An air conditioning device for a vehicle has a compressor, an evaporator, a driving condition detector, a temperature detector, and a controller. The driving condition detector detects a driving condition of the vehicle. The evaporator has a cold storage portion storing the heat from the refrigerant and having phase-change energy in at least two different temperature ranges. The controller (i) maintains the compressor being stopped while a temperature detected by the temperature detector is lower than or equal to the first temperature when the vehicle is in a coasting operation and (ii) maintains the compressor being stopped while the temperature is lower than or equal to the second temperature when the vehicle is stopped. The coasting operation is a driving condition in which a vehicle speed is lower than or equal to a specified speed and an acceleration device of the vehicle is not operated.
