FEATURES OF CENTRIFUGAL COMPRESSOR CONTROL UNDER STRICLY SPECIFIED CONSUMER PARAMETERS

This paper investigates the impact of seasonal temperature fluctuations on the operation of industrial compressors working under strictly defined pressure and flow rate parameters. Analysis shows that changes in air density significantly affect compressor performance. Modeling of a K-5500-42-1 centrifugal compressor (two versions) using the SimInTech environment allowed for a comparison of two control methods: air discharge (with energy losses) and the connection of an additional compressor. Modeling results indicate the need for control system optimization to improve energy efficiency and ensure stable compressor operation under various climatic conditions, considering the strict pressure and flow rate requirements. The work highlights the importance of considering the thermodynamic properties of air in the design and operation of industrial compressors.
