Abstract

PURPOSE: To perform a surging prediction with high accuracy by providing an arithmetic processor for calculating a power changing ratio or a power equivalent amount changing ratio and also providing a controller for controlling the operational condition of a compressor.
CONSTITUTION: An arithmetic processor 23 is provided for calculating a power changing ratio against a pressure ratio or suction flow rate at a revolutional number corrected by a constant, and a power equivalent amount changing ratio against a pressure ratio or suction flow rate at a revolutional number corrected by a constant with use of the outputs of respective detectors 17W22. A controller 25 for controlling the operational condition of a compressor 16 in such a way that at least one of the power changing ratio and the power equivalent amount changing ratio cannot exceed a limited value. Therefore, it is possible to perform the surging prediction with high accuracy.
