Claim:
1. An automotive air conditioning system comprising: an air cooling circuit including a compressor, a condenser, an expansion valve and an evaporator, fluidically connected to be flowed through, during operation, by a first heat transfer fluid, and a blower fan associated with the evaporator and operable to generate an airflow through the evaporator; an air heating circuit including a heater configured to be flowed through, during operation, by a second heat transfer fluid, and arranged close to the evaporator to be also flowed through by the airflow generated by the blower fan associated with the evaporator, and a flow rate regulation solenoid valve arranged to regulate the flow rate of the second heat transfer fluid through the heater; and an electronic control unit configured to receive a measured evaporator air temperature and a set cabin air temperature and to switch an operating condition of the compressor when the measured evaporator air temperature is higher or lower than at least one on/off threshold temperature computed based on the set cabin air temperature, wherein the electronic control unit is further configured to:
