For convenience of description, wind entering from the first wind inlet 12 is defined as first flowing wind, and wind entering from the second wind inlet 14 is defined as second flowing wind. When the first flowing wind flows in the cavity 11, the refrigerator 2 dehumidifies and cools the entering wind. The cooled wind enters the first passage 31. The temperature of the first flowing air after the temperature reduction process is lower than that of the second flowing air, so that in the heat exchanger 3, the heat of the second flowing air in the second channel 32 is transferred to the first flowing air in the first channel 31, and the temperature of the first flowing air is increased.
