[0002] Human life and production consume a lot of energy. Without sufficient energy supply, human beings cannot survive. So far, most of the primary energy used by human beings—coal, oil, and natural gas—are mined from the earth under their feet. However, no matter how big the earth is, it is limited, and conventional energy sources will be exhausted one day. With the rapid growth of population and rapid economic development, the rapid consumption of natural resources will further shorten the time for human beings to rely on conventional energy. Conventional energy sources are all fossil fuels, which will inevitably emit a large amount of greenhouse gases (such as carbon dioxide) and harmful gases (such as sulfur dioxide that causes acid rain), various natural disasters caused by the globa...
