A vehicle air conditioning apparatus includes an outdoor expansion valve controller configured to control an evaporating temperature of a refrigerant in a heat exchanger by regulating an opening of an outdoor expansion valve during a heating and dehumidifying operation, an evaporating temperature control valve provided in a refrigerant flow passage to an output side of the heat exchanger from which the refrigerant is discharged, and configured to control the evaporating temperature of the refrigerant in the heat exchanger by regulating an amount of the refrigerant flowing through the refrigerant flow passage, a temperature detector configured to detect a temperature of the refrigerant in the heat exchanger, and a control changer configured to change control of the evaporating temperature of the refrigerant in the heat exchanger from by regulating an opening of the outdoor expansion valve to by regulating an opening of the evaporating temperature control valve.
