Pressurized Solar Water Heating System |
| |
Evacuated tube technology delivers significantly better performance than traditional
absorbers in the market today. Their advanced design incorporates tubes that consist
of 2 layers of borosilicate glass with a vacuum layer between them. This vacuum acts
like a thermos flask, retaining up to 97% of the thermal energy, resulting in increased
efficiency. The sun’s thermal energy is then transferred to the manifold via the heat
pipe located inside each tube.
The small amount of evaporative liquid in each tube is super heated by the sun’s
energy and forms a vapour. The vapor rises to the top of each pipe; this heat is then
transferred to the water flowing through the manifold. The heated water is then
returned to the tank. The cylindrical design of the tubes ensures effective collection of
the sun’s thermal energy throughout the day. |
