Introduction

The AIR-FIT® : creating a comfortable indoor climate with minimal energy usage and low installation space.The active chilled beam has been developed for mixed HVAC systems where the air handling installation sup-plies necessary ventilation air, while cooling and heating energy is mainly transported by water. As a result the air handling unit and duct work can be limited.The height makes the AIR-FIT® most suitable for projects with limited space above the false ceiling, like retrofit projects. This application can lead to a lower gross floor height in case of new building constructions.

System technology

The system technology is based on the venturi effect of the special shaped nozzles causing induction of room air into the primary airflow through a cooling and/or reheat coil.

The conditioned air from the central air handling unit will be injected by the nozzles into the mixing section of the unit. The room air directly beneath the unit will be guided through a perforated plate and heat exchanger. The mix-ture of conditioned primary air and heated or cooled room air will be transported along the ceiling by two integrated slot diffusers.

Relatively large room air quantities are being guided through the heat exchanger by this induction technology. A small difference between supply water temperature and room air temperature will do. This will prevent condensa-tion during cooling mode.

Application area

The active chilled beam is highly recommended for of-fices. Two ventilation air changes will do for standard office spaces (occupation 8 to 10 m2 per person). With this primary air volume, sufficient air will be induced to compensate the typical sensible cooling load of approxi-mately 50 W/m2.Even (usually limited because of well insulated buildings) when heating is needed ventilation in winter time will be no problem for the ceiling-induction-units. Generally meeting rooms need more ventilation air than offices. This can be achieved by using multiple and/or larger mo-dels. However with more than 5 air changes (circulation) per hour, the risk of draught increases. In that case we recommend a different solution.

Application for meeting rooms

Realization of a comfortable indoor climate needs extra attention. This will be illustrated in the next example.

We assume a meeting room with following dimensions: L x W x H = 6.0 x 3.6 x 2.7 m (total volume of 58 m3). Based on a maximum occupation of 12 persons and a minimum fresh air flow of 30 m3/h, primary air flow will be 360 m3/h. With an induction factor of only 2, there will be 720 m3/h supplied into the room. This results in 12 air changes (circulation) per hour. When covering cooling and heating load, there will be no problem; however the room air supply principle of the active chilled beam (compared to well operating slot dif-fusers) is not suitable for 12 air changes (circulation) per hour.In this case we recommend use high performance diffu-sers combined with one of our conventional systems.

In this document, different system applications are des-cribed. The system on page 27 combines active chilled beams in offices, with fan coil unit systems in meeting rooms. In these cases it will not be necessary to adjust the overall system.For non standard applications and/or selections, please contact our technical staff.

Air distribution in the room

The specific shape of the supply slot diffusers create two, opposite air patterns from the active chilled beam along the suspended ceiling. These air patterns provide good distribution of supply air into the room. The velocity of the supply air along the suspended ceiling creates the Coanda-effect; velocity differences in the cool air stream will press this air stream against the suspended ceiling, thus preventing to enter the comfort zone prematurely.

It is important, with similar air patterns, that the suspen-ded ceiling is flat and free of any obstacles. Especially when light fixtures are situated close to the slots, where they can influence the necessary Coanda-effect.

Facade-orientation

Together with the earlier mentioned aspects, orientation of the active chilled beam with regard to the facade has no influence on the operation.

There are two different applications for the active chilled beam in offices with regard to the facade: perpendicular or parallel to the facade.The choice between perpendicular and parallel to the facade will be determined by:

• Aesthetics (fitting into the pattern of the suspended cei-ling)

• Level of flexibility to create offices within the floor plan• Number of active chilled beams (purchase and installa-

tion)• Available distance for the throw; the air must have the

opportunity to mix before it reaches the comfort zone• Disturbances in suspended ceiling which might influ-

ence air pattern, like lighting armatures• Disturbances in the facade or floor, like radiators or floor

convectors, that might influence the air pattern

Features of the AIR-FIT® active chilled beam

High capacity:The active chilled beam has a high cooling and heating capacity and is suitable to ventilate, to cool and to heat (mainly) offices.

Compact in size:With a ceiling area of only 1500 x 300 mm, 10 m2 is sup-plied with sufficient ventilation air, cooling and heating. Furthermore the active chilled beam is relative low in weight and needs minimal installation space. No extra diffusers are needed.

Simplicity in mounting:With a width of 295 or 595 mm, the active chilled beam can perfectly be integrated into suspended ceilings with T-bars or metal ceiling systems for intermediate moun-ting.

Multi-nozzle technology:The active chilled beam is provided with three nozzle positions. The primary air volume of every single unit can easily be adjusted, even after mounting into the suspended ceiling.

Low noise:The efficiently shaped nozzles create maximum induc-tion at minimum sound level.

Low maintenance:The active chilled beam has no filter, no fan or other mo-ving parts, so maintenance is limited to clean the heat exchanger every now and then. The heat exchanger can be accessed simply by removing the perforated front, which is equipped with a safety catch.

Controls:The active chilled beam can be controlled in many diffe-rent ways. HC Barcol-Air Controls Division can provide a solution for every (integrated) application.

Facade orientation:The active chilled beam will supply air into the room through 2 opposite slots. In office applications the unit can be located in the middle of the room, either perpen-dicular or parallel to the facade.

Flexibility:The active chilled beam is available in different width and lengths. Project specific requirements are possible for reasonable quantity (upon request). This makes the AIR-FIT® suitable for almost every suspended ceiling.

Installation, Maintenance & Cleaning

Installation

There are multiple solutions for fitting the AIR-FIT® active chilled beam.

“lay-in” on T-barsThe units with size 295 or 595 mm are suitable for fitting into a suspended ceiling (T-bar) with a centre to centre size of 300 or 600 mm.Identical sizes need to be applied for fitting into a plaste-red or any other closed ceiling by using L- or T-bars.

“Fixed” to building constructionThe short sides of the units are equipped with 6 mm diameter mounting holes. These mounting holes can be used to attach the unit to the concrete ceiling.The mounting holes can also (additionally) be used in combination with the inlay method (security reasons).

Duct connectionThe active chilled beam is equipped with 1 or 2 circular spigots for duct connections. In case of 2 spigots on one unit, we recommend a symmetric connection by using equal connecting lengths or a T-connection.

Coil connectionThe heat exchanger is equipped with multiple (separate) circuits for heating and cooling (4-pipe system). Connec-tions are made of copper. The cooling and heating cir-cuits are indicated by blue respectively red marks.For further information we refer to page 20.

Connection can be executed by pressed or solder connection. We recommend to use flexible hoses with Eurotek quick-lock connectors which can be supplied as an accessory. (see page 20 and 29)

Maintenance & Cleaning

The perforated screen needs to be removed to clean the heat exchanger and/or nozzles. To remove the perforated screen, following instructions must be followed:

Step 1: Push the perforated screen upward, close to one of the end caps.

Step 2: Push simultaneously the whole panel aside in a linear direction to the end cap as mentioned in step 1.

Step 3: By this movement the perforated screen on the other side can now be removed. The panel will still be connected to the active chilled beam by two safety catches.

Refitting the perforated screen is done in reverse order.

The AIR-FIT® active chilled beams are equipped with multi-nozzle technology.

The AIR-FIT® multi-nozzle technology consists of three nozzle groups on both sides with different diameters. The position (1, 2 or 3) of the nozzle can be adjusted. At constant static pressure, the primary airflow can be changed.

Multi-nozzle technology

Adjusting multi-nozzles

The only tool needed to adjust the multi-nozzle is a Philips head screwdriver.

Step 1: Remove the perforated screen (see page 18).

Step 2: Unscrew all screws from the sliding plate. (1 full turn)

Step 3: Move the sliding plate into the desired position.*

Step 4: Tighten all screws (hand tight).

Step 5: Replace the perforated screen.

*Factory setting: nozzle position 2.

Applications, system A:Mechanical ventilation with analogue temperature control

Active chilled beam, suitable for cooling and heating of-fice spaces.

The amount of fresh air is controlled by a manual setting on mechanical air dampers. The temperature is control-led by a simple 230 V AC analogue control thermostat.

The actuators for the cooling and heating valves are connected to the 230 V AC thermostats. The set point room temperature is controlled by opening or closing the valves. The dead zone between heating and cooling is 2 K.

Application in meeting rooms

Meeting rooms (as shown in the drawings) need more ventilation air than office spaces. This can be accomplis-hed by applying multiple and/or larger models.More than 5 air changes (circulation) per hour may increase the risk of draught. In that case we recommend a different approach, system D (see page 27) can offer a possible solution in this situation.

Features

• Manually set primary airflow.• Analogue thermostat for cooling and heating.

Advantages

• Easy to install.• Simplified control adjustment.• Limited number of components. Important notes

• Every unit must be manually commissioned on air vo-lume.

• Adjustment of primary airflow afterwards is time consu-ming.

• The system is pressure dependent. Therefore the performance depends on accuracy of the air sided com-missioning.

• Fixed dead zone between cooling and heating.• Stand alone operation.• Based on 230 V AC.

Active chilled beams for cooling and heating offices and fan coil units with high performance diffusers for cooling, heating and CO2 control in meeting rooms.

System D is identical to earlier described system C in relation to offices.

Application at meeting rooms

The amount of ventilation air is based on the CO2 level controlled by a DDC controller equipped with a high ac-curate air volume measurement device. As a result, air volume will regulate between a minimum and maximum air value. The maximum value corresponds with the maximum number of people in the meeting room. The fresh air supply is connected to the inlet plenum of the fan coil unit.

With the same digital controller the room temperature set point is controlled while the fan coil runs at a constant speed. The actuators for the cooling en heating valves are connected to the controller. The room temperature is measured by a temperature sensor with digital display. The room temperature set point is controlled by opening or closing the valves. The dead zone between heating and cooling is 1 K.

Features

• Digital volume controller with very accurate air volume control.

• User interface with digital display and override push button.

• Suitable for Building Management Systems.• The meeting rooms are CO2 controlled. Advantages

• Simply to complement with a relative humidity control ler at low costs.

• Volume and temperature control in one.• Accurate air volume control (Flo-cross® and DDC con

troller).• DDC controller (free programmable).• Digital temperature sensor (user interface).• Network possibility (LonMark® or BACnet®) easy to

connect with primary installation (BMS).• Adjustable dead zone by HC Barcol-Air control

engineers.• Different possibilities for energy reduction like occu-

pancy detection, light and daylight control.• No need to commission the air volume manually. • 24 V AC operation.• No extra components needed for master/slave control.• Adjusting parameters could be done from a distance

(Internet). Considerations

• More components needed as earlier mentioned systems (A & B & C).
