Abstract
A centrifugal compressor includes an impeller that rotates about an axis; an inlet guide vane including a plurality of vanes disposed on an upstream side of the impeller and provided at intervals in a circumferential direction of the axis, the inlet guide vane being directed inward in the radial direction between adjacent vanes, and forming a guide flow path having an exit angle in the radial direction and guiding the fluid; and a suction flow path that introduces the fluid from a part in a circumferential direction into the inlet guide vane. The exit angle of the vane of the first region on the one side when viewed from the suction flow path in the inlet guide vane is displaced to the suction flow path side as compared to the exit angle of the vane of a second region on the opposite side of the one side.
