The present invention is to provide an air conditioning apparatus for a vehicle which can prevent power of a battery from being consumed to perform a defrosting operation while the vehicle is travelling, and can continuously perform a heating operation even though an external heat exchanger is frosted. The air conditioning apparatus for a vehicle includes a refrigerant heater 41 that is provided between an internal evaporator 8 and a suction side of an electric compressor 20 to be in parallel with an external evaporator 32, and heats a refrigerant which is suctioned into the electric compressor 20; and an air conditioning control apparatus 50 that determines whether the external evaporator 32 is frosted. While the air conditioning apparatus for a vehicle operates in a heating mode, when the air conditioning control apparatus 50 determines that the external evaporator 32 is frosted, a supply of the refrigerant subject to the heat exchange in an internal condenser 9 to the external evaporator 32 is stopped, and the refrigerant is supplied to the refrigerant heater 41, is heated and then, is suctioned into the electric compressor 20.
