2.3. Protective heat-tempered solar glass
Durasolar® P+.
Diagram 3.
Solar-grade heat tempered glass
Durasolar® P+. The glass used in
SUNSYSTEM flat-plate collectors is
distinguished by decreased iron content
providing for better transparency to
the sun rays. Durasolar® P+ has prism-
textured surface, which directs even the
rays reaching the glass in unfavorable
angle straight to the absorber.
2.4.
Insulation
of rock wool keeps the
heat from leaving the collector body.
2.5. Durable construction
Diagram 4
The collector case is made of robust
aluminum frame, and the bottom is made
of
embossed aluminum sheet. This way
the collector body has the necessary
constructive strength to withstand
the year-round whims of weather not
sacrificing on light-weight
.
3. DESCRIPTION OF VTC TYPE
EVACUATED - TUBE COLLECTOR
3.1. Evacuated tube.
Absorber coating
Diagrаm 5
Evacuated tubes are two concentrically
positioned borosilicate glass tubes
enclosing a gap of evacuated air. The
internal glass tube is coated on its external
surface with an environmentally friendly,
highly selective layer and thus functioning
as an efficient absorber.
3.2. Heat-carrier pipe system
Diagrаm 6
Copper
heat-carrier tubes type
Heat Pipe
TU 1.
The pipe system is manufactured
with a minimum
number of welds for
perfect air-tightness and reduced
deposits
accumulation possibility.
Heat Pipe technology
is
characterized by
its
high efficiency:
improved heat-absorbing capacity of
collector, low heat losses and stable
performance in harsh climate
conditions.
