WAAB 600A ti hill d b idth 600Active chilled beam – width 600

MADEL!

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.

ASSEMBLY WAAB 600

Th WAAB 600 hill d b i t i f ti l b k t b th idThe WAAB 600 chilled beam incorporates a series of mounting angle brackets on both sides.

These brackets have an 18-mm long slot, so that the chilled beam can be easily mounted in the

installation. The number of brackets available varies depending on the nominal length of the

selected chilled beam; 4 for LN ! 1800 mm and 8 for LN " 2100 mm. The unit should be

suspended from the structure with officially approved steel supports, cables or rods. Once

suspended, the primary air duct should be connected to the plenum’s neck. Likewise, the battery

should be connected with solid elements, welding or quick connect fittings. Check that the

hydraulic circuit has been properly emptied and that the beam is properly connected to the

ventilation system to prevent air leaksventilation system to prevent air leaks.

TECHNICAL DATA and METHODOLOGY WAAB 600

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

!& $ " !& * .&

g y g g p y p

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:

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.

Diagram III: mw = 140 l/h $ Fw=1,1 $ Pw,r = Pw*Fw = 619,6*1,1 = 681,7 W

Diagram III: mw = 140 l/h $ #Pw = 3,41 kPa

4.- Finally, we calculate the airflow rate using diagram II.

Diagram II: mpr=80 m3/h $ #tpr=26 -16 = 10 ºC $ Pa = 273,1 W

5.- Thus, the total power provided by each of the chilled beams would be

P=Ppr+Pw =681,7 + 273,1 = 954,8 W

6.- Now we know the selected water flow and rate, we can determine the thermal gradient

of the water.

Diagram I: mw = 140 l/h $ Pw=681,7 $ #tw = 4,19 ºC

7.- Finally, we calculate the air range values based on the diagrams of aerodynamic data

of the WAAB 600x1500 beam.

Range to wall (VL):

H1= H - 1.8 m = 3 – 1,8 m = 1,2 m3mpr= 80 m3/h $ Nozzle P $ L = H1 + X =1,2 + 1,5 = 2,7 m $VL = 0.37 m/s

Thus, we obtain a speed of 0,37 m/s in the living areas

Range between beams (VH1):

H1= H - 1.8 m = 3 – 1,8 m = 1,2 m

mpr= 80 m3/h $ Nozzle P $ B = 3 m$ H1 = 1,2 m$ VH1=0.26 m/s

11 01/14

Thus, we obtain a speed of 0,26 m/s in the living areas.
