  • Numerical performance analysis of the vane-roller integral type swing compressor was conducted. The swing compressor has been investigated for the highly efficient air conditioning system. Performance analysis results of the swing compressor were compared with those of a conventional rotary compressor. Mechanical and gas losses of a swing compressor were larger than those of a rotary compressor. However in case of mass flow rate from the discharge port, the swing compressor was about 6.68% higher than the rotary compressor. Hence the EER, the cooling capacity and the compressor work of the swing compressor were about 3.71%, 6.69% and 2.90% higher than the rotary compressor respectively.

  • An analytical study was carried out to investigate the performance of an oil pumping 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 oil gallery.
