Non pressure ETC solar collectors

Working principle

The design of this type solar collector use the all-glass three targets vacuum tubes as the heat-absorb element. The high vacuum degree of the clearance between the outer and inner tube can reduce the heat emission which caused by convection and conduction to a very low level. All-glass evacuated tube transfers sun energy into heat energy by the high absorption rate and low emittance rate of layer films (Cu/Al/SS). Depend on thermo-siphon principle, the different density between the hot water and the cold water, a cycle can be created in the tube which hot water ascending and cold water descending status. Keeping natural circulation like this, the water in the manifold will be heated hotter and hotter.

 

Characteristics

1. Applicable to solar hot water supply/ swimming pool heating/ commercial water heating.

2. Operates automatically, telecommuting controlling.

3. The design allows for versatile architectonic integration.

4. Strong adaptability

5. Wide application occasions

6. Economical and practical

7. Environmental conservation and energy saving

8. In large-scale projects, we use many-tubes-connected solar collecting system that is composed of solar collectors, storage tank, auxiliary heating system, computerized controller and pipe cycling system

9. with large heat collecting capacity and hot water output

Water pipe connect

Manifold has two water connectors, water inlet and outlet. Solar collector connect to water storage tank, when water circulate, the hot water in the solar collector will flow to the water tank, cold water will flow to solar collector and heating.

Maintenance:

Maintenance of the system is very easy and includes the following tasks:

1. Cleaning

Regular rain should keep the evacuated tubes clean, but if particularly dirty they may be washed with a soft cloth and warm, soapy water or glass cleaning solution. If the tubes are not easily and safely accessible, high pressure water spray is also effective.

2. Leaves

During autumn, leaves may accumulate between or beneath the tubes. Please remove these leaves regularly to ensure optimal performance.

3. Broken tube

If a tube is broken it should be replaced as soon as possible to keep the system working. Any broken glass should be cleared away to prevent injury.
