Summary

Ice storage is a promising technology for energy saving. Ice slurry is favorable material for ice storage. To overcome the shortcomings of the present method of ice slurry production, a new ice storage system is developed to produce ice slurry with low humidity. It drives a liquid desiccant cycle to obtain an environment of low water vapor pressure. Droplets keep on evaporating in such an environment and become super-cooled. Then the super-cooled state will be released with a releaser to get ice slurry in the same way of the conventional super-cooled water method. The system mainly consists of two important processes, liquid dehumidification and evaporative super-cooling. These two processes were investigated by experiments. The results prove the feasibility of the new system and expose some method for future optimization. Meanwhile, Ice slurry was formed in the experiments, which shows a good potential of the system.
