Test and analysis of fluidized ice machine with dual evaporator

WANG Zepu;WANG Feibo;LI Minxia;MA Yitai;School of Mechanical Engineering, Tianjin University;  
The theoretical cycle of the fluidized ice making machine under the chilling mode and ice making mode was analyzed. It is found that the traditional single evaporator(ice slurry generator) based on the ice making mode couldn't match the performance of the compressor, resulting in lower efficiency of chilling mode, the dual evaporators were proposed to optimize the fluidized ice making machine. The performance of the ice making machine with single and dual evaporators was tested under different ice making solution flow rate. The results showed that the ice cooling rate increased by 34% and 56%, and the coefficient of performance increased by 9% and 54% with dual evaporators under 2000 L·h~(-1) and 2500 L·h~(-1) respectively when compared with the single evaporator fluidized ice making machine. The efficiency of ice making machine was enhanced during the process from a normal temperature to a rated concentration of fluidized ice. The cooling rate and coefficient of performance were improved much more, especially in the case of larger flow rate of the ice making solution. It is proved that the fluidized ice making machine got optimized and the efficiency of ice making process was enhanced with dual evaporators.
