A turbo compressor including: - a drive shaft having a longitudinal axis and including a first axial end portion and a second axial end portion opposite to the first axial end portion, - a compression stage configured to compress a refrigerant, the compression stage including an impeller (7.1) connected to the first axial end portion of the drive shaft, - an electrical motor connected to the second axial end portion of the drive shaft and configured to drive in rotation the drive shaft about a rotation axis, - an axial bearing arrangement configured to limit an axial movement of the drive shaft during operation, the axial bearing arrangement including: o an axial bearing plate having an annular ring shape and facing towards the impeller (7.1), o an additional axial bearing plate having an annular ring shape, o a spacer ring being clamped between the axial bearing plate and the additional axial bearing plate at radial outer portions of the axial bearing plate and the additional axial bearing plate, the spacer ring defining an axial distance between the axial bearing plate and the additional axial bearing plate, o an axial bearing member arranged on the outer surface of the drive shaft, the axial bearing member extending substantially radially outwardly with respect to the drive shaft and extending into a space between radial inner portions of the axial bearing plate and the additional axial bearing plate, - an inlet distributor at least partially defining an inlet refrigerant flow path configured to supply the compression stage with an inlet refrigerant flow, the inlet distributor being located adjacent the axial bearing plate, characterized in that the turbo compressor further includes an axial bearing cooling arrangement configured to cool at least partially the axial bearing plate, the axial bearing cooling arrangement including bypass openings formed in the inlet distributor and a bypass refrigerant flow path defined by the inlet distributor and the axial bearing plate, the bypass refrigerant flow path extending at least partially along a surface of the axial bearing plate facing towards the inlet distributor, the bypass openings being configured to derive a part of the inlet refrigerant flow into the bypass refrigerant flow path such that said derived part of the inlet refrigerant flow at least partially cools the axial bearing plate, the bypass refrigerant flow path being fluidly connected to the inlet refrigerant flow path downstream of the bypass openings such that the derived part of the inlet refrigerant flow returns to the inlet refrigerant flow after having at least partially cooled the axial bearing plate. -
