We often see the solar water heating engineering system on the Internet. What are the general parts of the solar water heating engineering system? Generally, what role does it play in the whole system engineering
Collector:
Collecting solar auxiliary radiation energy to heat hot water is a key component of solar hot water engineering system. In the past, the solar collectors of the solar water heating engineering system in the North generally used multiple domestic solar water heaters in series and parallel. However, according to their different structural forms, they are generally divided into flat plate collector, vacuum tube collector, heat pipe vacuum tube collector and other forms.
support:

Since the solar angle is different in different places, the solar collector needs to better receive the sun. The support needs to install the solar collector according to different local latitudes, so it needs to be supported by a support. The supports are basically welded with section steel, and some are made of stainless steel. The support must be firm and firm。

Thermal system:
The utilization of solar energy is greatly affected by the outside world. In order to ensure its all-weather use, auxiliary heating method should be used when the solar energy can not reach the water temperature. Some common auxiliary heating system equipment include electric heating, air energy heat pump, various boilers, gas heating, coal burning, etc.
Hot water tank:
Due to the influence of weather, geography and other factors, the solar radiation is unstable and discontinuous, and the instantaneous energy is low, so the energy must be accumulated continuously. Therefore, it is required to be equipped with a heat preservation water tank. Thermal insulation water storage tanks generally have stainless steel water tanks, steel water tanks or even cement water tanks according to their different materials. The thermal insulation materials generally use polyurethane foaming materials. But the important principle is not to cause water pollution, and the insulation is good.
control system:
The solar hot water project must meet the needs of users according to their different use requirements, that is, it needs to design different operation modes to control the water temperature, water volume, pressure, heating mode, etc. the control system generally has manual control and automatic control。
System piping:
The solar hot water engineering system continuously obtains heat under the sunlight and circulates heat according to its different operation modes. Therefore, it is necessary to install its pipes, valves, pressurized circulating pumps, etc. in the system to form the pipeline system of the hot water engineering. The selection of system pipeline, the rationality of installation and the quality of insulation will directly affect the thermal efficiency of the system.
Anti corrosion and thermal insulation:
The vast majority of solar hot water projects are installed in the open air, where the temperature difference between cold and heat is large. In order to ensure the normal use of the system and a certain service life, it is necessary to carry out anti-corrosion and thermal insulation for the exposed parts such as supports and pipelines.
Generally, the solar hot water engineering system is the above several important components. The hot water engineering system designed by different companies will be different, but these main parts are essential.
