Analysis of Discharged Oil Using Visualization Technique for Upper Part and Discharging Pipe of Rotary Compressor
- 발행 : 2005.11.25
초록
An efficiency of a refrigeration cycle and a reliability of a compressor can be reduced if a refrigerant including excessive lubricating oil is exhausted from a rotary compressor. Thus, the oil behavior inside the compressor should be analyzed to improve the efficiency. A tested rotary compressor has been manufactured with visualization windows at upper parts in this study to investigate the oil behavior using developed visualization techniques. Discharge pipe with level gage has been visualized to investigate discharged oil amount. The oil behaviors inside the compressor and discharging pipe at various operating conditions have been analyzed. The results of the visualization for the discharging pipe have been compared with those of the upper part to confirm the accuracy.
