PROBLEM TO BE SOLVED: To provide a vehicle air conditioning device configured to prevent an increase in consumption of power to be used for conditioning the air in a cabin even if an operation condition is changed.SOLUTION: An upper limit value of power to be supplied to an electric heater 42 arranged in a heat medium circuit 40 as a heating means for heating the inside of a cabin, is set by subtracting power consumed by a compressor 31 of a refrigeration cycle 30 from predetermined reference power KD. The total value of the power consumed in the compressor 31 and the power consumed in the heat medium circuit 40 can be set equal to or lower than the reference power KD, irrespective of an operation condition of a vehicle air conditioning device, thereby preventing the power to be consumed for conditioning the air in the cabin from increasing beyond the reference power KD. |
