Hotel Flat Roof Used Concentrated Evacuated Tubes Heat Pipe Solar
Collector for Split Heating System
Heat pipe solar collector working principle
1) Solar absorption: solar radiation is absorbed by the solar tubes
and converted into heat.
2) Solar heat transfer: heat pipes conduct the heat from within the
solar tube up to the
header pipe.
3) Solar energy storage: water is circulated through the header,
via intermittent pump cycling.
Each time the water circulates through the header, the temperature
is raised by 5-10C.
Throughout the day, the water in the tank is gradually heated.
Features:
1. The water can be heated by the heat pipe rapidly.
2. Save place and easy to install.
3. Perfectly combined with architecture.
4. No water flow into the vacuum tubes, the tube won't break in
winter.
5. Stable performance. It can still operate in the event of
occasional tube breakage.
6. The water tank need not be installed higher than the collector.
7. Ideal for commercial solar water heating applications.
8. It is available whether the roof is pitch or flat.
9. Low maintenance effort.
