The Barcol-Air chilled beam systems are designed to achieve a comfortable indoor climate with low energy consumption and

a low ceiling void height. The systems provide cooling, heating, ventilation and humidity control with low noise and minimal

maintenance.

Introduction

Figure 1: KLIMA Active Chilled Beam

System Technology

Barcol-Air active chilled beams integrate the primary air distribution function with the secondary air heat exchange using a

proprietary air nozzle technology to induce secondary room air into the unit and through the heat exchanger before mixing

with the primary air. The resulting mixture of primary air and induced secondary room air is then supplied to the room through

the contoured diffusers which are designed to keep the air close to the ceiling using the Coanda effect.

Barcol-Air's KLIMA 2 600 series active chilled beams units are designed with a nominal width of 600 mm to integrate with the

ceiling grids of the more popular ceiling configurations. Standard unit lengths are nominally 1,200 mm to 3,000 mm in 300 mm

increments but special lengths are also available to match with specific ceiling requirements.

Rev 140910

The principle of the active chilled beam system is to use terminal chilled water heat exchangers in the ceiling to offset the

room sensible cooling loads or to provide sensible heating. The ventilation and humidity control requirements are taken care

of by using separate primary conditioned air supplied by a central air handling unit.

Due to the relatively high supply chilled water temperatures, about 16 deg C, the heat exchangers operate dry, avoiding many

of the maintenance and health concerns that are associated with other systems that use terminal heat exchangers such as

fan coil units.

The system provides large energy savings because the amount of air to be circulated around the building can be reduced to

close to that required for ventilation and humidity control only, resulting in large reductions in air handling unit fan power and

energy consumption.

Further energy savings result from the use of high chilled water temperatures serving the heat exchangers. This can allow the

water chiller to operate at higher water temperatures, giving the opportunity to improve chiller operating efficiency and

energy consumption.

Figure 4: KLIMA – Air Distribution

The specific shape of the supply slot diffusers creates two opposing discharge air flows from the active chilled beam along

the ceiling. The velocity of the supply air along the ceiling creates the Coanda-effect whereby velocity differences in the cool

air stream press the air stream against the ceiling, thereby extending the air throw and preventing the cool air from dropping

into the comfort zone prematurely. It is important, with such air patterns, that the ceiling is flat and free of any obstacles,

especially light fixtures situated close to the slots, because these can disturb the Coanda-effect.

Facade-orientation

Orientation of the active chilled beam with regard to the facade has no influence on the operation. There are two common

installation arrangements, perpendicular or parallel to the facade. The choice between perpendicular and parallel will be

Figur 7: High Efficiency Air Nozzles

Low Height:

The KLIMA 600 series has a maximum height of 200 mm allowing the use of reduced height ceiling voids to maximize ceiling

heights. Alternatively the building slab to slab height can be reduced allowing more floors in a given building height.

Flexible Sizes

Units are available with lengths between 1200 mm and 3000 mm to match with most ceiling configurations. Unit lengths can

also be tailored to match exact installation requirement.

Aesthetic Choices

The KLIMA 600 series can be supplied with perforated return air diffusers or linear slot diffusers to match the aesthetic

requirements of the building. Exposed metal surfaces are powder painted. The standard finish colour is RAL 9010 with 20%

gloss. Other RAL colours can be supplied to match project requirements.

Simple mounting:

Units can be easily suspended from the concrete slab above using threaded rod or hanging wire support systems to match

with metal panel, fiber board or plaster ceilings. Units can also be installed without ceilings.

High capacity with multi choice nozzles

The KLIMA 600 series active chilled beams have a choice of 8 nozzle configurations designed to provide high induction rates

for the secondary room air and thereby high cooling and heating capacities. This makes them suitable for application in a

building’s perimeter zones requiring higher cooling capacites as well as internal zones. Nozzles are factory installed and can

be blanked if one side discharge is required.

5Rev 140910

Low noise:

The efficiently shaped nozzles create maximum induction with low sound levels.

Low maintenance:

The KLIMA 600 series active chilled beam has no filter, fan, drain pan or any other moving parts and maintenance is limited to

cleaning the exposed metal surfaces and cleaning any dust from the heat exchanger every 2 to 5 years depending on the

cleanliness of the supply air. The heat exchanger can be easily accessed by dropping down the centre perforated diffuser

which is equipped with a safety hanging wires, and then removing any dust with a vacuum cleaner.

Controls:

The active chilled beam can be supplied with constant air volume controllers for the primary air, water control valves with room

control sensors as well as balancing and isolation valves and condensation sensors.

Air Distribution Control (Optional)

To allow selection of the air discharge pattern KLIMA 600 series units can be supplied with optional air discharge deflectors.

These air deflectors can be independently adjusted to provide different air distribution patterns.

Performance table notes1) Air cooling capacities are based on Troom minus T primary air = 10 deg C. For other conditions multiply the table air cooling capacity by the required (Troom minus Tprimary air) divided by 10. Alternatively the air cooling capacity can be calculated from the formula: Air cooling capacity W = 1.213 x Airflow (l/s) x (Troom minus T primary air)2) Water cooling capacities are based on Troom minus T entering water temperature = 10 deg C. For other conditions multiply the table water cooling capacity by the required (Troom minusT entering water) divided by 10.3) Water heating capacities are based on 4 pipe chilled beams with T room minus T entering water temperature = 35 deg C. For other conditions multiply the table water heating capacity by the required (Troom minusT entering water) divided by 35.

Selection example

Specified data:

Office (LxWxH) 7.2 (L) x 5.4 (W) x 2.7 (H) m

Occupants: 4

Minimum Ventilation 4 x 10 l/s = 40 l/s

Preferred size of chilled beams 1800 x 600 mm ( 2 units )

Summer room design condition ( Troom ) 24 deg C with 50% Relative Humidity (dew point 13.0 deg C)

Chilled Water temperature (Tw,in ) 15 deg C (Room Dew Point 13 deg C + 2 deg C)

Summer supply air temperature (T1 ) 12 deg C

Summer sensible room cooling load 2 700 W or 1350 W per chilled beam

Winter room design condition ( Troom ) 20 deg C with 50% Relative Humidity (dew point 9.0 deg C)

Heating water temperature (Tw,in ) 45 deg C

Winter supply air temperature (T1 ) 20 deg C

Winter heating requirement 2600 W or 1300 W per unit

Calculation:

The temperature differences required to make Determine required airflow for humidity control:

the cooling selection are: Room latent load = 4 people x 55W = 220W

ΔTAC = Troom - T1 = 24 – 12 = 12 deg C = 3.0 x Airflow l/s x ∆ humidity g/kg

ΔTWC = Troom - Tw,in = 24 -15 = 9 deg C Room condition 24 deg C 50% RH and humidity = 9.33 g/kg

The temperature differences required to make Supply air condition 12 deg C. Allow 1 deg C heat gain for

the heating selection are: AHU motor and duct heat gain so required off coil temp = 11

ΔTAH = T1 - Troom = 20 - 20 = 0 deg C deg C and with 98% RH and humidity = 8.03 g/kg

ΔTWH = Tw,in - Troom = 45 - 20 = 25 deg C Required primary airflow for humidity control

= 220 / [3.0 x(9.33 – 8.03)] = 56 l/s or 28 l/s per beam which is

more than the 40l/s or 20l/s per beam required for ventilation

Selection:

Model: Width: 600 mm

Length: 1800 mm

Performance table: Page 9

Primary airflow: 28 l/s per beam

Nozzle: B1

Static air pressure in plenum: 102 Pa

Cooling Performance

Available cooling from primary air: 1.213 x 28 x 12 = 407 W per unit

Required cooling from chilled water: 1350 – 407 = 943 W per unit

From page 9 select water cooling capacity: 1062 W per unit at ΔTWC = 10 deg C with water flow = 0.08 l/s

With ΔTWC = 9 deg C water cooling equals: 1062 x 9 deg C / 10 deg C = 956 W per unit

and water flow is: 0.08 l /s

water pressure drop is: 23.3 K pa

water temperature difference is: 956 W / ( 4.187 x 0.08 l/s x 1000) = 2.9 deg C

And total cooling capacity is: 407W + 956W = 1363W per unit x 2 units = 2726 W

This satisfies the total sensible cooling requirement of 2700 W for the room

Heating Performance

Available heating from primary air: 1.213 x 28 x 0 = 0 W per unit

Required heating from heating water: 1300 – 0 = 1300 W per unit

From page 9 select water heating capacity 1889 W per unit at ΔTWH = 35 deg C with water flow = 0.03 l/s

So water heating capacity for ΔTWC = 25 deg C 1889 x 25 deg C / 35 deg C = 1349 W per unit

and water flow is: 0.03 l /s

water pressure drop is: 0.9 K pa

water temperature difference is: 1349 W / ( 4.187 x 0.03 l/s x 1000) = 10.7 deg C

So total heating capacity is: 0W + 1349W = 1349 W x 2unit = 2698 W per unit

This satisfies the total sensible heating requirement of 2600 W

Guide Specifications

Barcol-Air KLIMA 600 series active chilled beams shall be used to compensate for the external and internal heat loads of the

building and shall maintain the thermal comfort in the room within the specified comfort and noise criteria.

Functional description

Primary air will be supplied by the fresh air handling unit to the chilled beam air plenum box. The primary air shall then

pass through the induction nozzles into the mixing section to mix with the induced room air before being distributed into the

room by two slot diffusers.

Induction nozzles shall induce air from the room through the inlet air diffuser and then through the fin and tube

cooling/heating heat exchanger before mixing with the primary air and being supplied to the room. The induction nozzles

shall be factory installed to provide the required unit capacity with the specified primary airflow, air inlet pressure and noise

level.

Heat exchangers shall be 2-pipe type for cooling only or cooling/heating changeover systems or 4 pipe type for systems

with separate cooling and heating circuits.

The units shall incorporate two linear slot air supply diffusers and shall be designed so that the supply air is discharged

horizontally under the ceiling using the “Coanda” effect to increase the air throw and to ensure the air mixing with the room air

above the occupied zone. The centre diffuser shall be perforated to allow the room air to flow in to the heat exchanger and

shall be easily removable to allow for any accumulated dust to be removed from the heat exchanger with a vacuum cleaner.

The centre diffuser shall be provided with safety hanging wires.

Construction of the chilled beam:

The primary air plenum box shall be manufactured from galvanized sheet steel and shall have one or more circular air

spigot connectors to ensure the inlet air velocity does not exceed 2.5 m/s. The plenum should be internally insulated to

prevent condensation if the primary supply air temperature is less than the surrounding air dew point temperature.

The nozzle plate and chilled beam body shall be manufactured from galvanized steel with a minimum thickness of 0.8mm.

The heat exchangers shall be made from seamless copper tubes with aluminum fins and shall have 12 or 15 mm diameter

water connections depending on unit's size and connections. The heat exchangers shall be suitable to operate at 15 bar

working pressure and shall be factory pressure tested at 20 bar pressure.

The supply air diffuser and room air inlet diffuser shall be manufactured from galvanized steel with a minimum thickness

of 1.0 mm and shall be finished with polyester powder paint to RAL9010 with 20% gloss or with an alternative finish to be

specified.

Dimensions

Width: The chilled beam shall be 595 mm wide.

Length: The units shall be 1200, 1500, 1800, 2400 and 3000 mm long or any intermediate length by special order.

Height: The height of the chilled beam (including distribution plenum) shall not be more than 200mm.

Installation

The chilled beam shall have 7 mm diameter mounting holes for suspension by 6mm diameter threaded rod or suspension

wires.
