Abstract
A compressor 1 includes a casing 2 that covers a rotating shaft 4 and an impeller 6 and is provided with a diffuser 66 for guiding the working fluid discharged from the impeller 6 to an outside in a radial direction, a heat exchanger 71 that is cools at least a portion of the working fluid compressed by the impeller 6, a cooling fluid supplying unit 7 that supplies the working fluid cooled by the heat exchanger 71 into the casing 2 as a cooling fluid for cooling a motor 5 disposed in the casing 2, and a cooling fluid circulating unit 8 that discharges the cooling fluid that has passed through the motor 5 to an outside of the casing 2, and supplies the discharged cooling fluid downstream of an outlet 6o of a first impeller 6A and upstream of the diffuser 66.
