Abstract: In a vehicle air conditioner, a controller is configured (i) to set a target cooling temperature of air cooled by a cooling heat exchanger, (ii) to control an operation of a compressor based on a cooling temperature and the target cooling temperature of the cooling heat exchanger, and (iii) to determine a traveling state of the vehicle. The controller is configured to set a normal target temperature as the target cooling temperature when the vehicle is traveling with a normal condition, and to set a modified target temperature higher than the normal target temperature as the target cooling temperature when the vehicle starts decelerating. In addition, the controller is configured to cause the compressor to stop operating when the vehicle starts decelerating, and to cause the compressor to restart operating when the cooling temperature detected by a temperature sensor is equal to or higher than the modified target temperature.
