description: ABSTRACT86 pages, 5 pictures, 12 tables, 5 sources.Topic of the final qualification work: âDevelopment of a centrifugal compressor for an industrial plant with a heat output of QH=600kW; lower level temperature 276.5Kâ¦293K; upper level temperature 348K.This work is devoted to the development of a centrifugal compressor for an industrial plant. Calculations and tasks that were carried out during the development of the compressor:1. Construction of the cycle of the refrigeration machine.2. Variant calculations for different refrigerants.3. Gas-dynamic calculation of the main variant.4. Gas-dynamic calculation of an alternative option.5. Calculations of the critical speed, axial force, thrust and thrust bearings for specific pressure and strength calculation.As a result of preliminary variant calculations, R134a freon was chosen as the working substance, since it is, according to its working the preferred refrigerant and is also ozone friendly. As the main option, a compressor was calculated in a two-stage performance because it has less Mach number (at ÐU=18). But since the value of the Mach number is still high, it was decided make both steps axial-radial. In axial-radial steps, the average radius is smaller than in radial ones, which in turn reduces the circumferential speed.
