Summary

Inorganic salt solutions used for ice slurry generally exhibit severe supercooling and lead to high energy consumption. This study investigates the supercooling characteristics of three chloride salts (MgCl₂, CaCl₂, SrCl₂) and their composite solutions, and conducts tests on vacuum flash ice-making performance. The results show that MgCl₂ solution presents the weakest supercooling effect. Cooling temperature and container material are the dominant influencing factors, while the concentration (1–4 wt%) has negligible impact. The optimal composite solution (0.7 wt% MgCl₂ + 0.3 wt% SrCl₂) suppresses supercooling more effectively than single salts and nanofluids. It achieves the same ice packing factor (IPF) at a lower flash rate, with a latent heat of 268 J·g⁻¹. This work provides technical references for the engineering application of inorganic salt ice slurry.
