Operating process of a refrigeration low-speed compressor with intensive cooling

Year: 2025

Type: article

Abstract: In the presented work the peculiarities of change of instantaneous parameters of the compressible refrigerant (R134a) during the cycle time, caused by design and mode parameters of the low-speed compressor, are considered. The authors carried out a numerical calculation of the operation parameters of a low-speed refrigeration compressor in the specified ranges of operating parameters and in comparison with a high-speed machine operating on R134a freon. The numerical calculations for the refrigerating low-speed stage on R134a refrigerant allowed to analyse the operating process and to obtain integral characteristics: volumetric effciency, indicative isothermal efficiency, refrigerating coefficient. The prospects of application of low-speed machines as an alternative to single and multi-stage high-speed refrigeration compressors is shown.
