Abstract
An inverter is disposed at a position on the upstream side relative to a compression mechanism along the flow of a refrigerant and the position cooled by the refrigerant. A motor is disposed at a position heated by the refrigerant compressed by the compression mechanism. A control device changes an upper limit value of a driving current supplied to the motor on the basis of at least one of first information relating to the temperature of the motor or second information relating to the temperature of the inverter.
