When dry ice dissolves, it does not convert from solid to liquid, but directly sublimates from solid to gas. Therefore, its melting does not produce any water or liquid, which is why we call it "dry ice".

Because if dry ice is placed directly in a refrigerator or cold storage without packaging, the temperature regulator of the refrigerator or cold storage will mistakenly think that the temperature is too low and will be turned off, which will shorten the life of the refrigerator. Of course, if there is a power outage, dry ice will definitely keep the refrigerator or cold storage at a good low temperature.

Dry ice and water ice can also be mixed to reduce the weight of all water ice, and dry ice can be used to maintain the cooling durability of water ice.
