Climate Control (12.00)
Body Ventilation (12.01)
Air Intake & Distribution System
Outside air enters the plenum via inlets at the base of the
windscreen.
Fresh mode - Air is drawn in through the plenum and into
the blower unit. From the blower unit air enters the A/C unit
where it is cooled and dehumidified as it passes through the
evaporator. It is then ‘reheated’ to the selected temperature
as it passes through the heater matrix,. Air flows from the cabin into th
e boot via air vent grilles and
through apertures in the rear parcel shelf. The air is
exhausted from the vehicle through extraction vent
assemblies (incorporating one way flaps) in the lower part of
the rear bumpers, concealed by the bumper trim.
Recirculation mode - The air in the passenger
compartment is drawn into the A/C system via the re-
circulation air inlets on the blower unit.
The A/C unit is linked and sealed to the defrost / demisting and cabin air ducting assemblies. The A/C unit incorporates
two actuator operated flaps which regulate airflow to the selected air flow mode and temperature blend.
The centre vent duct incorporates a baffle plate which balances the volume of airflow of the centre and end of dash vents.
