8.0.0 Principle of operation
8.1.0 Description
The unit contains a counterflow heat exchanger and two fans, which enable the extraction
of warm air from a room and concurrent supply of cold fresh air from outdoors. Heat
exchange occurs by using the warmth from the extracted air to heat the cold fresh air.
Airflow:
Supply air fan (1) draws in fresh air, passes it
through the filter (3), the heat exchanger (2), up
through the fan blade, out through the louvres
in the top and in to the room.
The extract air fan (4) draws air from the room
through the louvres in the bottom and sides, up
through the filter (5), through the heat
exchanger (2), down through the fan blades,
which blows it out at the bottom of the back.
Bypass:
When the bypass damper (6) opens, the air is
drawn through the unit, bypassing the heat
exchanger and direct into the room.
Regulation:
The temperature desired is set on the control
panel for the supply air.
A sensor registers the actual temperature of the
supply air, and if it is lower than the set value,
the control system will turn down the supply air
volume.
The air will thus be warmer as it passes through
the heat exchanger.
