Abstract
A main duct (12) contains a heater (19) and has an upper air outlet (22). A bypass duct (31) has an inlet (32) communicating with the main duct (12) upstream of the heater (19) and an outlet (33) communicating with the upper air outlet (22). A humidifier (36) is provided in the bypass duct (31). The bypass duct (31) has a circulated air inlet (37) and a proportioning door (38) for controlling the amount of air entering the bypass duct (31) from the main duct (12) and the circulated air inlet (37) to enable temperature control of the humidified air which is discharged from the upper air outlet (22) against the driver's face. An air cleaner (71) may also be provided in the bypass duct (31) and operated with the humidifier (36).
