Cooling Packs (Cont’d)
The cooling packs are shutoff (FCV closed) under the following circumstances:
.
In AUTO operation, by the ACSC acting on the FCV torque motor due to:
.
Bleed failure or shutdown (on BMC demand).
.
Engine starting (on BMC demand).
.
During ditching operation, if airplane is below 15,000 feet.
.
Pack inlet overheat.
.
Compressor discharge overheat.
.
Pack discharge overheat.
.
Pack discharge underpressure.
Full closed position to ACSC
Torque motor control from ACSC

. In AUTO or MANUAL operation, by the compressor pneumatic overheat sensor (CPNOH), acting pneumatically on the FCV actuator due to compressor discharge overheat or by crew selection of the PACK switch, acting on the FCV solenoid.
FCV ON/OFF solenoid command from L or R PACK switch

AIR CONDITIONING AND PRESSURIZATION
Flow Control System
The flow control system regulates airflow from the pneumatic duct to the air conditioning units.
The flow control system interfaces with:
.
Bleed Air System . The flow control system takes bleed air from the engine, the APU, or a ground source and provides filtered air into the air conditioning units.
.
Air Conditioning System Controllers (ACSC) which measure, calculate and control the airflow.
.
Air Conditioning Units (packs) which use the filtered air supply.
A flow control valve (FCV) will modulate to meet a preset flow schedule and is normally controlled by the Air Conditioning System Controller (ACSC).
When an overheat is detected, the ACSC will automatically close the FCV and display the affected caution message on EICAS.
