Solar collectors
transform direct and diffused
radiating energy from the sun into thermal
energy (heat).
For this to occur, sunlight must be captured by
the surface of the absorber. The latter consists
of a uniform network of tubes through which
heat is conveyed. The specific shape of the
collector prevents undesired heat dispersal into
the environment.
The accumulator tank
stores the hot water
until required. The accumulator tank should
be suitably sized so as to compensate for short
periods of adverse weather conditions.
The
structure
simplifies collector installation.
Several different types are available depending
on the desired installation. The fluid (domestic
water) circulates naturally due to the
thermosyphon effect, and transports heat from
the collectors to the accumulator tank.
The
solar heating system
for the production
of domestic hot water consists of the following
components:
• Solar collector/s
• Structure
• Solar heating circuit hydraulic fittings
• Solar accumulator tank
