5. How to dimension the EvoFlat system?
System design and dimensioning principles
Dimensioning
A careful calculation of the pipe system
and a precise configuration of the
required dimensions are main requirements
for an energy efficient operation
of every system. In this respect systems
with flat stations are no different to
conventional systems, even though a
complete hydraulic balanced complete
system can be implemented considerably
easier with the use of flat stations.
Elements of the system dimensioning
