Crystallisation of water in aqueous solutions used as ice slurries.

Author(s) : CHEGNIMONHAN V., BONJOUR J., AYEL V., et al.

Summary

Ice slurries are considered as promising secondary refrigerants in the context of avoiding large size direct-expansion refrigeration systems. They are usually obtained from the partial crystallization of water-antifreeze solutions. This communication addresses the fundamental mechanisms of crystallisation of mono propylene glycol (MPG) or ethanol aqueous solutions at various mass fractions in a rectangular channel cooled on its sides. First, some experimental results of crystallization experiments will be shown, and particularly the characteristics of the temperature jump following the supercooling break-up.
