Abstract: PROBLEM TO BE SOLVED: To provide a storage to preserve freshness to keep vegetables and fruits fresh. SOLUTION: A storage to preserve freshness is equipped with a photocatalytic sterilization and humidification unit 20 which filters air humidified by water in a water tank 22 and an atomizing device 21 by means of an atomizing device 21 atomizing liquid into the air, a device 26 for sending ultraviolet light, and a photocatalytic layer 27 placed on a surface exposed to ultraviolet light. The photocatalytic sterilization and humidification unit 20 is placed in a passage for cold air. Refrigerated articles A inside a storage 19 are kept fresh as the photocatalytic sterilization and humidification unit 20 not only humidifies and gets rid of dust by atomizing liquid into the air but also eliminates and dissolves bacterium and ethylene gas contained in the air by using the device 26 for sending ultraviolet light and the photocatalytic layer 27.
