––PRODUCT INFORMATION

Dadanco participates in the ECC programfor the full range of the active chilled beams.

02 | DADANCO | ACTIVE CHILLED BEAMS ACB46

ACB46 2-way active chilled beams incorporate new patented technologies to deliver a breakthrough for higher energy effi ciency perimeter and centre zone air conditioning using lower air quantities.

Dadanco active chilled beams are fully tested to EN15116 to provide effi cient, effective and whisper-quiet air conditioning for almost any application, delivered with comfort in mind in accordance with ISO7730:2005.

ACB46 incorporates 2-way supply air discharge with one

piece perforated return air grille and a single horizontal

secondary cooling coil.

By controlled air volume, pressure and nozzle confi guration,

the primary air generates a low pressure zone above the

cooling coil, inducing warm room air through the coil,

which cools, mixes with the primary air giving an output of

approximately 4 l/s through the air discharge slots below the

beam for every 1l/s of primary air from the main ductwork.

This combined air gently and quietly enters the space,

using the Coanda effect to travel across the ceiling before

diffusing into the occupied zone at low velocity.

ADVANTAGES OF ACTIVE CHILLED BEAMS• Supply cooling, heating and the outdoor air required

for ventilation in the conditioned space.

• Compact dimensions and intrinsically smaller duct sizes

than air based systems offer real savings in ceiling space

requirements for HVAC new construction and

refurbishment projects.

• Lower fan energy required – By effi cient use of the

secondary cooling using chilled water with far higher

thermal capacity than air as the cooling medium. The

quantity of conditioned primary air delivered at pressures

from 70-120Pa is far lower than all air based systems.

The primary air is typically only 25-30% of the total

air supplied by ACB46 units due to the use of effi cient

induction technology to recycle and cool room air.

• Secondary air is induced over the secondary heat

exchanger due to carefully controlled nozzle velocities,

delivering localized cooling driven by air volume/pressure

with no additional fan energy required.

• ACB46 active chilled beams provide 2-way supply air

distribution for perimeter or internal zone applications.

• ACB46 active chilled beams are designed for ‘Lay-In’

installation in ceiling tile systems or in plasterboard

ceilings with builders’ ceiling frames.

• ACB46 active chilled beams deliver more cooling capacity

using less treated air than any all-air system.

• Active chilled beams offer 2-stage capacity control

through control of secondary water fl ow separate from

primary air control.

• Noise radiated from Dadanco active chilled beams is

typically <40dB(A)

• Active chilled beams require minimal maintenance

(no moving parts).

TYPICAL ACB46 AIR DISTRIBUTION The 2-way discharge air fl ow characteristics of active

chilled beam ACB46, created by the induction of secondary

air through the centre of the unit. This produces a unique

air fl ow pattern resulting in thorough purging of air in the

occupied space compared to most conventional all-air

diffusion characteristics.

At an induction ratio of approximately 3:1, the mixed

primary air and cooled room air gently and quietly re-enters

the space by Coanda across the ceiling.

Low terminal air velocities are targeted for the occupied

zone of <0.25m/s to meet standard comfort criteria

specifi ed in ISO7730:2005.

NOTES

1. Nominal cooling capacities based on 24°C room air, 14°C primary air, 14°C entering secondary water temperature and secondary water fl ow rate to achieve best output at <20kPa coil pressure drop minimum water fl ow = 0.03 L/s.

2. Primary air volumes are limited to <25l/s/m of beam to offer high thermal comfort levels in accordance with ISO 7730:2005 PPD<15%. Higher air volumes will give higher cooling outputs but at elevated high draft risk exceeding 0.25m/s in the occupied zone, PPD>15%.

3. General application primary air pressure <125Pa.

4. Different performance results can be achieved for varying secondary water fl ow rates, entering water temperatures, primary air conditions and primary air pressures.

5. For selections at conditions and unit sizes other than those above please contact Reece HVAC for further assistance.

PATENT PROTECTED TECHNOLOGYDadanco Starline™ multi-lobe high performance induction

nozzles and superior fl uid dynamics design are combined

into the new ACB46 active chilled beams for improved

performance and lower noise characteristics.

Rather than relying on natural convection as with passive

chilled beams, ACB46 active chilled beams use primary

air to deliver ventilation air and induce secondary room

air through the secondary cooling coil within the unit.

This delivers an enhanced performance in either a ceiling

mounted package or a fully exposed, free hanging package.

EUROVENT APPROVED TEST FACILITYDadanco headquarters in Adelaide also offers the ability to

fully test and validate beam performance in their state of the

art test facility, to show performance in the specifi c design

conditions to be used at site.

Eurovent approvals confi rm the cooling outputs as per

the calculation tool; this additional testing is to show

performance within the design environment.

GUIDE SPECIFICATIONACB46

SCOPEProvide Dadanco 2-way discharge ACB46, ceiling integrated Active Chilled Beam units, fi tted with

low noise, high effi ciency patented STARLINE™ nozzles, with capacities as listed in the equipment

schedule. The confi guration of the units is shown on the drawings.

INSTALLATIONTo ensure the performance of the active chilled beam, allow for the following:

• Ensure the unit is mounted level and

secure from independent suspension

materials (by others). It must not be

supported from the ceiling system.

• Connect the main primary air duct

using a short length of fl exible

ductwork (not included), one size

larger than the 150mm diameter or

200mm diameter ovalised duct, as

straight as possible or with gentle

radius bends, make all joints air tight.

• If the air coil is equipped with four

pipe tails then connect the outer

pipes to the secondary chilled water

fl ow (CHW) and return piping (by

others).

• If required, connect the inner two

pipe tails to the heated water (HTW)

fl ow and return piping.

CONSTRUCTIONCasing to be from 0.8mm galvanised steel panels to provide

a compact unit with a primary air plenum, secondary air

cooling coil, 2 entrainment and discharge chambers and

mounting provision.

Plenum; Fit 2 rows of the specifi ed number and size of

STARLINE™ induction nozzles to the primary air plenum

to discharge into the air entrainment chambers. Provide a

round 150mm diameter / ovalised 200mm diameter sheet

metal spigot located centrally on the long side of the

primary air plenum, to permit connection of the primary air

Bradfl o™ fl exible ductwork to the unit plenum.

If primary air temperatures are selected below CBCA* limits

of 14°C (which is not recommended), plenum insulation is

available as a self-adhesive, fi re retardant thermal insulation

applied on the inside of the primary air plenum to prevent

condensation forming on the outer casing of the unit.

Nozzles; Fit multi lobed patented STARLINE™ induction

nozzles of pliable fi re retardant polymer, designed for low

noise generation and rapid secondary air entrainment.

Provide the number and size of nozzles required to provide

the primary airfl ow capacity for each unit as specifi ed, to

achieve the primary (airside) sensible cooling.

Secondary Cooling Coil; Fit a single 2 row (2 pipe or 4

pipe) secondary air cooling coil of the specifi ed length

as required to achieve the specifi ed sensible secondary

(waterside) cooling capacity. Coils shall be constructed of

galvanised steel end plates and frames, with ½” copper

tubes mechanically expanded into 0.145mm thickness

rippled edge aluminium fi ns. Provide either plain 12.7mm

copper tails or ½” BSP male fl at face tapered thread fi ttings

for CHW coil connections. Tails/fi ttings are to be in a vertical

arrangement to ensure no water pipes or connections

overhang the overall length and width dimension of the unit.

Pressure testing; Coil shall be factory pressure tested to

25 bar (2500kPa) with an advisory operating pressure of

16 bar (1600kPa).

Grille; Provide an integral powder coat satin white fi nished

dot perforated return air grille for each unit placed centrally

to form 2 linear discharge slots along each longitudinal side.

The grille is to be hinged on one side, retained on the other,

to allow the under plate to be swung down for coil cleaning

and access to the optional lint screen (if selected).

The unit shall incorporate a commissioning tube to measure

the static pressure in the plenum, made from fl exible clear

plastic tube, sealed air tight to the plenum casing and

accessible from below for commissioning purposes.

Lint Screen; If selected fi tted to the frame of the secondary

heat exchanger above the open able return air grille. This is

to be fabricated from fi ne plastic fi bre mesh secured onto a

rectangular aluminium extrusion frame. This is secured with

fi xing clips to the secondary coil frame.

HEALTHCARE ACTIVE CHILLED BEAMS - ACB46H

HINGED COILSuitable for use in non-invasive areas in healthcare applications, Dadanco have a sealed, closed case

solution with drop down battery feature to facilitate cleaning during the routine annual deep clean operations

seen in hospitals and other healthcare institutions.

For use in all areas except for invasive treatment rooms, active chilled beams are the obvious long life choice

for cooling, heating and ventilation requirements offering the best indoor comfort climate available at the point

where it is needed most.

Key Features

• Lowest energy consumption HVAC system

for Healthcare use.

• Low air velocities in the occupied zone.

• Whisper quiet operation.

• Sealed casing ensuring no uncontrolled void

air contamination into the space below.

• Drop down battery feature for cleaning;

EXPOSED CEILINGSAdjustable air distribution vanes

Under certain circumstances it is desirable to be able

to adjust the airfl ow distribution pattern to achieve even

higher levels of indoor thermal comfort and reduce draft

risks in the occupied zone below the beams.

Offering standard “long” throw bullet shape airfl ow profi le,

the Dadanco offer can be used to widely disperse both

cooling primary air and mixed secondary cooled room air

induced through the fi ncoil battery.

By fi tting adjustable vanes this pattern can be shortened

in length and push the air distribution wider, keeping

the primary air and conditioned room air locally within

the space below the ACB46 unit. This is important where

beams are placed in close proximity to each other at 3m

centres to avoid colliding air paths from two adjacent

ACB units.

Depending on the design condition, this can marginally

reduce the induction ratio with a very minor reduction in

the secondary cooling output. The effect of which should

be considered whilst selecting beams against the cooling

duty required for the space.

Key Features

• Provide divergent air fl ows locally around the ACB unit.

• Reduce the chance for colliding air paths and give

resulting lower air velocities in the occupied zone.

• Maintain a whisper quiet operation.

• Offer a degree of adjustability in service if different air

fl ow patterns/ effects are required.

PRIMARY AIRThe primary air cooling chart is based on specifi c heat cooling potential of ducted

conditioned air. The standard technical data tables use 8 and 10°K reductions for

the supply air and water temperatures.

To determine the sensible cooling capacity multiply required fl ow rate by cooling

energy as determined on the chart y-axis.

If the primary air dew point temperature is available and assuming the room air

condition is 24°C, 50%RH the second chart indicates the available latent cooling.

CLIMATIC TESTING FACILITY

Australia’s only “Scenario Analysis Facility”, state of the art Climatic Test Laboratories

are the fl agship of Dadanco R&D Technical Centre based in Salisbury, SA.

Capable of Project Specifi c Testing including:

• Thermal Capacity Validation in accordance with

EN15116:2008

• Project specifi c testing for occupied zone thermal

comfort parameters according to ISO7730:2005.

• Solar heat gains including corner offi ce simulation

(having 2 radiant walls).

• Perimeter zone up to (and exceeding) 170W/m2.

• Centre zone 35-75W/m2 using Din men “thermal

mannequins”.

• Thermal and air velocity topographies at

- 1.8m AFFL

- 0.8m AFFL (working plane)

- 0.2m AFFL

• Smoke visualisation testing.

• Acoustic data collection.

This provides a local key tool for Consultant Engineers to model space behaviour under strictly

controlled conditions prior to any site installation, assisting to refi ne designs and avoid poor thermal

comfort problems occurring at site once the building is fully occupied.
