A kimchi refrigerator is a refrigerator designed specifically to meet the storage requirements of kimchi and facilitate different fermentation processes. Kimchi usually becomes too sour when stored in a conventional refrigerator for about a week. In contrast, kimchi can be stored up to 4 months without losing its qualities in a kimchi refrigerator.[1] The kimchi refrigerator aims to be colder, with more consistent temperature, more humidity, and less moving air than a conventional refrigerator, providing the ideal environment for fermentation of kimchi. Some models may include features such as a UV Sterilizer.[2]

In a consumer survey aimed at Korean homemakers conducted by a top-ranking Korean media agency in 2004, the kimchi refrigerator was ranked first for most wanted household appliance.
