摘要
该文测量了不同运行状态下圆管内流动水发生结冰的时间 ,研究了水的流速不变时圆管内表面温度对结冰发生的影响 ,研究了水的流动状态对结冰发生的影响 ,提出了防止圆管内流动的水发生结冰的条件 。
The freezing duration of the water flowing inside a circular tube under different conditions was measured. The influences of the temperature of inner surface of the tube wall and the water flow conditions on freezing were studied. The principle to prevent freezing of water flowing inside a circular tube was described. The experimental results were theoretically explained. This study is especially useful for the solar hot water system.
