3 Construction and operation
3.1 Construction
RoofVent
®
units consist of the following components:
■
Roof unit with energy recovery
■
Below-roof unit
The components are bolted together and can be dismantled. The connections of
the coil are located under the extract air grille as standard. The heating/cooling
section can also be mounted on the connection module turned round.
3.2 Air distribution with the Air-Injector
The patented air distributor – called the Air-Injector – is the core element. The air
discharge angle is set by means of the infinitely variable guide vanes. It depends
on the air flow rate, the mounting height and the temperature difference between
the supply air and room air. The air is therefore blown into the room vertically
downward, conically or horizontally. This ensures that:
■
with each RoofVent
®
unit a large area of the hall can be reached,
■
the occupied area is draught-free,
■
the temperature stratification in the room is reduced, thus saving energy.
