AIR CONDITIONING -DISTRIBUTION -INTRODUCTION

General
The distribution system has these parts:
*
Main air

*
Flight deck conditioned air

*
Passenger cabin conditioned air

*
Recirculation

*
Ventilation

*
Equipment cooling.


The distribution system lets conditioned and recirculated air flow from the packs and mix manifold to locations in the cabin and flight deck. The ventilation part of the system removes odors from the lavatories and galleys. The equipment cooling part of the system cools electrical and electronic equipment.
See the distribution -ventilation section for more information about the ventilation in the airplane (SECTION 21-26).
See the equipment cooling section for more information about the forward and aft equipment cooling systems (SECTION 21-27).

AIR CONDITIONING -DISTRIBUTION -GENERAL DESCRIPTION

General
The distribution system includes ducts and fans that move conditioned and recirculated air through the airplane.
Main Air Distribution
Air from the packs flow through the main air distribution ducts to these locations:
*
Flight deck distribution

*
Mix manifold.


Mix Manifold
The usual flow of air from the mix manifold goes to the passenger cabin conditioned air distribution. The mix manifold also gives air to the flight deck conditioned air distribution if the left air conditioning pack is off. See the main air distribution section for more information about the mix manifold (SECTION 21-21).
Flight Deck Conditioned Air Distribution
The flight deck distribution duct carries conditioned air from the left pack to the flight deck. See the flight deck conditioned air distribution section for more information about air distribution to the flight deck (SECTION 21-22).
Passenger Cabin Conditioned Air Distribution
Eight risers carry air from the mix manifold, below the passenger cabin floor to the overhead distribution ducts above the passenger cabin ceiling. The overhead distribution ducts carry the air to the air outlet ducts in each of the passenger zones. See the passenger cabin conditioned air distribution section for more information about air distribution to the passenger cabin (SECTION 21-23).
