PROBLEM TO BE SOLVED: To provide a turbo refrigerator including a centrifugal compressor suppressing deterioration of efficiency by eliminating pressure loss of a vapor refrigerant, reducing size by space saving, and smoothly guiding an evaporated refrigerant to a condenser by a simple configuration. SOLUTION: In the turbo refrigerator, a refrigerant (R1) of a gaseous phase from an evaporator (1) is compressed by a turbo compressor (2), it is condensed by the condenser (4), an obtained refrigerant (R3) of a liquid phase is evaporated by the evaporator (1), and by this, a cooling object (W1) is cooled by heat of vaporization. The compressor (2) is an addorsed two-stage centrifugal type, and the condenser (4) is disposed in a position overlapping a compressor subsequent stage (2R) as seen from the axial direction (S) and the radial direction (R) in an outer side of the compressor subsequent stage (2R).
