摘要
研究通过Fluent与Actran联合仿真,分析了空调系统风管三通管路在不同入口流速、风管形状、支管流量比及气流进出口形式下的气动噪声特性。结果表明:入口流速4m/s至8m/s时,干管和支管噪声增幅不同;圆形风管降噪效果最好,矩形最差;支管流量比小于50%时,对支管噪声影响较小;分流三通组合1和合流三通组合4在噪声控制上更优。研究为空调系统三通管路的降噪设计提供了理论支持和实践指导,有助于改善建筑声学环境、提升空调性能和降低噪声污染。
This study analyzed the aerodynamic noise characteristics of the three-way pipe in the air conditioning system under different inlet flow velocities,pipe shapes,branch flow ratios,and air inlet and outlet forms through the joint simulation of Fluent and Actran.The results show that when the inlet flow velocity is between 4 m/s and 8 m/s,the noise increase of the main pipe and the branch pipe is different;the circular pipe has the best noise reduction effect,while the rectangular one is the worst;when the branch flow ratio is less than 50%,it has a relatively small impact on the noise of the branch pipe;the combination 1 of the divergent three-way and the combination 4 of the convergent three-way are superior in noise control.This research provides theoretical support and practical guidance for the noise reduction design of the three-way pipe in the air conditioning system,which is helpful to improve the acoustic environment of buildings,enhance the performance of air conditioning,and reduce noise pollution.
