Abstract:
A multi-stage compressor system is a system of a multi-stage compressor in which compressors are connected in series in a plurality of stages includes a control unit. The control unit determines whether a malfunction is present in the system by comparing a suction flow rate of a first-stage compressor measured by a first sensor with a downstream flow rate from an outlet of the multi-stage compressor measured by a second sensor.
