Abstract
In this container refrigerator, the permissible equivalent negative-phase-sequence current of a generator to be connected is calculated in Step Sbased on its capacitance. Next, in Step S, the power consumption of an inverter device to generate the equivalent negative-phase-sequence current is calculated. Then, in Step S, the equivalent negative-phase-sequence current generated by the container refrigerator is calculated based on the power consumption of this inverter device. Thereafter, in Step S, Iis compared to I. If I>Iis satisfied, Iis restricted until I≦Iis met by lowering the output frequency of the inverter device repeatedly in multiple stages. Consequently, even if the generator connected has small capacitance, the operation may be continued at a number of rotations appropriate for that small capacitance without causing the generator to overheat or be burned out.
