B737-700 Air Conditioning Packs
Two Air Conditioning Packs provide conditioned air from the main bleed air ducts for
pressurization and temperature control. Bleed air enters the packs through the Pack Valves.
Conditioned air is collected in the mix manifold.
A temperature sensor will activate the respective
PACK TRIP OFF light and close the Pack Valve if
temperature exceeds the value of a bleed trip.
Additional sensors are located in the ducts leading
from the Mix Manifold.

Air Systems SGR
The flow of bleed air from the main bleed air
duct through each air conditioning pack is
controlled by the respective pack valve. Normally
the left pack uses bleed air from engine No. 1
and the right pack uses bleed air from engine
No. 2. A single pack is capable of maintaining
pressurization and acceptable temperatures
throughout the airplane up to the maximum
certified ceiling. The APU is capable of supplying
bleed air for two packs on the ground, or one
pack in flight. Most external air carts are capable
of supplying adequate bleed air for two pack
operation. Do not operate more than one pack
from one engine at any time.

The temperature of the air isdirectly related to
the setting of the CONT CABIN and PASS CABIN
temperature selectors.
