= 11,11 l (expansion volume)
A plant height of 10 m results in a size of the expansion tank
of at least V
EXPmin
= 23 l.Here an expansion tank of 25 l should
be used.
Intermediate container:

EXP min.
x 0.5 = 23 l * 0.5 = 11,5 l
Here an intermediate tank of 12 l should be used.
Basis for the table is a safety valve with a trip pressure of 6 bar, system
pressure of pstat + 0.5 bar and the expansion volume of the solar plant
installed. The expansion volume (Vd) is derived from the collector volume
(Vkoll), the volume of the connecting pipes (Vr) and the plant volume (Va)
multiplied by the coefficient of expansion (e) of the heat transfer medium.
Design of intermediate container
Intermediate tanks are to be used in all plants with very short pipe runs
and/or very small cross sections, or with large collector areas or collectors
with large volume (content of return pipework < 50% of a properly de-
signed expansion tank V
EXP
).

In order to be able to use the following table, the expansion

must be calculated: V

Basis for the calculation of the table is:
