The present invention relates to a sterilization device for a low temperature storage house. More specifically, provided is a sterilization device for a low temperature storage house. A sterilization means performs dilution by continuously feeding sterilized air little by little into circulated air while avoiding a direct contact with a stored material, so energy usage is minimized and a sterilizing effect is improved. To this end, a separate sterilization pipe path (duct) (51) is prepared in one side of a transferring pipe (20) while air is circulated in a low temperature storage house (10), and a part of circulated air passing through the transferring pipe (20) is stationed to have a slow flow speed in the sterilization pipe path (51) and is sterilized through a sterilization means (54) such as ultraviolet rays or plasmas. A procedure in which the sterilized air is re-added in the circulated air of the transferring pipe (20) to be diluted is continuously repeated. |
