摘要
To prevent other cooled objects from damaging quality, safety, and the like due to odor, admixture and etc. of the cooled object taken into the air which becomes the refrigerant of the air refrigerant refrigerator.SOLUTION: A cooling air generating device of one embodiment comprises: an air refrigerant refrigerator having a compressor that adiabatically compresses ambient air as air refrigerant, a cooler for cooling the air refrigerant discharged from the compressor, and an expander that adiabatically compresses the air refrigerant cooled by the cooler so as to further cool it; a freezer having a cooling space for cooling a cooled object; a feed passage for supplying the air refrigerant cooled by the expander to the cooling space; and a discharge part for discharging the air refrigerant in the freezer to the ambient air, in which the freezer is configured so that the air refrigerant received from the feed passage is used for cooling the cooled object as it is.SELECTED DRAWING: Figure 1
