PROBLEM TO BE SOLVED: To provide a vehicular air conditioning system reduced in the amount of refrigerant filled in the system, improved in installability on a vehicle, and reduced in costs by eliminating a receiver. SOLUTION: In this vehicular air conditioning system 1, a compressor 2 for compressing refrigerant, a condenser 3 for liquefying the refrigerant flowing from the compressor 2 by condensing, a pressure reducing means 7 for reducing the pressure of the refrigerant sent from the condenser 3 and an evaporator 8 for evaporating the refrigerant supplied from the pressure reducing means 7 are connected in this order by a refrigerant pipe 9 to structure a refrigerant circuit 10, and the refrigerant circuit 10 is filled with a predetermined quantity of the refrigerant. A heat exchanger tube 3C arranged in a lower part of the condenser 3 works as a reservoir part 3F for the condensed refrigerant, and a certain quantity of the refrigerant having condensate depression of 5-10°C stored in the reservoir part 3F is filled in the refrigerant circuit 10.
