Air conditioning industry technicians are also hard

The mute thing alone, it seems simple

In fact, it has been a "stubborn disease" plaguing the industry.

Dunan environmental research and development personnel know user pain points

Developed one specifically for this purpose

Don't underestimate this seemingly ordinary accessory

She's a research and development worker in the lab on countless explorations

The optimal scheme is selected from more than 100 noise reduction structures

Successfully achieve significant noise reduction effect

A small technological breakthrough

In fact, it has taken a big step forward in the technological progress of the industry

For the majority of consumers to bring a more comfortable environment experience
