AI Technical Summary
In existing dynamic ice storage refrigeration devices, ice crystals form and adhere to the outer wall of the inner cylinder, affecting the subsequent refrigeration efficiency.
An evaporation zone is set between the evaporator's insulation shell and the stainless steel inner cylinder. A low-temperature air film is formed by using an inclined jet nozzle. Combined with a rotating water distribution and wall scraping ring mechanism, ice crystals are generated and removed evenly.
This ensures uniform ice crystal formation, prevents adhesion, improves refrigeration efficiency, reduces maintenance costs, and enhances system energy efficiency and reliability.
