AIR CONDITIONER FOR VEHICLE

PROBLEM TO BE SOLVED: To reduce a discomfort to an occupant at a driver seat due to cool air at the initial period of blowing.SOLUTION: When the cooling water temperature Tw of a traveling engine is lower than a threshold value TW3, the cool air exhaust control (a step S105) is performed. Thus, the cool air staying in an area from an electric heater 80 in an air conditioning case 20 to a branch part of a foot ventilation passage 120 and a knee ventilation passage 130 is discharged to feet of an occupant at a driver seat from an outlet 120a of the foot ventilation passage 120. After that, when the cooling water temperature Tw of the traveling engine becomes higher than the threshold value TW3, the electric heater knee air conditioning air blowing control is performed. Thus, the air conditioning air heated by a heater core 60 and the electric heater 80 in a lower passage 22 is blown off from an outlet 130a of the knee ventilation passage 130 to the knees of the occupant at a driver seat. Thus, at starting, immediately the occupant can be made to feel warm.
