Maintaining The Vacuum Inside The Tube

During the manufacture of the tube, the air between the two tubes is extracted or removed from the space between tubes to form a vacuum, which eliminates heat loss by conduction and convection. To maintain the vacuum inside the tube, a barium element is exposed to high temperature, which causes the bottom of the tube is covered with a layer of pure barium (silver). This layer of pure barium, is a visual indicator of the internal vacuum tube. If the color turns white silver the vacuum is lost and the tube has to be replaced. Evacuated tube components: 1. Outer tube 2. Inner tube 3.

Empty 4. Selective surface (aluminum nitrate) 5. Gletter barium (element maintains the vacuum absorption) 6. Another layer of pure barium kind of pipe is known as “heat-pipe working fluid in this type of tube is a low-glycol specific heat, which is contained in a copper capillary tube inside the vacuum tube plate absorption tube “heat pipe” is inside a glass tube which has evacuated the air to eliminate heat loss by conduction and convection. The absorber plate is made from a semiconductor coating, this special coating suitable screening to operate in high vacuum ensures high energy absorption and low loss by radiation, the result is a high utilization of available energy What are the benefits of a solar heater? Solar water heaters provide more benefits than a conventional furnace or boiler. The main tangible benefit is the savings that this equipment to stop buying gas. Another equally important benefit is the contribution that a solar heater is on reducing greenhouse gas emissions to the atmosphere (carbon dioxide, CO2), creating a healthier environment. With a solar water heater will prevent the emission into the atmosphere over 3 tons of CO2. How I can save with a solar heater? The savings you can expect from a solar water heater depends on several factors, such as team size, the amount available in your area, and very importantly, the amount of hot water they occupy and how the squatters. The minimum savings in residential equipment is 80% in the current gas consumption for heating water holding. The system pays for itself on average in one year and eight months.
