| 摘 要： | 在采用液氮制冷的低气压试验箱的设计中,用常规工程设计方法计算的降温过程冷负荷过大,从而导致真空系统设计容量过大。本文采用分布参数模型对试验箱低气压条件下降温过程的冷负荷进行了精确仿真模拟,以此作为真空系统容量设计的基础,减小了设计规模,取得了良好的效果。

| Abstract: | A novel simulation technique has been successfully developed to improve the design of low pressure test chamber cooled by injection and pumping out of liquid nitrogen. Its advantages over the conventional technique include high efficiency and considerable reduction of liquid nitrogen injection. |
