Information regarding the system hydraulics
•
The collectors can be operated with a high specific flow rate (so-called
High-Flow). A dvantages: The collector is well cooled = high collector efficiency
level, low heat losses at the flow line. Disadvantages: High pressure drop
= powerful pump, large pipe cross-sections.
•
The collectors can be operated with a low specific flow rate (so-called
Low-Flow). Here, the advantages and disadvantages are reversed compared
to the High-Flow operation. An additional advantage, due to the higher flow
temperature, is the effective operation of a stratification cylinder.
Flow data: High-Flow (90 l/h x coll), ANRO 30 °C
