3 TZ58-1800 Heat Pipe Solar Collector
The Firebird TZ58-1800 Heat Pipe Solar Collector is the latest
addition to the Firebird solar range and offers an optimum
performance to price ratio. Built to Firebird’s exacting standards,
they have an extremely high efficiency and can deliver solar energy
even in overcast weather conditions.
How the TZ58-1800 Heat Pipe Solar Collector works
The TZ58-1800 Heat Pipe Solar Collector consist of a
borosilicate glass tube with a near-perfect vacuum and a
selective absorber coating applied to its inner surface.
A copper heat pipe is located inside the heat pipe which
contains an alcohol-type fluid that can evaporate
at temperatures as low as 25˚C.
Solar energy is absorbed onto the absorber surface
on the glass tube and then transfers to the heat pipe, causing the alcohol-
type fluid to heat up and turn to vapour. As the fluid evaporates it rises to the top of the heat pipe,
known as the condenser section. Here it condenses back to a fluid state and releases latent heat which is
transferred to the heat exchange fluid, passing through the upper manifold. The condensed liquid flows back
to the bottom of the heat pipe to, once again, repeat the process.
Key features of the TZ58-1800 Heat Pipe Solar Collector
•
High build quality - aluminium manifold design,
nickel plated condenser head, borosilicate glass.
•
High efficiency vacuum tube - round shaped
absorber tube ensures solar energy is captured
throughout the day.
•
Heat pipe technology - manifold can be
installed initially and tubes added later
during commissioning.
