摘　　要：在岭澳核电站的调试中,发现核辅助厂房通风空调系统(DVN)运行不稳定。不稳定主要是由DVN系统的负压控制部分造成的。本文分析了DVN系统负压控制设计中存在的问题,介绍了在调试过程中采取的改进措施及改进方案。During the commissioning of Ling'ao nuclear power station, it was found that abnormal op-eration in DVN was caused by the unreasonable design in negative pressure monitoring system. This paper emphasizes on the analyzing of how the negative pressure monitoring system works and what is the problem unsolved,and finally introduces the measures and solutions adopted to improve this system.
