Vacuum Tube Solar Water Heater Producer are widely active in order to be able to offer these products among the applicants and to produce them from the advantages and consumption features of these products. The manufacturer of solar water heaters, produce with the help of vacuum tube technologies. They can easily provide the hot water used by the families.
What Is Vacuum Tube Solar Water Heater?
Vacuum tube water heater: They use the solar energy stored by the sun to generate heat to heat water for domestic and commercial needs. In the last 20 years, the purchase of solar water heaters has received much attention, especially in areas with hot climates and advanced in coating technology. The use of solar water heaters is more cost-effective and more energy-efficient than their counterparts, which use electricity, gas and heating.
In fact, the main part of a solar water heater is its collector, which consists of a sheet that is heated by sunlight and transfers its heat to an absorbing fluid such as water flowing inside the tube. direct flow evacuated tube collector It consists of a number of transparent double – walled pipes in which there is a tube with a cover of absorbent material. Air escapes from the space between the two walls and the vacuum created prevents heat loss. The advantage of this type of collector is the ability to generate higher temperatures.
Vacuum tubes consist of a double-walled tube that we place between the double-walled vacuum. The inner wall is lined with absorbent coating. Water fills the vacuum tubes. As a result of the sun’s radiation, the absorber wall of the sun’s energy heats up, and subsequently the heated water inside moves upwards, creating a thermosyphonic flow naturally. In vacuum tube technology, energy absorbing coating material is important.
In systems with a filling source, the water heater tank is connected to the city water network by a filling source equipped with a water float, and water enters the tank as an attachment for consumption.
This material is either made of AL, Cu, SS, (steel) or a nickel Ni element. In terms of quality, the three-element coating has a better efficiency than the single-element coating. In the figure below, Figure A has a three – element coating. Another important point is the thickness of the vacuum tube glass, which varies from 1.6 to 2.5. The thicker this is, the less likely it is that the pipes will break.
In addition, compensatory water supply is the responsibility of the expansion tank. Metal retainers include a metal frame that is responsible for maintaining the tank and absorber surfaces.
How Vacuum Tube Solar Water Heater Works Differently?
The main applications of solar thermal energy are currently heating pool water, water heating for local applications and space heating of buildings. For these purposes, the main task is to use plate absorbers such as solar energy with fixed directions and positions. These systems use solar radiation to heat water. In this way, by exposing sunlight to the installed collectors, it causes the liquid passing through the collectors to heat up.
Evacuated tube solar is usually made of chromium oxide, which absorbs 99% of the sun’s rays. The current is transmitted by a thermosyphonic property or by an electric pump to a storage tank that is insulated and can also be double-walled.
Vacuum Tube Solar Water Heater Manufacturing Process Review
In the production of vacuum tube solar water heaters, the best equipment and paths are used, and in fact, it can be said that this type of product is used as the best offer for hot water supply in residential and commercial buildings, as you mentioned in the previous topic in the production process. This type of product uses components and equipment of the private sector that the quality of these materials is higher. Certainly, the quality and performance of this type of devices increase.
