Vehicle air conditioning system

A vehicle air conditioning system equipped with a refrigerant circuit comprising an electrically operated compressor (18) is intended to enable simplification of data communication between the inside and outside of a passenger compartment. The air conditioning system is equipped with an electrically operated compressor (18), a gas cooler (19), an expansion valve (21), an evaporator (6), an inverter (22) for frequency control of an operation of the electrically operated compressor; and an air conditioning control unit (13) to which an operation input is performed and to which information regarding the inside of the passenger compartment is input. The inverter is located outside the passenger compartment.
