6 FAQs about [Industrial ice slurry cold energy storage]

What is ice slurry used for?

Ice slurry is widely used in food transport and cold energy supplies. In summary, cold energy storage with ice slurry materials has significant potential in the fields of cold chains and cold energy supplies. The State Council of China recently released an announcement regarding the cold chain development of the “14th Five-Year Plan”.

What is slurry cold storage?

Currently, key research on slurry cold storage mainly focuses on ice slurry and hydrate slurry. Studies indicate that when the IPF is between 20%–25%, the flow resistance of ice slurry is similar to that of frozen water, but the cold storage capacity is several times that of frozen water under the same conditions.

Why is ice slurry used in Mobile Cold energy storage?

Typically, PCMs are utilized in mobile cold energy storage because the latent heat is significantly greater than sensible heat. Ice slurry is an excellent PCM for mobile cold-energy storage as it is inexpensive, convenient, nontoxic, and environmentally friendly. Ice slurry is widely used in food transport and cold energy supplies.

Why does ice slurry have a high energy storage density?

Ice slurry has a high energy storage density because of the latent heat of fusion of its ice crystals. It also has a fast cooling rate due to the large heat transfer surface area created by its numerous particles.

What is the carrier liquid of ice slurry?

The carrier liquid of tap water ice slurry is water, and that of the binary ice slurry is an additive solution. In mobile cold storage, it is necessary to maintain a relatively balanced ice packing factor (IPF) of the ice slurry to prevent it from premature melting, which would lead to a loss of cold energy.

Can ice slurry be used as a cold storage medium?

Ice slurry can also be used as a cold storage medium in various vessels without built-in refrigeration systems such as ice slurry cooled trolleys, trucks or fishing boats.
