Evacuated Tube Solar Collector Details

Model:FD-SC-12-PRO

SPECIFICATIONS OF THE FADI PREMIUM SOLAR COLLECTOR

Description

The FADI premium collector is a thermal solar collector that uses
twin glass evacuated tubes as the solar absorber. Copper heat pipes are used to
transfer the heat from within the evacuated tube to a heat transfer manifold, with
metal fins positioned within the evacuated tube to aid heat transfer and hold the heat pipes firmly in place.

The heat transfer manifold consists of a copper header pipe through which
heat transfer liquid (water or water-glycol mix) is circulated. The header is designed
with dry contact ports into which the heat pipes plug, allowing efficient heat transfer.
There is no water inside the evacuated tubes and no direct contact between the heat
pipes and the heat transfer liquid, as such the system is suitable for mains pressure.

The manifold and tubes are attached to a 3.0mm thickness aluminum alloy mounting frame,
which can be mounted directly on a roof of suitable pitch. Frame kits are also
available which allow mounting on flat roofs, walls or low-pitched roofs. By using
commercially available frame kits, pole mounting is also possible.

The FADI solar collector has been designed to be suitable for a
wide range of system configurations including open loop, closed loop, drain back and
even thermal siphon when coupled with a suitable tank. Collectors may be installed
in banks of up to 10 collectors in series (300 tubes maximum) and unlimited parallel-
connected bank.

Evacuated Tube Solar Collector  working principle:

1. The heat pipe series pressurized solar collector are always connected with existing heating supply device.

2. The selective coating on the inner Cover of the evacuated tubes converts solar energy into heat energy and transfers heat to the heat pipes by aluminum fins.

3. The liquid in the heat pipe changes into vapour which rises to the condenser.

4. The heat then passes through the heat exchanger and the vapour becomes liquid, returning to the base of the heat pipe.

5. The heat conducts to the heat transfer liquid (anti-freezing liquid or water) via a copper pipe.

6. This transference of heat into the liquid creates a continuous circulation as long as the collector is heated by the sun.
