1. A compressor assembly comprising:
centrifugal compressors arranged in sequence, wherein each centrifugal compressor includes a rotor and a drive shaft, wherein the rotor is configured to rotate in a rotor plane and about the drive shaft extending perpendicular to the rotor plane; a housing for the centrifugal compressors, the housing includes an inlet and an outlet, wherein the inlet is arranged such that air flows through the inlet into the housing in an inflow direction extending parallel to the drive shaft, and the outlet is arranged such that air flows out of the outlet in an outflow direction extending in the rotor plane, and the centrifugal compressors are arranged such that air flowing into the inlet of one of the centrifugal compressors arranged foremost in a flow direction flows in succession in the flow direction, through the remaining ones of the centrifugal compressors and wherein the air flowing out of the outlet of an upstream one of the centrifugal compressors flows directly into the inlet of a downstream one of the centrifugal compressors; the drive shafts of two in the flow direction directly successive centrifugal compressors of the plurality of centrifugal compressors are arranged at an angle of between 0 degrees and 90 degrees with respect to one another, and in that the outflow direction of one centrifugal compressor of the plurality of centrifugal compressors and the inflow direction of a directly downstream centrifugal compressor of the plurality of centrifugal compressors are arranged at an angle of between 0 degrees and 90 degrees with respect to one another such that air flowing out of the outlet in the outflow direction need be redirected by at most 90 degrees in order to be able to flow in the inflow direction into the inlet of the directly downstream centrifugal compressor. |
