Comparing properties of aqueous solutions for liquid only and ice slurry applications of indirect systems.

Author(s) : MELINDER Å.

Summary

Indirect systems are increasingly used for cooling cabinets, cold storage and freezers in supermarkets as the primary refrigeration unit then can be designed in a compact way and with an extremely small refrigerant charge. Much research has been carried out with ice slurries. The aqueous solution chosen should have suitable concentration and freezing point, good transport and heat transfer abilities as well as low pressure drop giving small pumping power. The paper includes a comparison of the properties of some aqueous solutions with concentrations typically used for liquid only and for ice slurry in cooling cabinet and freezer applications in a supermarket. This comparison of basic properties shows some advantages with ice slurries.
