A refrigeration device has an energy saving operation mode having a first operation that operates a compressor (11) and an in-chamber fan (16) while adjusting the cooling ability of an evaporator (14); a second operation that, when the discharge-side air temperature in a chamber is maintained at a set temperature during the first operation, stops the compressor (11) and the in-chamber fan (16) after increasing the cooling ability of the evaporator (14) to reduce the discharge-side air temperature to a lower limit temperature of a target range including the set temperature; and a third operation for resuming the first operation when the discharge-side air temperature rises after the second operation to an upper limit temperature of the target range. The energy saving mode is adapted to start the in-chamber fan (16) so that, if the suction-side air temperature rises to a limit value after the second operation, the in-chamber fan (16) discharges a less volume of air flow than in the first operation. |
