Abstract: 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, during operation, by a 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 liquid/air heater configured to be flowed, during operation, by a heat transfer fluid and arranged close to the evaporator to be flowed also 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 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 exhibits a given relation with at least one on/off threshold temperature computed, in at least certain operating conditions, based on the set cabin air temperature.

Abstract: An automotive air conditioning system comprising: an air cooling circuit including a compressor, a condenser, an expansion valve and an evaporator; an air heating circuit, including a flow rate regulation solenoid valve arranged to regulate the flow rate of a heat transfer fluid through the heater; and an electronic control unit. The electronic control unit is configured to receive a measured evaporator air temperature and a set cabin air temperature and to switch the 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.
