Description of Evacuated-tube collector - VTC
2.1. Evacuated tube. Absorber coating.
Diagram 1
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.
2.2. Heat-carrier pipe system
Diagram 2
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.
Diagram 3
Heat carrier fluid runs from evacuated tubes to the manifold pipe and hence
the system.
Both outlets of Manifold pipe
can be connected as heat-carrier input or
output in any direction.
2.3.
Temperature sensor
can be mounted left or right, depending on the
position of the heat-carrier outlet.
2.4.
Heat transfer plates
resistant to high temperatures of stagnation
.
2.5.
High-efficiency insulation of collector pipe.
2.6.
Durable construction
made of resistant to harsh climatic conditions, materials.
