摘要
分析了液氮储罐预冷时的热力过程，得到了定压下储罐液氮流量和储罐温度、储罐温度与预冷时间的关系，为制定液氮储罐预冷方案提供了理论依据。
This paper presents the analysis of thermodynamic process for the precool of liquid nitrogen storage tank,and some informations such as liquid nitrogen flow rate ,temperature of storage tank as well as the relationship between storage tank temperature and precool time under constant pressure,and provides the theorectical basis for establishing precool scheme of liquid nitrogen tank.
