Principle of operation:
VAV – Ventilation / Air Quality

The system makes it possible to precisely adapt the fresh air flow according to a CO2 measurement (proportional) or a presence detector (all or little).
Depending on the output signal, the flow rate adjusts between precisely set minimum and maximum values.
A differential pressure regulator is used to detect pressure changes in the duct and to adjust the position of the damper so that the set flow rate is maintained.
Pressure fluctuations therefore have no effect on the air quality of the room.

VAV – Heating / Air Conditioning

The heat input is ensured in whole or in part by the air vector.
The system makes it possible to precisely adapt the air flow between a minimum and a maximum according to the load thanks to a regulation in cascade.
A room thermostat (regulator) sends a signal C representative of the difference setpoint B / temperature measurement A to the regulator of the servomotor to deliver the necessary flow.
A differential pressure regulator makes it possible to detect changes in pressure in duct D and to adjust the position of the flap so that the set flow rate E is maintained.
Pressure fluctuations therefore have no effect on the room temperature.
