小型窗机滚动转子压缩机气液分离器的结构优化

摘要

To improve the rotary compressor efficiency, the liquid-gas separator's structure was optimized, which was based on a per-existing product. Inner fluid field and pressure field of original liquid-gas separator was investigated through numerical simulation, and then the primary structure leading to pressure drop was analyzed. Furthermore, the improved proposed was proposed. The results show that the primary structure leading to pressure drop were bracket and inner tube, which accounts for 41.58% and 29.52% of to-tal pressure drop. Moreover, the pressure drop of improved liquid-gas separator decreased by 31.35%, and the rotary compressor COP increased by 0.656%.%为了提高滚动转子压缩机的效率，对已有型号的产品气液分离器进行结构优化。用数值模拟的方法研究了原始气液分离器的内部流场和压力场，并分析了造成压力损失的主要结构，提出了改进方案。结果表明：气液分离器中造成压力损失的主要原因是挡板和吸气管口，分别占总压力损失的41.58%和29.52%，改进后最优方案可以有效降低了压力损失31.35%，提高压缩机的COP 0.656%。
