摘要: 为了确切了解外部参数对冰浆含冰率及冰浆制冷能力的影响，采用了不同加热量和不同流速下的冰浆的融化过程对比分析的试验方法，对不同时间、不同加热量、不同流速下的换热器进出口的冰浆的进出口温度、含冰率进行了测试。结果表明，在各种实验状态下，出口温度达到-3.95 ℃以后，进出口温度都急剧升温阶段；基于不同的质量流速和加热功率，水平管路内部冰浆的持续时间与质量流速、加热功率呈反比，在一定基础上为冰浆空气冷却器设计参数的确定提供技术支撑。Abstract: In order to understand the influence of the external parameters on the ice slurry and the refrigerating capacity of the ice slurry, this paper adopts the experimental method of the comparison and analysis of the melting process of the ice slurry under different heat addition and different flow velocities, and the inlet and outlet temperature and the ice content of the ice slurry in the inlet and outlet of the heat exchanger at different time, heat addition and different velocities are tested. The test results show that both the inlet and the outlet temperatures rise sharply after the exit temperature reaches to -3.95 ℃, and the duration of the internal ice slurry in the horizontal pipeline is inversely proportional to the mass velocity and the heating power based on the different mass flow velocities and heating power. It provides technical support for determining the design parameters of gas cooler.
