The humid regeneration air duct must be insulated to prevent condensation on the inner wall
of the piping when the dew point temperature of the air in the piping is higher than the outdoor
air temperature, which can cause corrosion and water accumulation in the piping.
The dry air outlet of the dehumidifier can be equipped with a control valve that can be used
to control the operation of the dehumidifier. If you want dry air to contain lower humidity,
you must install a control valve at the dry air outlet. If maximum dehumidification capacity
is not required, install a damp air outlet damper.
3.7.1
Connecting the air recirculation ducts
The unit can be installed in a room or a separate room where dehumidification is required.
For best performance, the fan outlet must be equipped with a diffuser
.
3.7.2
Connecting the regeneration air outlet ducts
Moist air must be vented outside. The length of the duct should be as short as possible
to minimize the chance of damp air condensing. The duct must be slightly inclined towards
the outlet to prevent condensate from flowing back into the dryer. If the regeneration duct
is particularly long or must be installed vertically, it must be thermally insulated and a drain
point provided at its lowest position. The air duct outlet must be equipped with a metal grill
or mesh to prevent debris from entering
.
3.7.3
Connecting the regeneration air inlet ducts
It is desirable to minimize the length of the regeneration air inlet duct as much as possible.
To prevent debris from entering the air duct, equip a metal mesh at the inlet. In some conditions,
other ducts may be used for the connection, and an air flow control valve must be installed
on the duct to ensure correct adjustment of the regeneration air flow during the trial run
.
3.7.4
Installing the dehumidifier in the room to be dehumidified
If the unit is installed in a room requiring dehumidification, the process air inlet does not
necessarily require a duct connection. A protective mesh is required at the process air inlet.
The dry air outlet must be ducted and separated from the air inlet of the dehumidifier
so that the dry air can be evenly distributed throughout the room.
Air intake for regeneration should be carried out outside the room to be dried. Otherwise,
due to rarefaction, an uncontrolled suction of moist air from the street or from neighboring
rooms is possible into the room being dried. The regeneration air must be discharged outside.
