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.
