The air conditioner air inlet silencing structure comprises an air conditioner box shell assembly, an air inlet is formed in the side portion of the air conditioner box shell assembly, a sound insulation cover is installed at the position, corresponding to the air inlet, of the air conditioner box shell assembly, the upper side of the sound insulation cover is open, and the lower side of the sound insulation cover is open. Therefore, airflow can be introduced into the air inlet from top to bottom. The air conditioner box has the beneficial effects that after the air conditioner box is installed inside an automobile instrument desk, the sound insulation cover can change the air inlet direction of airflow, the airflow is led into the air inlet from top to bottom, it is guaranteed that a wind noise field generated when the airflow enters the air inlet does not face the direction of a main driver and a co-driver, the purpose of active noise reduction is achieved, and therefore the NVH performance of an air conditioner is improved.
本发明公开了一种空调进风口消音结构及带该消音结构的中置式双层流空调,包括空调箱壳体总成,所述空调箱壳体总成侧部具有进风口,所述空调箱壳体总成在对应进风口的位置安装有隔音罩,所述隔音罩的上侧敞口,以使气流能够自上而下地引入所述进风口。本发明的有益效果是:空调箱安装于汽车仪表台内部后,隔音罩能够改变气流的进风方向,使气流由上至下地引入进风口,保证气流进入进风口发出的风噪声场不朝向主副驾驶的方向,达到主动降噪的目的,从而提升空调NVH性能。
