Water flow-rate
The design water flow-rate must be:
inside the exchanger operating limits
guaranteed also with variable system conditions (for example,
in systems where some circuits are bypassed in particular
situations)
If the system capacity is below the minimum flow, bypass the
system as indicated in the diagram.
If the system capacity exceeds the miaximum flow, bypass the
system as indicated in the diagram
Admissible water flow-rate
Minimum (Qmin) and maximum (Qmax) admissible water flow for
the unit to operate correctly.
Minimum water flow
Maximum water flow
