This electric compressor control device comprises: a control unit of an inverter which controls a motor that drives a compressor; a physical quantity calculation unit which calculates, on the basis of one or a plurality of predetermined detection values acquired from the inverter, a physical quantity that varies depending on a workload of the compressor; a number-of-revolutions acquisition unit which acquires the number of revolutions of the motor; a storage unit which stores information representing a first threshold that varies depending on the number of revolutions of the motor, and defines whether or not the physical quantity is a normal value; and a refrigerant abnormality determination unit which determines whether or not there is an abnormality in a refrigerant system by comparing the calculated physical quantity with the first threshold, depending on the acquired number of revolutions.
