Résumé

Efficiency of hermetic reciprocating compressors, which are used in household refrigerators, is subjected to thermodynamic, mechanical and electrical losses. Heat transfer analyses reveal reference points that involve improvement of the compressors. A proper understanding of heat transfer and temperature distribution of various components in the compressor helps in determining the parts geometry and materials selection. However, the temperature of each one of the compressor components is affected by several phenomena that act simultaneously, making the temperature distribution particularly difficult to predict numerically. This paper presents computational thermal analysis of components of a reciprocating compressor and comparison of the results with the measured data. Especially, the influence of component materials of discharge region is investigated. Analyses are carried out by commercially available CFD code with use of temperature, mass flow rate and pressure values obtained from experimental studies as boundary conditions.
