国家雪车雪橇中心氨制冷系统工艺过程控制探讨

Discussion on Process Control of Ammonia Refrigeration System in Yanqing National Sliding Center

本文介绍了应用于2022北京冬奥会国家雪车雪橇中心项目氨制冷系统中高压式液位控制、压缩机组集群控制、氨泵变转速供液控制、油分离器过热度判断控制四种控制方法,并与传统氨制冷工艺过程控制进行了对比分析。

In this paper, four control methods applied in ammonia refrigeration system of Yanqing National Sliding Centre in 2022 Beijing Winter Olympics: High-pressure level control, cluster control of compressor group, variable ammonia pump speed liquid supply control and control of oil separator based on superheat, are introduced and compared with the traditional ammonia refrigeration process control.
