Abstract

See full text

In a turbo refrigerator in which: a gas-phase refrigerant from an evaporator is compressed by a turbo compressor and then condensed by a condenser; the obtained liquid-phase refrigerant is evaporated by the evaporator; and a cooling target is cooled down by evaporation heat of the liquid-phase refrigerant, the compressor is a back-to-back two-stage centrifugal type, and the condenser is provided at a position outside a compressor rear stage so as to overlap the compressor rear stage when viewed from each of an axial direction and a radial direction. With this, the pressure loss of a vapor refrigerant is eliminated, and the deterioration in efficiency can be suppressed. In addition, size reduction can be realized by space saving. Further, an evaporated refrigerant can be smoothly introduced to the condenser with a simple configuration.
