Summary

This article predicts that, thanks to its numerous positive features, the use of ice slurry is likely to develop. Freezing by immersion in a biphasic fluid at a low temperature (-30 or -35 deg C) can certainly be envisaged. Immersion (in a sodium-chloride liquid solution) of shrimps, sardines or even cherries to be candied is at present being used. Ice slurry could also activate freezing and has a large thermal capacity thanks to its solid phase. In indirect refrigeration applications, the benefits are obvious: reduced networks, pumps and accessories; storage; improved plant COP. What hinders development at the moment is the lack of competitive generators, above all in the case of plant with a capacity of 100 to 1000 kilowatts. The wide range of ice slurry generation methods suggests that this problem will be solved soon.
