GENERAL - SYSTEM PRESENTATION
The air conditioning system maintains the air in the
pressurized fuselage zones at the correct levels of
temperature, freshness and pressure
INTRODUCTION
Air supply comes from the pneumatic system.
Then, air is regulated in temperature by the
temperature regulation sub-system.
Proper ventilation of the avionics equipment is
ensured by the avionics ventilation sub-system.
The pressurization sub-system ensures a cabin altitude
compatible with crew and passenger comfort.
