Vehicular air conditioning apparatus for effectively cooling a main cooling unit and an additional cooling unit
 A main evaporator cools a driver's compartment of a vehicle while a cooling storage evaporator cools cooling storage packs that are used in cooling a sleeping compartment. Refrigerant is supplied to the main evaporator at the actuation of a first solenoid valve while refrigerant is supplied to the cooling storage evaporator at the actuation of a second solenoid valve. If a first switch is being actuated after the completion of the cooling storage operation of the cooling storage evaporator on the cooling storage packs and the temperature of the cooling storage packs is no more than a preset temperature, for example, -5.degree. C., FIR control is performed for alternately actuating the first solenoid valve and the second solenoid valve based on a predetermined time ratio (for example, 10 minutes 15 seconds).
