Operating principle:
VAV – Ventilation / Air Quality

The system allows the fresh air flow to be precisely adapted based on a CO2 measurement (proportional) or a presence detector (total or partial).
Depending on the output signal, the flow rate adjusts between precisely set minimum and maximum values.
A differential pressure regulator is used to detect changes in duct pressure and adjust the position of the flap so that the set flow rate is maintained.
Pressure fluctuations therefore have no impact on the air quality in the room.

VAV – Heating / Air Conditioning

The heat supply is provided in whole or in part by the air vector.
The system allows the air flow to be precisely adapted between a minimum and a maximum depending on the load thanks to cascade regulation.
A room thermostat (regulator) sends a signal C representing the difference between setpoint B and temperature measurement A to the servomotor regulator to deliver the necessary flow rate.
A differential pressure regulator is used to detect changes in duct pressure D and to adjust the position of the flap so that the set flow rate E is maintained.
Pressure fluctuations therefore have no impact on the room temperature.
