Two novel ice-making systems with evaporative supercooled water are introduced with different dehumidification methods.One is the improved ice-making system with liquid desiccant

in which a subsystem of evaporative precooling water is added and the dehumidified air is cooled by cooling water of system itself.The improved system can not only avoid the blocking problem in the traditional supercooled water method

but also can utilize the low humidity ratio air.The other is an ice-making system with condensation dehumidification

which includes two ice-making subsystems

with evaporative supercooled water and supercooled condensed water of moist air separately

and also solves the blocking problem with the traditional supercooled water method.The system is relatively simple in comparison with the improved ice-making system with liquid desiccant.The analysis on thermodynamic properties shows that in comparison with the traditional supercooled water system

the coefficient of performance of the improved ice-making system of evaporative supercooled water with liquid desiccant can be increased by more than 33.8%

while that with condensation dehumidification is basically the same under a certain working condition.
