<p>The prefabricated component is used for ventilation systems which supply hot or cold air from the floor into a room. Alternatively ventilating air can be supplied. The component incorporates all channels and forms part of the floor, with no special regulating slider needed. A waste air channel (9) is open at the top. This projects along the whole building component. An internal, enclosed feed air channel (8) is provided parallel with the waste air channel. an airflow slot is provided for connecting both channels. At a given pressure in the air inlet channel (8) a flow velocity above 10m/s is obtained in the slot.</p> |
