Ice slurry has been widely used in many fields because of its thermal properties

and ice-making technology has become a focus of study. Dynamic ice-making with supercooled water is one of the most promising method in making ice slurries

but the major defect of this method is that the ice blocking easily take place in the supercooled heat exchanger. Based on the theory of water crystallization and the analysis of the influence factors of ice blocking

a nano-fluorocarbon coating was used to improve the surface conditions of the supercooled heat exchanger and to restrain water from freezing. It is concluded that the nano-fluorocarbon coating will effectively restrain crystallization on the wall and improve the efficiency of the ice-making unit

which results in the decrease of ice blocking and the energy consumption. The investigation will benefit in developing and improving anti-icing techniques.
