3023550 - E6020 AIR CONDITIONING - Description (Condizionatore automatico)
Description
An automatic system manages the passenger compartment climate control, i.e. temperature and ventilation with recirculation and air flow orientation, with separate management of the temperature for the left and right hand sides of the passenger compartment.A dedicated control unit manages system operation by controlling:
- air temperature at the driver/passenger vent;
- Air distribution to the vents.
- fan speed (varies continuously);
- activation of the compressor (air cooling circuit);
- activation of air recirculation;
- the MAX-DEF fast defrost function (i.e. a set of actions which allow both the windscreen and the rearscreen to be demisted quickly);
The following parameters/functions can be modified manually:
- fan speed;
- distribution direction;
- compressor disablement;
- defrosting/demisting:
- recirculation.
The control unit downloads information on interior and exterior temperature and climatic conditions via special sensors.
- exterior temperature sensor, locate on the driver's side door mirror. The sensor reading is downloaded by a control unit on the door and filtered as necessary; it is then sent via the CAN network to the climate control system ECU (to instrument panel and other appliances).
- lower mixed air temperature sensor (right and left);
- upper mixed air sensors (right and left);
- passenger compartment temperature sensor;
- sunlight sensor, which measures the sun's rays on the windscreen;
- exhaust gas presence sensor (A.Q.S.: Air Quality Sensor):supplies a signal when the air pollution index exceeds a preset level of harmfulness. This signal turns on the recirculation to prevent polluted air entering the passenger compartment;
- demisting sensor, which detects the presence of water droplets (mist) on the inner surface of the windscreen; this information turns on the relevant demisting strategy., which alters the air and ventilation distribution pattern.
