Abstract
A centrifugal compressor includes an impeller, a return channel including a return vane for guiding a main stream of a fluid to be compressed by the impeller from an outer side of a main shaft of the impeller in a radial direction toward an inner side, stages of compressor units connected to a downstream side of the return channel and including a first bent channel for changing the main stream to a direction along the main shaft, and an intermediate suction channel connected to the return channel in at least one of the compressor units to merge a suctioned fluid to the main stream. The intermediate suction channel includes a chamber having a scroll shape and passing the suctioned fluid therethrough, and an inlet guide vane for guiding the suctioned fluid. The inlet guide vane is integrated with the return vane in the connected return channel.
