Design

The BIA-ID underfloor induction unit provides efficient cooling or heating for applications such as offices. It is specially ideal for rooms with floor-to-ceiling windows that have specific cooling and heating demands. BIA-ID can be installed as single module or in a continuous arrangement.

BIA-ID consists of a plenum box, air distribution plate, casing with feed-through for water connections and electrical cables, adjustable feet, heat exchanger, air deflectors, cover plate and grille.

The heat exchanger is available as 2-wire (change-over operation) or 4-wire.

Functionality

Primary air from the air handling unit provides BIA-ID with supply air via the plenum box. The supply air is forced in at high speed through the air distribution plate, resulting in the surrounding air being drawn in and mixed with the supply air. This generates negative pressure by the heat exchanger.

Room air is continuously drawn from the room through the heat exchanger fins where it is cooled or heated before it mixes with the supply air. The mixed air is then fed through the air deflectors and distributed into the room via the grille.

The proportion of the recirculated room air is much greater than the primary air.
