plate 4 has round staggered perforations whose diameter is 3 mm
and pitch 6 mm. The Circular Opticlean is connected to the duct
system via a flexible duct 9 or a connection box 8. It is fixed to the
ceiling tile using fixing clips 2.
Mode of operation
n·


The supply air is discharged very uniformly through the perforated
faceplate and spreads radially in the horizontal plane. As it induces
indoor air, the air flow velocity and the difference in temperature
Connection box
L
between the supply and indoor air decrease rapidly; this results
in low indoor air velocities and uniform indoor air temperatures.
The induced indoor air does not come into contact with the perfor-

ated faceplate because a layer builds up under the air outlet and
acts as an air cushion. This considerably reduces the dirt accu-

The overall height is based on a minimum bending radius of R/D = 0.5.
Smaller radii are possible depending on the type of flexible duct used.

The outlet layout must comply with the maximum allowable indoor air velocities u in the occupied zone in the cooling mode.
The indoor air velocity depends on the cooling load that is to be
removed from the room. The maximum specific cooling capacity
q· depends on the discharge height and the maximum allowable
indoor air velocity u (Graph 1).
Graph 1 enables to determine for the cooling mode the maximum
specific volume flow rate V·
