Abstract
In an automotive air-conditioning system, when pollen mode control is effected by a vehicle occupant, air outlet mode is forcibly set to a face mode. Further, the air flow amount determined from the air flow amount Vm used in the usual auto mode and the air flow amount f(Tw) used during warm-up control or the air flow amount determined by the air flow amount correction value f(Tam) having a relatively small upper limit value when ambient temperature is higher than a predetermined temperature (15° C.), whichever is larger, is taken as the set value for the air flow amount in the pollen mode control. With this arrangement, when coolant temperature and ambient temperature are low, a relatively small amount of air can be blown to the upper part of the occupant's body, and thus, while maintaining the pollen removal effect, occupant discomfort can be reduced by preventing a fast flow of air from being blown toward the occupant's face, etc.
