What is the new air outlet?

The new air outlet is a return air outlet.

Because the air conditioning unit is sent indoors through indoor return air, cooled by the coil in the unit, there will be one air outlet and one return air outlet. From the perspective of the unit itself, the air outlet is generally horizontal on the side, with visible fins. The return air outlet is generally at the bottom, with visible fans and filter screens. From the installation and decoration of the air outlet, it can be seen that most of the air outlets use square or circular diffusers, as well as horizontal and vertical fence diffusers. The return air outlet is usually a single layer of fence louvers. There can be one or multiple air outlets, while there is only one return air outlet.
