An air conditioning system for use with an automotive vehicle is disclosed. The air conditioning system includes a duct through which tempered air is directed into a compartment for passengers. A control device is associated with the duct for operating in a first mode discharging the tempered air in the form of concentrated currents toward the respective passengers, in a second mode discharging the tempered air in the form of diffused currents toward the respective passengers, and in a third mode changing the first and second modes at variable time intervals. One of the first, second and third modes is selected according to sensed values of compartment temperature and insolation intensity. The ratio of a first time period during which the first mode is continued in the third mode to a second time period during which the second mode is continued in the third mode is increased with increasing insolation intensity.
