It consists of: - Environmental Control Unit (ECU), - distribution system.
Recycled cabin air Ram air (for heat exchanger ventilation)įIGURE 02-21-05-01 AIR CONDITIONING ECU AND RAM AIR LOCATIONįIGURE 02-21-05-02 MAIN PRESSURIZATION COMPONENTS LOCATIONĭESCRIPTION INTRODUCTION The air conditioning system provides the pressurized areas with air at mild temperature. AIR CONDITIONINGĮngine No 1, 2 and 3 and/or APU bleed air Conditioned air On ground or in-flight at low speed, with additional air supplied through an air inlet located on the lower part of the fuselage.
In-flight, with external air supplied through a ram air inlet located on the No 1 engine pylon leading edge, The air conditioning heat exchanger is ventilated:. Hot bleed air directly supplied by engines HP and LP ports, or the APU,Ĭold air (hot bleed air cooled through the Environmental Control Unit (ECU)), Ø For more information, refer to CODDE 1 / Chapter 02 / ATA 36. SOURCES The air conditioning system uses air supplied by: -ĪPU. In case of failure (overpressure, negative pressure, maximum altitude), protections ensure that limitations are observed. They use hot air supplied by the engines and/or the APU.
The maximum differential pressure supported by the system.īoth systems have an automatic mode and a manual mode, allowing the pilot to control directly the valves. The pressurization system regulates the cabin pressure, by the air flow discharged outside of the cabin, it depends on:. The air conditioning system regulates the flow and temperature of air into the cabin and cockpit areas for conditioning purpose. INTRODUCTION In order to maintain a comfortable area inside the cabin, the F900EX EASy is equipped with an air conditioning and pressurization system.
