3C (CAD/CAM/CAE) method is put forward to optimize the structure of TSSC (twin-spirals scroll compressor) from conceptual design to finished products. The mathematical model and virtual model of TSSC are developed. A novel algorithm GA-HPSO combining with the advantages of GA (genetic algorithm), SA (simulated annealing) and PSO (particle swarm optimization) and NN (neural network) is applied to TSSC performance prediction. The swarm intelligence algorithm is used for structure optimization, and the final optimization design variables are gotten. CAE is performed to study the two key components of TSSC-orbiting and fixed scroll, which is useful for improving the quality and reliability of manufacturing and assembly accuracy at the later stages. The prototype of TSSC is manufactured based on 3C. The analysis results show that 3C method can well overcome the blindness and limitation of the traditional design. It offers a new method and idea for wide application of the scroll compressor

“…Mechanical loss not only reduces the overall efficiency of the equipment but can also decrease its operational reliability due to wear and tear caused by the friction between rubbing components. In conventional positive-displacement mechanisms, [1][2][3][4][5] friction issue is always induced by high relative velocities between the sliding components, especially in high-speed applications. These conventional structures make it difficult to improve the relative motion between sliding components, which in turn limits the improvement of mechanical efficiency.…”

This study introduces a new type of end-face structure with polytetrafluoroethylene seals that improves the reliability of the synchronal rotary multiphase pump (SRMP). End-face models, including the relative motion and friction loss between the rotor and cylinder end faces, are established for both the original and the improved end-face structures. The end-face friction losses are analytically investigated based on the theoretical calculations. Due to the low relative velocity between the rotor and cylinder end faces, the end-face friction losses for both of the end-face structures are found to be insignificant compared to the total friction loss in the SRMP. The increased end-face friction loss caused by the polytetrafluoroethylene seals in the improved end-face structure is also negligible. Assessment of the friction losses of two end-face structures in high-speed and high-pressure applications shows that the improved end-face structure exhibits better performance than the original. The parametric analysis suggests that the wider but taller cylinder is helpful in reducing the end-face friction loss of SRMP.

In two companion papers, simulation models for the working processes of liquid-flooded scroll compressors and expanders have been developed and validated against experimental data. In this study, analytic models are presented for the modes of irreversibility generation in the liquid-flooded scroll compressor including built-in volume ratio maladjustment, pressure drop and leakage. A thermodynamic model is used to derive the ideal volume ratio for a liquid-flooded compressor, which is higher than that of dry compression. An optimum set of built-in volume ratio and scroll base circle radius is found which maximizes the overall isentropic efficiency by minimizing the leakage and pressure drop irreversibilities. The irreversibility generation models are used to optimize a scroll compressor for the Liquid-Flooded Ericsson cycle application. The model predicts scroll compressor overall isentropic efficiency of over 80% (based on the shaft power) at an oil mass fraction of 88%.
