Summary

Ice slurry, a suspension of water and fine-grained ice particles, serves as an eco-friendly, pumpable secondary refrigerant with high latent heat capacity, beneficial for cooling systems. Traditional production methods face issues like mechanical wear, need for separate refrigeration, use of disadvantageous refrigerants, inefficiency, and scalability problems. As part of the KETEC project, funded by the German Federal Ministry of Education and Research, an alternative method was developed by dispersing a refrigerant (e.g., CO2) and water at high pressure, then expanding them to form ice particles through different cooling effects. Early experiments validate the theoretical approach, producing fine-grained ice slurry in a simple batch reactor setup. These experiments also provide insights into side effects like foam or gas hydrate formation.
