B737-700 Air Distribution
Conditioned air for the cabin comes from either the airplane air
conditioning system or a preconditioned ground source. Air
from the preconditioned ground source enters the air
conditioning system through the mix manifold.
The air conditioning system provides temperature controlled air
by processing bleed air from the engines, APU, or a ground air
source in air conditioning packs. Conditioned air from the left
pack, upstream of the mix manifold, flows directly to the flight
deck. Excess air from the left pack, air from the right pack, and
air from the recirculation system is combined in the mix
manifold. The mixed air is then distributed through the left and
right sidewall risers to the passenger cabin.
