Title:
SOUND ATTENUATION ASSEMBLY AND AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/089264
Kind Code:
A1
Abstract:
A sound attenuation assembly and an air conditioning system. The sound attenuation assembly comprises a housing (1) and multiple sound attenuation blocks (2). The multiple sound attenuation blocks (2) are spaced apart from each other, and outer edges of the sound attenuation blocks (2) are fixedly connected to an inner side surface of the housing (1). Each sound attenuation block (2) is provided with an air circulation hole (21). The air circulation holes (21) of the multiple sound attenuation blocks (2) communicate with each other, and form a sound attenuation air duct together with the housing (1). The above configuration effectively attenuates sound when an airflow passes through a sound attenuation passage. The sound attenuation assembly can serve as a component to be connected to an air conditioner air duct, such that an airflow in the air duct can undergo sound attenuation by means of the sound attenuation assembly. The invention has a simple structure and is easy to manufacture, thereby simplifying the structure of air conditioner air ducts.
