Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering, 2023 The most popular approach to determine compressor losses is to generate compressor pressure-volume indication diagrams. The pressure-volume indication diagram of a novel hermetic reciprocating compressor for household refrigerators operating with R600a ...

Waves in Reciprocating Compressors [PDF]
PAMM, 2004 AbstractIn case of fast running reciprocating compressors an oscillating momentum on the piston has been observed. This oscillation has been attributed to internal waves. The aim of this paper is to present a simple model to show how such waves are initiated. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
