The AURON DF solar hot water
heating
system is comprised of the
following components:
•
solar panels
•
mounting rack
•
heat transfer fluid
•
expansion tank
•
solar storage tank
•
solar pump with flow limiter
•
solar controller including tempera-
ture sensors for collector and stor-
age tank
•
air separation tank, vent, safety
valve and miscellaneous parts
The AURON solar energy system
may also be used to support a central
heating system if a suitable storage
tank and solar controller are selected.
The AURON DF solar collectors
con-
vert direct and diffused sunlight into
heat. The energy radiating from the sun
is absorbed by the absorption surface
of the collector. An associated piping
system transfers the heat away. The
vacuum inside the tubes and the design
of the collector minimize heat loss to
the surrounding environment.
The
Solar controller
controls the entire
system. As soon as the collectors be-
come hotter than the lower part of the
storage tank due to the absorbed solar
energy, a circulating pump is switched
on and the heat is transferred to the
storage tank. The pump is shut off
when the collector temperature falls
below the temperature in the storage
tank. To prevent boiling in the storage
tank, the pump also shuts off when the
temperature in the storage tank has
reached its maximum rated level. Sys-
tem operation is fully automatic.
The
air separation tank and manual
vent
ensure that the solar heating cir-
cuit is free of air pockets that may inter-
fere with proper operation of the pump.
The hot water is stored in the
heat
storage tank
until it is ready to be
used. The size of the storage tank
should be selected so that it is able to
supply enough water to last through
short periods of bad weather . The up-
per part of the storage tank has provi-
sions to be heated by some other
source, if necessary, to ensure that hot
water will also be available during bad
weather conditions . Solar energy is the
sole source of heat for the lower part of
the tank.
The
expansion tank
is used to com-
pensate for the temperature-related
expansion and contraction of the heat
transfer fluid. The tank is sized to pre-
vent venting of the heat transfer fluid
via the safety valve, even if the fluid
vapourises. This can occur when not
enough heat is being removed from the
collector because the pump is off.
A
mounting rack
is used to facilitate
installation of the collectors. Various
suitably designed roof mounting sys-
tems are available for different types of
roofs.
The heat transfer fluid,
which is
pumped through the solar circuit using
the
solar pump
, transfers the heat
from the collectors to the storage tank,
where it is transferred to the domestic
water system via a heat exchanger.
The heat transfer fluid has anti-freeze
in it so that the system does not freeze
and incur damage during the winter.
The non-toxic and physiologically harm-
less heat transfer fluid is designed to
accommodate the extreme temperature
swings from – 30°C to over 200°C .
