conditioned air. This provides a constant supply of fresh air
circulation. Controls in the flight compartment permit selection
of temperature and flow rates.
Passenger Cabin Conditioned Air Distribution
The passenger compartment has two zones for independently
controlled air temperature. There are supply ducts that supply a
constant flow to all areas. In each zone, the conditioned air goes
to these areas:
* Passenger cabin
* Lavatories
* Galleys.
Recirculation System
The recirculation system permits ventilation of air in the
passenger cabin areas. The recirculation system decreases
the use of engine bleed air. This enables better thrust
management and decreases fuel consumption.
Ventilation System
Vent ports adjacent to the lavatory and galleys let air in those
areas flow overboard.
Equipment Cooling
The equipment cooling system uses fans to move air around
equipment in the EE compartment and flight compartment.

General
The A/C distribution system supplies conditioned air to the
passenger and flight compartments.
Main Air Distribution
The main air distribution system gets air from these sources:
* Air conditioning packs
* Ground conditioned air
* Recirculation system.
The mix manifold collects and mixes air from any combination
of the sources.
Flight Compartment Distribution
The flight compartment gets conditioned air from the left pack
and the mix manifold. A duct on the left side of the airplane
transmits the air. The flight compartment has supply ducts and
outlets to control the air flow at each station.
Passenger Compartment Distribution
The passenger conditioned air distribution gets air from the mix
manifold. The air goes through riser ducts and up side walls to
an overhead distribution duct. Outlets along the side walls and
the center of the ceiling divide the air for symmetrical supply.
Recirculation System
The recirculation system uses two fans to move air from the
passenger compartment to the mix manifold. This system
reduces the amount of air that the packs need to supply.
Ventilation
The ventilation system uses differential pressure to pull air out
of the airplane. The air moves through overboard vents from the
cabin galley and the lavatory areas.
Equipment Cooling System
The equipment cooling system removes heat from the
equipment in the main equipment center and the flight
compartment.

General
The controls for the air conditioning distribution system are on
the air conditioning/bleed air controls panel in the flight
compartment.
Recirculation System
The recirculation fans are enabled when you move the
recirculation fan switches to the AUTO position. Recirculation
fan operation depends on air conditioning pack operation.
