description: The theme of the final qualifying work: "Development of a draft design of a centrifugal refrigeration compressor for a ship air conditioning unit with a pressure ratio of 6.07 and a volumetric capacity of 128 m3 / min."This work is devoted to the development of a centrifugal compressor for a ship air conditioning unit. 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, refrigerant R134a was chosen as the working substance, since it is the preferred refrigerant in terms of its operating parameters and is also ozone-friendly. As the main option, a two-stage compressor was calculated, since it has a smaller Mach number (at Ñ±Ð¢ = 0.73 MU= 1). But since the value of the Mach number is still high, it was decided to make both stages axially radial. In axial-radial steps, the average radius is smaller than in radial ones, which in turn reduces the circumferential speed.
