7.9 -- AIR CONDITIONING AND PRESSURIZATION
AIR CONDITIONING (Figure 7.9.1)
Air conditioning system includes the temperature and flow--pressure
regulation system (ACS), the vapor cycle cooling system (VCCS), control
and check systems and distribution.
Temperature and flow--pressure regulation system
Air necessary for conditioning is picked up from the engine. A valve regulates
pressure and bleed hot air flow and is also used as shutoff valve. This valve is
controlled by the ”BLEED” switch. Hot air is cooled by going through a
temperature exchanger and a cooling turbine, then it reduces the humidity
through the water separator before entering the cabin through a
check--valve.
Temperature exchanger is located in a duct which directs cooling air. This air
is picked up outside by the NACA scoop located on R.H. FWD engine
cowling. When the airplane is on ground, air flow is created by the cooling
turbine driven by air picked up from the engine.
Temperature regulation is accomplished by adding hot air to the air coming
from cooling turbine. An electronic control unit analyses the temperature of
conditioned air, as it enters the cabin, as well as cabin ambient temperature
and acts on the temperature regulation valve according to the requested
temperature.
