Construction and function
"Regtronic RD-W"
3.2.1 Buffer storage cylinder loading
Loading
of the
buffer storage cylinder
with as constant a loading temperature as
possible results in the following advantages:
•
optimised storage cylinder loading
•
low return temperature to the heat
generator
•
fewer burner starts
Depending on the system constellation,
distinction is made between the following to
variants of
storage cylinder loading
:
•
0-10 V activation
•
Two point activation (volt free)
3.2.2 Riser control
The supply of heat to the connected dwelling
stations according to requirements is
guaranteed by the
riser control
. The actual
temperatures in the supply and return pipe
are constantly detected by two
sensors
(4)
and are transmitted to the
controller (1)
which activates the
motor-operated mixing
valve (2)
on this basis.
If, for instance, the temperature in the return
pipe of the riser drops significantly as water
is drawn off at several draw off points in
parallel, the
mixing valve (2)
will be fully
opened temporarily, i.e. colder return water
will no longer be added to the supply
pipe in order not to undercut its required
minimum temperature. An excessive flow
temperature is avoided by adding return
water to the supply pipe.
The current
differential pressure
is
detected by another
sensor (5)
. If the
differential pressure in the return pipe drops
quickly, an immediate correction leading to
a short-term increase of the flow pressure
during an adjustable period will be carried
out by the
riser pump (3)
.
