VENTILATION SYSTEM

4

WARNING

If ventilation of the dwelling is closed,
it also prevents new, clean outdoor air
from coming in and dirty air from
going out.

Impurities emanating from human
bodies, structures and the soil, such as
carbon dioxide, humidity, smells,
formaldehyde, dust and radon, quickly
spoil indoor air and cause health
damage.

Too high a humidity may destroy the
building structures and cause mould
and fungus growth. Therefore, the
building regulations require ventilation
to be continually in operation and the
level of ventilation to be adjusted as
needed by the user.

!

As the name says, a dwelling-specific ventilation system (blocks of flats, terraced houses) is
meant for only one dwelling.

The system includes two sides. The extract air side takes dirty and humid air out, while the
supply air side brings a corresponding amount of outdoor air in.

Ventilation in the rooms is continual and can be regulated as needed. Outdoor air is mainly
brought to the bedrooms, sitting room, fireplace room, dining room and sauna. From these
rooms supply air can flow freely, for instance through door vents, to the bathroom, sauna,
toilet, walk-in wardrobe, kitchen and other rooms with air extraction vents. If also cold outside
air comes in to the sauna, only use it when needed as combustion air for a wood heated
sauna oven.

The resident may regulate the power of ventilation (air circulation) as needed.

Filtering

Outdoor air is filtered before taking it in to the dwelling. A coarse filter first removes the
biggest litter particles, thereby preventing the system from getting dirty. After that air passes
through a fine filter, which catches finer dust and even the smallest pollen particles.

Heating of outdoor air

During the heating season, heat included in extract air is used to heat air coming from the
outside. Heat travels in the heat recovery cell through panels, and extract air never mixes
with air coming inside. This may provide all the heating needed. The ventilation units may,
however, be equipped with a post-heating radiator, which can be used to warm air if more
heating is needed.

When temperature in winter falls below –10…–20 

°

C, the intake of outdoor air is restricted

by stopping the supply air fan. This prevents the water that condenses in the unit from extract
air from freezing.

For indoor air to stay healthy and beneficial also for the structures of the dwelling, ventilation
has to be in operation continuously. It is not advisable to stop ventilation even for longer
holidays because it makes indoor air stuffy. Also, during the heating season indoor air
humidity may condense in the ducts and structures and therefore cause humidity damage.
