Inlet diffusers, extract louvers and cooker hood
Supply air diffusers have to be placed in the living area such as bedroom and living room, while the
exhaust air louvers are placed in wet areas (bathrooms, laundry, etc.), toilet and kitchen
Note: Although the cooker hood connected to the unit it also must be mounted separate exhaust
louver in the kitchen
.
The AHU 300 cooker hood outlet is led directly to the exhaust fan without the smell and pollutants
carried through the heat exchanger. In order to achieve heat recovery from ventilation due to exhaust
louver in the kitchen, therefore, this exhaust louver has to be connected together with the exhaust
from the wet cells
Cooker hood must be equipped with dampers which are dense in the closed position
(without opening for the basic ventilation). If there are any «leakage» in the extract pipe
from the cooker hood when the cooker hood isn’t activated then there will be a “Rotor
fault” alarm.
It is very important that there are a signal from cooker hood connected towards the KV plug
outside the unit to avoid this “Rotor fault” alarm.
Exhaust air louvers can be mounted in the ceiling or wall. Supply air diffuser can be mounted in the
ceiling or "low wall". In "low wall" must sectorial aperture positioned so that supply airstream carried
upwards along the sloping ceiling. Supply in the wall at the horizontal ceiling must have “throwing
direction", so that air enters the room along the ceiling. Air supply via the outlet valve allows air jet
throw length, and the exhaust air diffusers can therefore be used as supply air diffuser in the wall
when there is ridge ceiling.
The diffusers should be mounted in frames, so that they can be
easily removed for cleaning.
4 Setting the airflow.
As default setting may supply air diffusers core is opened from 5
to 7 turns from the closed position and locked with a centre nut.
Exhaust louvers core is opened 10 turns from the closed position
and locked with a centre nut. For adjustment of air flow to each
room the settings for the diffusers must be measured. Balancing
scheme (diagram) intended by design, or alternatively by
balancing acc. flow measurements with equipment specifically designed for this.
