摘要

针对新能源车用涡旋压缩机在过压缩工况下功耗增加、效率降低问题，提出一种新型副排气孔设计。建立了涡旋和副排气孔几何模型，利用动网格方法，在多种工况下针对不同类型副排气孔进行泵阀联合仿真，研究了副排气孔对压缩机性能的影响机制，并验证了新型副排气孔对压缩机的效率提升效果。仿真结果表明：常规孔型副排气孔受尺寸限制，对压缩机效率的提升较小，而新型渐开线副排气孔具有更强排气能力。渐开线副排气孔设计方法突破了常规孔型副排气孔的尺寸限制，提高了副排气孔排气能力，在2种过压缩工况下，相比采用常规副排气孔的涡旋压缩机，开设新型副排气孔后，压缩机等熵效率分别提升7.9%和3.0%，新型副排气孔降低了压缩机功耗，提高了压缩机效率。

Abstract

A novel design for intermediate discharge ports (IDPs) is proposed in response to the issues of increased power consumption and reduced efficiency. This approach involved establishing a geometric model of the scroll and IDPs

focusing particularly on the involute curve and employing dynamic mesh techniques for pump-valve joint simulations across various operational scenarios to examine the different types of IDPs. This study explored the influence mechanisms of IDPs on compressor performance

demonstrated the limitations of conventional port-type IDPs in terms of size and efficiency enhancement

and validated the superior exhaust capabilities and efficiency benefits of involute-shaped IDPs. The simulation results confirmed that conventional IDPs were restricted by size limitations and offered only marginal improvements in compressor efficiency. In contrast

the involute-shaped IDP provided enhanced exhaust capabilities

significantly increasing the exhaust flow rate

thus reducing the power consumption and boosting the overall efficiency of the compressor.
