| 中文摘要: |
| 空调系统噪声在新车质量研究TOP10问题排名中一直居高不下，但由于其没有直接影响到驾驶安全性而常常被忽略。如今随着消费者以及整车娱乐系统对整车NVH要求的不断提高，降低空调系统噪声被提高到一个新的高度，因此从整车角度列举了产生空调系统噪声的因素，并结合案例，借助CFD分析的方法，对风道内空气流场进行模拟分析，优化结构及布置安装方式，以减小空调系统噪声，希望能为后期空调系统降噪设计提供借鉴与参考。 |
| 英文摘要: |
| Air conditioning system noise has been highly ranked in the new quality study of TOP10 problem, but it＇ s often ignored because of it have not direct effect to driving safety. Now, with consumers and the vehicle entertainment system requirements increasing to vehicle NVH, reduce air conditioning system noise has been raised to a new level, this article list which generate noise factors from the vehicle view, combine with the cases, aid of the CFD simulation analysis method, analysed the air duct flow field, perfect the parts structure and install way, reducing the system noise, hope providing reference for the late reducing air conditioning system noise design. |
