COMMISSIONING
Requirements
Operational requirements for the ventilation unit:
•
Supply and exhaust air temperature below +55°C.
•
Exhaust air temperature at least +10°C
•
Supply air temperature for heat recovery over +5°C
•
Supply air temperature over +10°C
•
All foreign objects have been removed from the
ventilation system
•
Both fans are running
Air flow adjustment
When the unit has been switched on, the air flows must
be adjusted to the designed values.
•
The air flows are adjusted in connection with the
commissioning of the ventilation unit.
•
The adjustment is made separately for both fans in
each operation mode (= at each fan speed).
Check the following during the adjustment:
•
All filters are clean.
•
All supply and extract air vents, the roof inlet, and the
outdoor air grilles are in place.
To achieve optimum adjustment values, the air flows
must be measured at each duct opening. A suitable
measurement device is a thermoanemometer or
a differential pressure gauge. With the aid of the
measurement values, the air flow can be adjusted to
match the design values.
A correctly adjusted ventilation unit is quiet and provides
a good thermal economy. In addition, it also maintains
a slight negative pressure in the house. The negative
pressure prevents humidity from entering the walls and
ceiling.
