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.
