Claim 0:
1. A compressor system, comprising:
a compressor having:
an upstream region into which a working fluid flows,
a downstream region that communicates with the upstream region and in which a pressure of the working fluid is greater than that in the upstream region,
inlet guide vanes that are provided further upstream than the upstream region and are capable of altering a flow rate of the working fluid flowing into the upstream region, and
an extraction part that is provided to a portion between the upstream region and the downstream region and is capable of extracting at least a portion of the working fluid;
detection devices, at least one of which is provided in each of the upstream region and the downstream region, for detecting a physical quantity of the working fluid; and
a control device for adjusting, on the basis of changes in the physical quantity detected by the detection devices, an opening degree of the inlet guide vanes and an amount extracted by the extraction part,
wherein the physical quantity includes a flow direction and a flow velocity of the working fluid based on a temperature of the working fluid.
