F5.07 Complete AC unit
The A.C. system must be capable of supplying the passenger compartment with air at the desired
temperature via the outlet vents listed below, regardless of any external disruption such as intense
sunlight, vehicle speed or the air distribution mode:
air vents (right, centre right, centre left and left);
footwell air vents (right and left);
defrosting vents (right and left).
The temperature of the air coming out of the vents may be regulated independently and separately on the
right and left sides of the HVAC cluster, and between equivalent vents.
In a single vent, the difference in temperature between the hottest and the coldest points should not exceed 3
°C . This requires a homogenous mixture in each vent.
The maximum disparity between the upper left and upper right vents, for any type of distribution, is 5 °C
under single zone use.
Cooling of the air distributed by the HVAC module and the consequent dehumidification takes place thanks to
aluminium heat exchangers, which make the refrigerant fluid R134a evaporate internally, after having
reduced its pressure using the thermostatic expansion valve.
