Rolling piston compressor Dynamic analysis Sensitivity study Energy Efficiency Ratio Optimization |
Résumé : |
In this paper, numerical studies on size parameters has been conducted to improve the performance of a twin-type rolling piston compressor, which has two cylinders called upper and lower cylinders with phase difference of 180°. In order to verify the computational reliability, the simulated results were compared with experimental ones. Sensitivity analysis of each parameter has been undertaken to investigate the influence of the parameters on compressor performance. Especially, size optimization has been studied to find an optimal combination of size parameters based on the sensitivity analysis of each parameter at the given operational condition and working volume. It was demonstrated that the maximum limits on the valve lift (ymax) and the suction port diameter (D_sp) showed the highest sensitivity to the compressor performance and optimum design condition, which corresponded to an Energy Efficiency Ratio (EER) that is 2.6% higher compared to the reference condition. |
