Cold storage is the one of refrigeration equipments.Cold storage means to make a environment different from outdoor temperature and humidity by artificial means. It's also a constant temperature and humidity storage equipment for food, liquid, chemical, medicine, vaccines, scientific experiments and other items.Cold storage is usually located near the port of shipment or the place of origin.Compared with the refrigerator,cold storage is larger. But they have the same refrigeration principle.

Let's see how many kinds of cold storages.

    Small cold storage: Volume is smaller than 500m³.

    Middle cold storage:Volume is between 500~1000m³.

    Large cold storage:Volume is larger than 1000m³.

2. According to temperature:

    High temperature cold storage: -2℃~-8℃ 

    Medium temperature cold storage: -10℃~-23℃

    Low temperature cold storage: -23℃~-30℃
