VEHICLE AIR-CONDITIONING DEVICE

An exterior heat exchanger 33 is provided with paths P1-P4. The flow rate of the air being blown by an exterior blower to pass through the path P4 closer to a refrigerant outlet of the exterior heat exchanger 33 is set to be higher than that of the air being blown by the exterior blower to pass through the path P1 closer to a refrigerant inlet of the exterior heat exchanger 33. An air-conditioning controller 22 activates cooling fans 37a and 38a during a defrosting mode of operation.
