Description

The OptimAir is a two-way induction type active chilled beam,
integrated in false ceilings. OptimAir is primarily designed to
ventilate, cool and/or heat buildings, where a comfortable
climate and individual room control is needed. OptimAir is
now available with two plenum box options for a medium
(M) or a medium-large (ML) airflow. We also offer two heat
exchanger options to best suit the cooling and/or heating
demand of the air-conditioned zone. OptimAir is designed to
fit most types of suspended ceiling frameworks on the market
with a standard width of 600 mm.
Air duct connection: OptimAir M and ML are available with
with either one or two air duct connections on the side of the
chilled beam. The suggested air duct quantity and dimension
depends on the length, primary airflow and pressure of the
selected chilled beam.

Function

The primary air from the supply air system is connected to
the plenum box and distributed through specially shaped
nozzles. As the air is discharged through the nozzles, the high
velocity air jets above the coil create a low-pressure zone. This
low-pressure zone draws ambient room air through the coil,
and as it passes the coil fins it is conditioned (cooling - heat-
ing), according to the water temperature flowing through the
coil. The conditioned air then mixes with the air jets (venti-
lation air, humidity control) before it is discharged back into
the occupied space. The conditioned/mixed air discharged
along the ceiling provides an optimal Coanda effect which is
always the objective when the occupied zone requires low air
velocities.

Variable nozzles

As standard, OptimAir is supplied with variable nozzles. This
is a unique, elegant and flexible feature, which simplifies
the adjustment of the nozzle positions on either side of the
plenum box to set the required airflow without modifying
the primary air pressure. With the use of an Allen wrench the
airflow can be adjusted in five steps on each side of the chilled
beam, by covering and uncovering the nozzles. This mechan-
ical solution features some very clever engineering, and was
designed to stand the test of time. The requested airflow can
be selected in our selection software, and is factory pre-set
and can also easily be changed on-site.
