Résumé

Lubricant oil is needed in air-conditioning and refrigeration systems because the compressor requires oil to prevent surface to surface contact between its moving parts, to remove heat, to provide sealing, to keep out contaminants, to prevent corrosion, and to dispose of debris created by wear. Thus the oil separation in an oil separator is one of the most important characteristics for proper compressor operation. In this study, a gravity type of oil separator is used. Oil separation characteristics have been investigated for CO2/PAG mixture in the range of oil concentration 0 to 5 weight-percent and the mixture temperature range of 0 to 15°C at 50 bar and 70 to 90°C at 80 bar. The results obtained indicate that the oil separation is increased with an increase in the oil concentration. It is also found that the oil separation in liquid state is increased with an increase in the mixture temperature while the oil separation in gas state is decreased.
