Operation Principle
Evacuated tube converts solar energy into heat energy and transfers
it to U-type metal tube by aluminum fin. The liquid (water or
anti-freezing liquid) in the metal tube has been heated by the
solar radiation and conduct the heat energy to the water inside the
storage tank. The collector can work all year around even in cold
climate areas in combination with the use of the fossil fuel or
electricity.
Advantages
- Highly efficient absorber, improving daily average efficiency up
to 50%.
- Withstand pressure of 0.6 MPa, can be connected directly with
city water pipe.
- No water exists in the evacuated tubes. The solar water heater
can still work in the event of tubes breakage.
- Simple structure, easy to assembly and install.
- Can be used all year around in the cold climate.
- Can be used together with auxiliary electric booster.
- Automatically controlled.
- Large-scale solar hot water system can be installed either with
parallel connections or perpendicular connections. It can be
combined with the architecture and existing pipeline perfectly.
Parallel Connect CAU Features- It can still work in the event of occasional tube breakages.
- It can be applied in all climates.
