Operating principle
When a single system contains a primary production circuit, with its
own pump, and a secondary user circuit, with one or more
distribution pumps, operating conditions may arise in the system
whereby the pumps interact, creating abnormal variations in circuit
flow rates and pressures.
The hydronic separator creates a zone with a low pressure loss,
which enables the primary and secondary circuits connected to it to
be hydronically independent of each other; the flow in one circuit
does not create a flow in the other if the pressure loss in the
common section is negligible.
In this case, the flow rate in the respective circuits depends
exclusively on the flow rate characteristics of the pumps, preventing
reciprocal influence caused by connection in series.
Therefore, using a device with these characteristics means that the
flow in the secondary circuit only circulates when the relevant pump
is on, permitting the system to meet the specific load requirements
at that time. When the secondary pump is off, there is no circulation
in the secondary circuit; the whole flow rate produced by the
primary pump is by-passed through the separator.
With the hydronic separator, it is thus possible to have a production
circuit with a constant flow rate and a distribution circuit with a
variable flow rate; these operating conditions are typical of modern
heating and air-conditioning systems.
Three possible hydronic balance situations are shown below.
