Cooling circuit
The VCCS is selected on only when the GASC receives a cooling request. It
is composed of two independent circuits :
-- one for the cockpit zone
-- one for the cabin zone
For each circuit, air is sucked by means of a variable speed electrical fan and
then blown through an evaporator and ducted to the different zones :
-- cockpit circuit, by passing through :
. the upper panel equipped with swivelling and adjustable air outlets,
. air outlets located on arm rests of pilot and R.H. side front passenger
stations and
. ports located under instrument panel.
-- cabin circuit, by passing through :
. the overhead duct equipped with swivelling and adjustable air outlets,
. ports located on the floor between the cabinets and the intermediate
passenger’s seats.
System operation
See Figure 7.9.3 and paragraph Air temperature management.
ECS control panel selection :
If the AIR COND switch is set to OFF :
Before GASC software evolution (Pre--MOD70--0689--21)
-- Temperature is set by default by the GASC to 23 ° C,
After GASC software evolution (Post--MOD70--0689--21)
-- The system maintains the cabin air inlet temperature previously selected.
The pilot can modulate this temperature by using the CABIN TEMP/ ° C
selector on ECS panel,
All
-- Cockpit / Cabin evaporator fans are OFF,
-- VCCS is inhibited.
If the AIR COND switch is set to AUTO :
-- Temperature of each zone is controlled by the GASC, using inputs from
both CABIN TEMP/ ° C selectors and temperature sensors for reference,
-- Fan speed is controlled by the GASC.
