摘　　要：对刮片式冰浆生成器进行试验研究，探讨不同浓度下的氯化钠溶液结晶的试验过程与现象。试验结果表明：对浓度为3％-5％的氯化钠溶液制取冰浆，能效系数最高达到1．9。纯净水和氯化钠溶液在试验过程中，存在一定的过冷度下才开始结晶，并且随着浓度的增加冰点温度呈线性减小，与理论相比，由于氯化钠溶液在低温下容易发生析晶，试验得到的溶液结晶点温度比理论的温度要高一些。The scraped surface ice generator experimental studied,The different concentrations of sodium chloride solution crys- tallization experiments processes and phenomena was discussed. The experimental results show that：For a concentration of 3% to 5% sodium chloride solution was prepared to take the ice slurry, the highest energy efficiency coefficient can reached to 1.9. Pu- rified water and sodium chloride solution during the experiment,there is a certain degree of sub cooling before crystallization be- gan, and with increasing concentrations of the freezing temperature linearly decrease, compared with the theoretical, since the salt solution of sodium chloride at a low temperature prone to crystallization, under the experimental solution crystallization point tem- perature is higher than the theoretical temperature
