A new system based on rotary dehumidification is proposed using evaporative supercooled water to create ice slurry. Rotary dehumidification is employed to reduce the steam partial pressure

generating supercooled water droplets outside heat transfer tubes. This design circumvents the high energy consumption associated with the traditional vacuum method. Additionally

when compared with the solution dehumidification method

this system is simple and has better dehumidification performance. A high degree of supercooling of the water droplets was realized

and the regeneration load of the desiccant wheel was supplemented by the condensation heat from the refrigeration system. A complete ice-making system was constructed

and component models for the desiccant wheel

carbon dioxide heat pump

and evaporative ice-making process were established. The feasibility and efficiency of the system were preliminarily verified by simulation

and the influence of the main operating parameters on the system performance was studied. Under optimal operating conditions

the coefficient of ice production performance for this new system exceeded that of the traditional supercooling water method by 25.9%

and the ice-making capacity in a single cycle increased by 4.3 times.
