[Object] To prevent cool defrosting when heating startup control is performed in a vehicle air conditioner having upper and lower two layers. [Solution] An upper (lower) temperature adjusting door (30A, 30B) is provided in an upper (lower) air blowing path (12A, 12B) between a cooling heat exchanger (26) and a heating heat exchanger (28) and adjusts a first (second) bypass ratio that is the ratio of the volume of the air passing through an upper (lower) bypass channel to the volume of the air flowing out of an upper (lower) part of the cooling heat exchanger. When heating startup control is performed, the upper and lower temperature adjusting doors are positioned so that both the first bypass ratio and the second bypass ratio become substantially zero and a defroster door (32D) is controlled so that the air flowing through a mixing chamber can pass through a defroster blowout passage (32). After that, when the temperature of conditioned air to be supplied to a vehicle cabin is lowered gradually as the temperature in the vehicle cabin rises, the upper and lower temperature adjusting doors are controlled so that the second bypass ratio increases earlier than the first bypass ratio.
