1. Specification of non-pressure solar water heaters:
Vacuum tube:
1.1.6mm thickness borosilicate glass 3.3
2. AL-N-AL or Cu-AL-SS coating
3. Tube pressure: 5× 10-3PA; Absorptance≥ 0.91
Water Tank:
1. Inner tank: 0.4mm thickness SS304 stainless steel
2. Outer tank: 0.4mm thickness SS304 stainless steel or color steel
3. Absorbing layer: High-pressure polyurethane foam with 50mm thickness
4. Foaming density: 35g/cm3; Closed-cell foam rate: 95%
5. Capacity: 100L-360L
Bracket:
1. Galvanized steel or aluminum alloy with 1.5mm thickness;
2. Angle of stand: 18° , 20° , 38° , 45°
2. Working principle:
There is water in the vacuum tubes and free to flow into tanks. When the water in the tubes is heated by the sun's rays firstly, this makes water in the tubes lighter. Therefore, the cold water in the tank move downwards and hotter water move upside into the top of the tank. It is an open circuit since the air vent and the overflow pipe is open to the air.
3. Applications and features:
1. Solar water heater use the free energy-sunshine to supply hot water, it could help us to save money.
2. The heat preservation of water storage tank is 72 hours, so if there is no sunshine, it also could supply hot water.
3. Non-pressure solar water heaters are widely used in family supplying hot water: Washing machine, kitchen, shower and so on.
4. Also, the non-pressure solar water heaters could be used for all kinds of projects, such as, community projects, school projects, hotels, factories.
