  • Patent number: 11642934
    Abstract: A vehicle air conditioner is disclosed. The present invention provides the vehicle air conditioner, which: can directly control the amount of air passing through an evaporator and a heater core since a blower is disposed between the evaporator and the heater core; has front and rear seat discharge units respectively having heater cores, thereby having a simple form, minimizing energy consumption, and independently enabling four or more zones, including front and rear seats, the left and right of the front seats, and the left and right of the rear seats, to be air-conditioned; and can discharge an offensive smell to the outside during initial driving of a vehicle since the air outside a vehicle, flowing in from an air inlet, and indoor air flowing in from an inside air suction port, disposed at the center of the vehicle, are discharged to the outside of the vehicle by means of a second blower, and not by a front seat blower, for discharging the air to the rear seats.
