More Information
Summary:A refrigeration device (1) includes a blow-out temperature detector (SS) that detects the blow-out temperature of air blown out into the interior of the device, a cargo temperature detector (CS) that detects the temperature of a cargo, an operation controller (51) that performs cooling control of the interior on the basis of the detection temperature from the blow-out temperature detector (SS) and the detection temperature from the cargo temperature detector (CS), a storage unit (52) that stores a first set temperature (A) as a control target value for the blow-out temperature and a cargo target temperature as a target value for the temperature of the cargo, and a time measurement unit (53) that measures a treatment time elapsed for low-temperature treatment of the cargo. The operation controller (51) is configured to control the refrigerant circuit so that the blow-out temperature approaches the first set temperature (A). The time measurement unit (53) is configured to start measuring the treatment time when the temperature of the cargo is lower than the cargo target temperature.
