The WAAB-600 chilled beam is an air/water induction terminal unit that simultaneously provides the
supply, thermal treatment and diffusion of supply air, to set internal conditions at the desired comfort
levels. Chilled beams take advantage of the excellent thermal properties of water to guarantee optimal
comfort levels, with minimal power consumption.
The main heat-transferring component in the WAAB-600 chilled beam is a battery formed by copperThe main heat-transferring component in the WAAB-600 chilled beam is a battery, formed by copper
tubing and aluminium blades. It also incorporates air ducts and a plenum for supplying the ventilation
air, which has been pre-treated in a central air conditioning unit. The WAAB-600 chilled beam can be
supplied with connections on the side or on the top, for both supply air and return air.
The unit can be adapted to modular ceilings measuring 600x600, 625x625 and 675x675 for T24 and
T15 profiles. Thanks to its reduced size, it can also be installed in low-hanging false ceilings.

CONSTRUCTION AND WORKING SYSTEM WAAB 600
The ventilation air is injected through nozzles that cause the air to accelerate and force air induction in
the room, through the battery. Subsequently, the two masses of air (the induced air and ventilation air)
are supplied to the space that requires air-conditioning.
Primary air
Induced air
The WAAB 600 has been designed so that it can be accessed easily for maintenance and servicing
operations. For this, it has 4 fastening hinges, which keep the internal frame in position. Thus, the
internal frame is collapsible over two axes, by simply moving the two hinges situated on the same face
as the internal frame. In this way, both the battery and the primary airflow regulating systems are
easily accessible for any necessary maintenance and adjustment operations Plus once the internaleasily accessible for any necessary maintenance and adjustment operations. Plus, once the internal
frame has been collapsed over one of its axes, the internal frame can be completely removed by
moving the two remaining hinges.
Once the internal frame of the WAAB 600 chilled beam has been released, the airflow can be adjusted
and the deflection angle changed.a d t e de ect o a g e c a ged

CONSTRUCTION AND WORKING SYSTEM WAAB 600
Airflow adjustment
The WAAB 600 chilled beam can be supplied with a primary airflow adjustment system. This
adjustment can be made using a tube wrench with a diameter of 8 mm, making it easy to select
between three air output configurations. Thus, even if the project specifications change, the primary
airflow can still be readjusted using the same installation.

The WAAB 600 chilled beam can be supplied with air deflectors situated over the internal frame. The
deflectors can be adjusted individually over a range of 0 to 45 º, permitting a wide variety of different
air diffusion configurations in the treated area.

Methodology
A chilled beam’s capacity consists of one part supplied by the primary air and a second
part supplied by the water.
The primary air rate can be calculated using the Graphs numbered with II It can likewise
P = Ppr + Pw,r
!#$ " '() * +#$ * ,-$#
The primary air rate can be calculated using the Graphs numbered with II. It can likewise
be calculated using the following equation:
Because of the chilled beams’ high capacity in heating mode, it is not necessary for the
primary air to supply additional heat. In these cases, the system usually works with a
discharge of isothermal air, that is, by discharging the primary air at the same temperature

as that in the premises (#tpr=0).
The technical data pertaining to each of the chilled beams are determined using the
following graphs. The graphs show that the water’s thermal capacity varies depending on
the water’s volume of flow. Thus, once we have defined the nominal thermal capacity (Pw),
we calculate the chilled beam’s working thermal capacity by applying the water flow
volume correction factor (Fw)

Selection example
Let us assume an office with dimensions 3x6x3 and cooling needs of 1800 W. The design
conditions are defined below:
6 m
Total ventilation level of 160 m3/h
Primary air temperature of 16ºC.
Interior room temperature of 26ºC.
Incoming water temperature of 16ºC.
Water flow volume of 140 l/h.
Maximum permissible noise level of 45 dB(A).

TECHNICAL DATA and METHODOLOGY WAAB 300
Calculation
1.- Firstly, we determine the primary airflow volume for each of the chilled beams. Using
Diagram IV on page 14, we select the type of nozzle depending on the maximum
permissible noise level.
Diagram IV: Nozzle KS $ mpr=80 m3/h $ LWA=41 dBA $ Pa = 178 Pag pr WA a
2.- The chilled beam’s nominal cooling capacity is determined based on the primary airflow
and the difference in temperature between the benchmark for the premises and the supply
water (#twa). To do this, we use diagrams V and VI.
Diagram V and VI: Nozzle KS $ mpr=80 m3/h $ #taw=26 -16 = 10 ºC $ Pw = 619,6 W
3.- Using diagram III, we calculate the modification factor of the airflow rate based on the
selected water flow volume. Likewise, we obtain the pressure drop in the water circuit.
