To provide a refrigerating device capable of improving efficiency in full load, and also keeping high efficiency in partial load, with respect to a refrigerating device using a plurality of refrigerating machines.
This refrigerating device comprises the plurality of refrigerating machines 20-1, 20-2 having evaporators 21-1, 21-2 exerting refrigerating effect by retrieving heat from cold water and evaporating a refrigerant, compressors 23-1, 23-2 compressing refrigerant vapor to achieve high-pressure vapor, and condensers 25-1, 25-2 cooling the high-pressure steam by cooling water and condensing it. The cold water is connected with the evaporators 21-1, 21-2 of the plurality of refrigerating machines 20-1, 20-2 in series, and successively cooled by evaporation heat of the refrigerant of the plurality of evaporators 21-1, 21-2. The cooling water is connected with the condensers 25-1, 25-2 of the plurality of refrigerating machines 20-1, 20-2 in series, and successively cool the refrigerant of the plurality of condensers 25-1, 25-2.
