ABSTRACT:
A vehicle air conditioning system equipped with a refrigerant circuit comprising an electrically operated compressor is intended to enable simplification of data communication between the inside and outside of a passenger compartment and to enable accurate air conditioning control. In summary, the air conditioning system is equipped with the refrigerant circuit which includes the electrically operated compressor, a gas cooler, an expansion valve, an evaporator and the like that are sequentially pipe-connected in a circular form, in which compression and heat release of a refrigerant are performed by the electrically operated compressor and the gas cooler provided outside a passenger compartment and in which the passenger compartment is cooled by the evaporator provided inside the passenger compartment, and the air conditioning system comprises: an inverter for frequency control of an operation of the electrically operated compressor; and an air conditioning amplifier to which a predetermined operation input is performed and to which information regarding the inside of the passenger compartment is input, wherein the inverter calculates an operating frequency of the electrically operated compressor on the basis of the information from the air conditioning amplifier to operate the electrically operated compressor.
