There is provided a vehicle air conditioning apparatus being capable of cooling, heating, and dehumidifying the vehicle compartment. A communication path is formed to allow communication between part of the first ventilation flue downstream of the heat absorbing unit in an air flow direction and part of the second ventilation flue upstream of the heat releasing unit in the air flow direction. The communication path is opened and closed by a communication path opening and closing damper. By this means, it is possible to perform the dehumidifying operation by opening the communication path without need of devices such as a dedicated outdoor heat exchanger, and a solenoid valve and a four-way valve to switch the refrigerant flow path in the refrigerant circuit.
