On: Kimchi refrigerator

[limitedfrom]

Not really, the advertised temperatures of most brands' kimchi fridges[1] are -1°C (with lower -0.5°C band of stability as well), which is supposed to be mimicking "buried outside in Korean winters" condition.

[1] Example here https://www.lge.co.kr/support/product-manuals?title=manual&m..., see table on page 10, it's between -0.7°C and -1.7°C for kimchi.
