Abstract—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 compressor helps in determining the parts geometry and materials selection. However, the temperature of each compressor component is affected by several phenomena that act simultaneously, making the temperature distribution harder to predict.
This paper presents computational thermal analysis of components of a reciprocating compressor and comparison of the results with the measured data. Especially influence of component materials of exhaust region is investigated. Analyses are carried out by commercially available CFD code with use of temperature, mass flow rate and pressure values as boundary conditions which were obtained experimentally.
Index Terms—Compressor, CFD, heat transfer, insulation.
