【英文篇名】 Characteristics and mechanism of designed supercooled-water ice making system with closed ice maker 【作者中文名】 张君瑛; 章学来; 吴喜平; 何永丰; 郁庆庆; 葛轶群; 【作者英文名】 Zhang Junying; Zhang Xuelai; Wu Xiping; He Yongfeng; Yu Qingqing and Ge YiqunShanghai Maritime University; Shanghai; China; 【作者单位】 上海海事大学; 同济大学; 广州贝龙热力环保有限公司; 上海海事大学 同济大学; 【文献出处】 暖通空调, Heating Ventilating 动态制冰; 蒸发温度; 水流量; 冻结; 【英文关键词】 supercooled water; dynamic ice making; evaporating temperature; water flow rate; freeze; 【摘要】 在自主开发的过冷水制冰试验台上,对不同蒸发温度和水流量下的运行情况进行了分组试验。分析了不同因素对系统稳定运行、过冷水产生和制冰效果的影响,并从机理上分析了试验现象。试验结果表明,自来水较纯水更易发生管内冻结,蒸发温度与流速对管内冻结有较大影响。 【英文摘要】 With a designed supercooled-water ice making system test-bed, carries out grouping experiments for different evaporating temperatures and water flow rates. Analyses the influence factors of the system stable running, supercooled water formation and ice generating effect, and gives explanations on their mechanism. Concludes that tap water is easier to freeze compared with pure water, and evaporating temperature and water flow rate have greater impact on freeze in pipe.
