The present invention relates to a vehicular air conditioning system and provides a vehicular air conditioning system capable of preventing overheating of an inverter that controls the rotation speed of an electric compressor without cutting off the inverter, and consequently preventing the stoppage of an air conditioner due to the cut-off of the inverter and the resultant stoppage of cooling of a passenger room. The vehicular air conditioning system includes an electric compressor, an inverter configured to control a rotation speed of the electric compressor, and a control part configured to execute control so that a refrigerant flow rate on an inlet side of the electric compressor increases when a temperature of the inverter is equal to or higher than a preset overheating warning temperature.
