[Solution] This air conditioning device for a vehicle is provided with: a refrigerant circuit including a compressor, an indoor heat exchanger, and an external heat exchanger; an air conditioning unit in which the indoor heat exchanger is disposed, and which includes a blower for blowing air, after heat exchange with the indoor heat exchanger, to flow into a vehicle cabin; and a control device for controlling the refrigerant circuit and the air conditioning unit. The refrigerant circuit has a hot gas bypass which decompresses at least a portion of the refrigerant compressed by the compressor without passing through the external heat exchanger and returns the portion of the refrigerant to the compressor. The control device is capable of performing control to execute a hot gas heating operation in which the heat of the refrigerant compressed by the compressor is radiated in the indoor heat exchanger and heats the inside of the vehicle cabin, without causing the refrigerant to absorb heat in the external heat exchanger. In the case where the air temperature after heat exchange in the indoor heat exchanger is determined to be equal to or less than a predetermined temperature during the execution of the hot gas heating operation, a restriction mode for lowering the upper limit value of the air volume by the blower is set.
[Problem] The problem of the present invention is to prevent vent temperature from dropping when a target air temperature is raised during hot gas heating operation.
