F5.01 AC system layout
System overview
The air conditioning and heating system in the California automatically regulates the temperature and humidity
in the passenger compartment. The system can simultaneously and independently regulate air temperature
and distribution for the driver side zone and passenger side zone.
The AC system consists of a heating, ventilation and air conditioning unit (HVAC) located under the dashboard.
The passenger compartment is split longitudinally into two temperature zones:
driver zone;
passenger zone.
The dual zone regulation system regulates the following parameters:
passenger compartment air temperature in driver zone;
air distribution via vents in driver zone;
passenger compartment air temperature in passenger zone;
air distribution via vents in passenger zone;
ventilation with external air or recirculating air in passenger compartment;
fan speed.
Functional requisites
The functions of the HVAC module, located under the dashboard, consist in aspirating air through heat
exchanger either from outside the vehicle or from inside (REC function) and in continuously adjusting the
quantity and temperature of the distributed air.
The air introduced into the vehicle must be filtered to remove particulate and odours in both external air and
REC modes.
The air temperature is regulated by altering the flow of refrigerant through the heater core in two symmetrical
crossed circuits, with one on the left hand side and one on the right hand side.
