Binary ice: generation and applications of pumpable ice slurries for indirect cooling.

Author(s) : MALTER L.

Summary

Binary ice is a completely safe and very efficient fluid which shows heat transfer coefficients in the same order of magnitude as boiling refrigerant. In sub-zero applications the energy efficiency is at least as good as for direct cooling systems. Binary ice can be generated in different ways. For small and medium capacities, the ice is generated on refrigerant-cooled surfaces (3-500 kilowatts refrigerating capacity) with temperatures between approximately -4 and -40 deg C (Flo-Ice process). This makes binary ice an ideal fluid for e.g. supermarket refrigeration, cold stores, ice banks and a retrofit for underperforming air-conditioning plants. Large capacities, however limited to temperatures at approximately 0 deg C, can be obtained when using the Vacuum-Ice process, where water is used as refrigerant. The ice is generated in a direct contact process without heat transfer surfaces.
