Air Conditioning Unit

Air Conditioning Unit






The air conditioning unit houses the evaporator, heater matrix and their temperature sensors. The unit also incorporates two servo motor operated air distribution flaps which regulate airflow to the front footwells and the quantity of airflow through the cool air bypass (air which by-passes heater matrix) up to the upper air distribution box (ADB)

When the front footwell flap is open, air is ducted to the footwell area via the lower air distribution duct(LADD) and front footwell duct. The LADD is clipped to the bottom of the air conditioning unit case and the front foot ducts clipped onto the outlets of the LADD.

Condensate (water) which forms on the evaporator fins is drained out of the unit case through two drains located either side of the unit underneath the evaporator The liquid is routed to the vehicle exterior via flexible tubes which are located behind the firewall heatshield.
