A refrigerating apparatus, including a turbo compressor including a driving motor and a plurality of bearing members supporting a rotation axis of the driving motor; a condenser provided to condense a refrigerant gas compressed from the turbo compressor; a refrigerant supplying part supplying a part of a refrigerant discharged from an outlet of the condenser to the turbo compressor to cool down the driving motor and the bearing members; and a refrigerant discharging part provided to discharge a cooling refrigerant supplied by the refrigerant supplying part and passing through the turbo compressor. Thus, the refrigerating apparatus cools a driving motor and a bearing member of a turbo compressor without difficulty. Also, the refrigerating apparatus restrains a refrigerant from leaking between an impeller and a diffuser, and increases the efficiency of the turbo compressor.
