We use
four seasons constant temperature coating technology,
To minimize the color difference.
Ousikai vacuum tube has
*5years long life span ,and the vacuum tubes can work
individually,so if the only
one of them can't work,it won't influence on the
others.The spare parts can
be changed freely .it is suitable for the many
residentbuildings.
Solar vacuum tube working principle:
1,The high quality vacuum tubes ansorb the solar ultraviolet
ray;then heat the
cold water in the vacuum tube
2,The hot water rise in the top of the water tank ,and the cold
water sink to
bottom,then heat by solar collector.so the whole system is always
circulating
continuously.
3,The electromagnetism or ball valve can perform the water supply
automatically,the
water in the tank is not sufficient ,the electromagnetism valve
will open its valve,
the tap water flow in the tank ,if the water is full,it will
close the valve automatically
Solar vacuum tube
features:
1. High heat
effectiveness: higher than all glass evacuated solar collector
tube by *5%
2. heat
pipes conduction: successfully prevents the defects of tube
breakage and low power output caused by water fouling and
deposits or dust and sand
3.
Prevents the tube from being easily broken caused by volume
expansion when water freezes in the frigid season
4. Low thermal
capacity makes the tube start up quickly
5. Energy
output within only 2 minutes of sunshine
6.
Insulation temperature can reach **0deg;C, average heat
efficiency can still be more than *0%; even under
**0deg;C
