Fruit preservation cold storage temperature, high temperature storage: the temperature is generally 0℃~10℃. Low temperature warehouse: the temperature is generally -18~-25℃. Ultra-low temperature cold storage: 0℃~-80℃.

As the name suggests, it can be seen that the air conditioning warehouse is also a kind of fresh-keeping cold storage, but the air conditioning warehouse is more advanced in technology than the ordinary fresh storage.
