Résumé

In this study, Heat transfer and temperature distribution in a linear compressor was analyzed by lumped parameter model. The linear compressor has a more complicated suction structure than the conventional compressor because the piston acts as a suction muffler. For this reason, Gas superheating in suction refrigerant is a very important factor in linear compressor design. The control volume consists of the solid element and the fluid elements divided into simplified elements assumed to have uniform thermodynamic properties. To verify the numerical analysis, an experiment was conducted by using calorimeter at steady state. The results of the numerical analysis show good agreement with the experimental data. Suction refrigerant temperature is influenced by mixing ratio at inlet of a muffler. As the mixing ratio approaches to 1, the suction refrigerant flows indirectly. In case of the mixing ratio is 0, the suction refrigerant temperature is 3.45% higher than the mixing ratio is 1. In addition, insulating gasket which prevent heat transfer from discharge part decrease temperature of suction refrigerant.
