Kimchi is a traditional Korean dish consisting of pickled vegetables, which is mainly served as a side dish with every meal, but also can be served as a main dish .In the past, people used to dig a hole in the ground to bury the crock to preserve the kimchi. Though there was no refrigerator, it remained tasty for the next year. Kimchi refrigerators, which are manufactured only in Korea, aim at mimicking the conditions of a clay container buried in the ground. The core difference between a kimchi refrigerator and other refrigerators is that the former directly cools the storage room. Kimchi refrigerators' adoption of direct cooling mimics the cold earth around the pottery that also cools it directly. It maintains a constant temperature and humidity.
