过冷法制备冰浆中控制参数对制冰的影响

Effect of Control Parameters to Ice-making of Dynamic Ice Slurry Generation Based on Supercooled Method

过冷法制备冰浆是近二十多年来发展起来的一种新的动态制冰技术,与传统的静态制冰技术相比,有较高的制冰率和能量效率,并提供了含二次冷媒循环的过冷水动态制备冰浆的实验装置。实验采用自来水作为试样,在不同的水流速、二次冷媒温度以及过冷度下进行了对比实验,得出了不同控制参数对制冰的影响。实验数据表明,随着水流速与过冷度的增加,制冰率增大。

Dynamic ice slurry generation based on supercooled method is a new dynamic ice thermal storage technology.Compared with traditional ice-making technology,it has high ice-making rate and energy efficiency.An ice slurry generation based on supercooled method is expounded,using tap water as sample with some comparative experiments under different water flow rates,ethylene alcohol temperatures and supercooled degrees.The effect of different control parameters to ice-making is analyzed.The experimental results show that the ice-making rate is larger with the growth of water flow rate and supercooled degree.
