A calculational model for predicting the surge line of a turbocompressor system has been established which is composed of a centrifugal compressor, duct, coolers and condensers (gas-liquid separator). The influences of various parts of the system on the surge point have been studied in detail, and some discussion has been focused on the coolers and condensers. The influences of cooler, condenser and thermodynamic parameters of working medium on stability of the system is calculated and explained. This analysis is useful for predicting system character during the of design compressors and systems, as well as safety for operation of practical industry process.
