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.

Abstract: In an air-conditioner control unit, when pollen mode control is set by a vehicle occupant to perform the pollen mode control that can provide a defogging effect while maintaining the pollen removal effect, the opening of an air inlet door is forcibly set to an inside-air introduction mode (S330) when the following two conditions hold: ambient temperature Tam is higher than a threshold (5 to 6° C.) set in a low-temperature region (S320), and a compressor system is able to operate normally without causing an abnormal pressure (S330). If even one of these conditions does not hold, the opening of the air inlet door is not forcibly set to the inside-air introduction mode, and the air inlet door is operated as in normal control. In this way, in the pollen mode control, since the pollen removal effect in the inside-air introduction mode is enabled only when the ambient air is relatively high, the occurrence of windshield fogging can be suppressed.
