Update time : 2020-02-21 17:48:37

The horizontal concealed fan coil unit is installed above the ceiling that we cannot see, and the air outlet can be seen, and the installation position of the fan coil is not far away. Generally, it is not necessary to send back the air return plenum when installing the fan coil unit. The air above the ceiling directly enters the air inlet of the fan coil, and the installation environment of the air return plenum of the fan coil is determined. For example, the air flow in the place where the horizontal concealed fan coil unit is installed is not smooth, which will affect the air output of the horizontal fan coil. The output air volume required by the corresponding model of fan coil
unit cannot be reached. After installing the air return plenum, the air entering the fan coil unit enters from the air return plenum, which is the function of the air return plenum.

As for the function of horizontal fan coil unit air return plenum, I think everyone should know it. Most installation of fan coil unit does not require air return plenum, and air return plenum is only required under special circumstances.
