PROBLEM TO BE SOLVED: To provide a refrigerator for suppressing decay of fish to store.SOLUTION: A refrigerator 100 includes: a storage room 1000 storing fish; an ultraviolet light source 10 outputting light having wavelength of an ultraviolet region; a camera 11 photographing an ultraviolet image including eyes of the fish receiving light from the ultraviolet light source 10; an estimation unit 2 estimating a decay period of the fish on the basis of a luminance value of the eyes of fish in the ultraviolet image including the eyes of the fish; a temperature control unit 3 which acquires information on a storage time and outputs a control signal lowering temperature of the storage room 1000 in the case where a time of day shown by information on the storage time is later than the estimated decay period of the fish; and a cooling unit 1001 lowering the temperature of the storage room 1000 on the basis of the control signal.SELECTED DRAWING: Figure 1 |
