A vehicle air conditioning apparatus includes: a refrigerant circuit including a compressor; a vehicle compartment air conditioning unit including a heat exchanger configured to perform a heat exchange between the-refrigerant and air to be supplied to a vehicle compartment, and an indoor and outdoor air switching device configured to switch a percentage of indoor air or outdoor air introduced into an air flow path of the air subjected to the heat exchange in the heat exchanger; and a controller configured to control the refrigerant circuit and the indoor and outdoor air switching device. The controller is configured to be able to selectively perform operation modes having identical air conditioning purposes and having different refrigerant flow paths of the refrigerant circuit, reduces the number of rotations of the compressor, and switches the indoor and outdoor air switching device to the indoor air circulation, when switching an operation mode.
