SLU solar collector Operational Principle
The selective coating on the inner cover of the evacuated tubes ensures high energy absorption and low heat radiance loss, which converts solar energy into heat energy and transfers heat to metal U tube by an aluminum fin. The liquid (anti-freezing liquid or purified water) in the metal U tube is heated, and conducts the heat energy to the water inside the storage tank through plate exchanger or internal spiral coils.
SLU solar collector Features
- Utilization all year round even in cold climates;
- Can operate with water pressure up to 0.6MPa;
- Annual heat gain 576 kWh/m
2
(tested in ITW-Stuggart, Germany);
- The collector will still operate in the event of occasional tube breakages;
- Modular system means easy handling, installation and can be extended to cover larger areas;
- Easy to install on roofs, balconies or façades;
- Can be combined with existing energy source;
- Quasi-tracking in all seasons.
- The diffuse flat plate reflector unit behind the glass tubes can be easily assembled and increase efficiency by 5%;
