Research on key technologies for refined design and operation regulation of ammonia refrigeration system in National Sliding Center

The National Sliding Center for the Beijing 2022 Winter Olympics uses an ammonia refrigeration system to maintain the demand for ice production on the track. How to realize the safe, stable, energy-saving and efficient operation of an ammonia refrigeration system has become the key difficulty and technical core of the project. Therefore, this paper begins with key aspects such as the optimization design of ammonia refrigeration system configurations, comprehensive application of integrated critical equipment, research on automated and intelligent operation control strategies, and the establishment of safety maintenance mechanisms for ammonia refrigeration systems, and conducts research and engineering application of refined design and operation regulation technologies for the ammonia refrigeration system in order to provide technical support for the application of ammonia refrigeration systems in complex engineering projects.
