Abstract

The turbo compressor includes a drive shaft (3); an impeller (7.1) connected to an first axial end portion of the drive shaft (3); an electrical motor connected to a second axial end portion of the drive shaft (3); an axial bearing arrangement configured to limit an axial movement of the drive shaft (3) during operation, the axial bearing arrangement including an axial bearing plate (18) having an annular ring shape and facing towards the impeller (7.1); an inlet distributor (33) at least partially defining an inlet refrigerant flow path (P) ; and an axial bearing cooling arrangement including bypass openings (40) formed in the inlet distributor (33) and a bypass refrigerant flow path (43) defined by the inlet distributor (33) and the axial bearing plate (18), the bypass openings (40) being configured to derive a part of an inlet refrigerant flow, flowing into the inlet refrigerant flow path (P), into the bypass refrigerant flow path (43) so as to at least partially cool the axial bearing plate (18).
