CFD Simulation On The Oil Pumping System Of A Variable Speed Scroll Compressor
نویسندگان
چکیده
An analytical study was carried out to investigate the performance of an oil supplying system of a variable speed compressor using a commercial CFD program. The simulations for the oil supplying system with the oil and air mixture were performed by varying compressor speed from 40 Hz to 90 Hz. Comparing the predicted with the measured data on the modified scroll compressor validated the simulation model. The predicted results were consistent with the test data with a maximum deviation of 12.8%. The oil flow rate significantly increased with a rise of compressor speed due to a higher oil flow rate from the swing pump and a greater centrifugal force on the oil gallery. This analytical method was proved to be very useful to determine the oil flow rate through the oil gallery and to design an optimized oil gallery for a variable speed scroll compressor.

For a hermetic reciprocating compressor of the household refrigerator, it is not economic to set a separate oil pump, because of cost and space demands. Its oil supply system is mainly promoted by a reed pump and the spiral groove on the shaft. When the compressor is operating, the oil climbs up the inner wall of the reed pump because of the centrifugal force. The height to which the oil could ...
