3.2.2. Humidity in the installation room
If the unit is installed in a room with high humidity, condensation may occur on the walls of the unit in cold weather con-
ditions. Newly built flats or homes have high probability of condensation, especially in the first year, until the construction or
finishing materials haven’t dried up completely. When installing the unit in the rooms with a high probability of condensa-
tion (For example, in bathrooms), it is necessary to ensure that the condensate does not damage the building structures or
furniture.
To reduce condensation on the outside of the AHU, the following is recommended:
• maintain a lower relative humidity in the room where the AHU is installed;
• install a pre-heater to increase the air temperature of the outdoor air entering the unit.
• if the air is drier outside, you can increase the ventilation intensity and the temperature settings so that the rooms are
dried faster. For this purpose, you can also use the “Humidity control function” (see “Domekt User Guide”).
If the unit is shut down in cold outside temperatures, due to free air circulation, condensate can form inside of the unit,
therefore, it is important to install air closing dampers (motorized are recommended) to close the air intake and exhaust
openings when the unit is OFF. This will prevent cold air from the outside and warm air from the premises to enter the unit.
We recommend that you always keep the unit turned on and use it at minimum of 20% intensity even
if no ventilation is required. This will ensure good indoor climate conditions and reduce condensation
inside the unit, which might damage electronic components.
CF air handling units with a counter-flow heat exchanger are prone to condensation at low outdoor
temperatures. For this reason, these units must be equipped with a proper condensate drainage sys-
tem (see Chapter “Connection of a Condensate Drain”).
