What are the benefits of installing an electric two-way valve for your customers?

Open-mounted unit:
It is directly placed indoors without decoration, but the unit whose appearance color is in harmony with the room tone should be selected.
Concealed unit:
It should be equipped with air supply and air return ports coordinated with architectural decoration and equipped with air outlet filters at the air return ports.
Horizontal installation unit:
Mostly hidden on the ceiling.



Removable or openable maintenance openings should also be left in the building decoration, so as to facilitate disassembly and overhaul of the fan and motor of the unit and cleaning of the air heat exchanger.


There are two air supply modes for horizontal unit installation: the ceiling of the upper side delivery box supplies air downward.
If the side delivery model is adopted:
the fan coil with low static pressure can be selected, and the outlet of the unit is directly connected to the double-layer louver;
If ceiling downward air supply is adopted:
a high static pressure fan coil should be adopted, and the air supply outlet of the unit can be connected with a section of air duct, which is connected with several diffusers for downward air supply.

There are two ways to return air to horizontal concealed units:
Setting louvers or other forms of air return outlets and air outlet filters on the ceiling, connecting to the air return box of the unit with air pipes, without air pipes.
Indoor air enters the ceiling and is sucked by the units placed on the ceiling.

In addition, attention should be paid to the noise control requirements of the room when selecting fan coil units.
