Function

The Halton Rex REE unit is an active chilled beam for exposed installation.

The primary supply air enters the plenum of the active chilled beam, from which it is diffused into the room through nozzles and supply slots on the top of the beam. The supply air nozzle jets efficiently induce ambient room air through the heat exchanger, where it is either cooled or heated. The supply air jet is directed horizontally along the ceiling surface. The recommended minimum distance is 600 mm from the wall and 100 mm from the ceiling.

Supply air can be additionally discharged upwards towards the ceiling via the diffuser of Halton Air Quality control located on the top at the rear end of the chilled beam.
 

Velocity control in the occupied zone

Halton Velocity Control (HVC) is used for adjusting room air velocity conditions either when room layout is changed (e.g., in cases where the chilled beam is located near the partition wall) or when local, individual velocity conditions need to be altered. Halton velocity control adjustment has an impact on the induced room airflow through the heat exchanger, and therefore it either increases or decreases both the velocities in the occupied zone and the cooling/heating capacity of the chilled beam.

Halton Velocity Control involves manual velocity adjustment with three different positions (Fig.1. and 2.): 1 = Throttle, 2 = Normal, and 3 = Boost. The Halton velocity control system is divided into sections to enable the adjustment of conditions in different parts of the occupied zone. Depending on the length of the beam, optimal HVC damper module lengths between 500 and 1400 mm are used.

It is recommended to design the chilled beam in the normal position in order to allow both throttle and boost functions during the building s life cycle.

Pos. 1 = Throttle position      Pos. 2 = Normal position       Pos. 3 = Boost position

Pos. 1 = Throttle position  / Pos. 2 = Normal position / Pos. 3 = Boost position

Airflow adjustment and control

The supply airflow of the chilled beam nozzle jets is dependent on effective length, nozzle type and static chamber pressure, which can be adjusted e.g. by using an airflow adjustment damper (e.g. Halton PTS).

Optional Halton Air Quality (HAQ) control is used for adjusting and/or controlling additional supply airflow rate in a room space. The airflow is dependent on the opening position of the control damper and the static chamber pressure.
Halton Air Quality (HAQ)


Fig.3.  Motorised control damper (HAQ)

Airflow rate control is needed when either room layout or the use of the space is changed (e.g., in a change from office to meeting room). Airflow rate can be adjusted either manually or via automatic demand-based control via a motorised control damper (Fig.3.). The actuator can be controlled by a room controller (not included) using a  0-10-VDC control signal.

A chilled beam equipped with HAQ manual airflow rate adjustment can be retrofitted into motorised demand-based control simply by replacing the HAQ-unit model and connecting the power supply and control signal from a room controller to the actuator.

The chilled beams are recommended to be connected to constant pressure ductwork zone, when

  • the HAQ adjustment has no impact on nozzle jet airflow
  • the HAQ adjustment has no impact on either the coil cooling or heating capacities
  • the HAQ airflow control has not significant impact to ductwork pressure conditions and respectively to airflow rates of other chilled beams in the same ductwork zone.

Demand-based air quality control and room air temperature control can be realised separately.

The appearance of different units – with constant, adjustable, or variable airflow – is identical.

The Halton Air Quality control unit s position and the selection of the chilled beam nozzle size allow adjustment of the primary airflow rate in the space. Airflow adjustment damper (e.g. Halton PTS) can be used for balancing the airflow.

When a motorised air quality control (HAQ) unit is used, the maximum and minimum airflow rates are adjusted with the stroke limiters of the damper. The airflow adjustment damper (e.g. Halton PTS) is not recommended for use in balancing the airflow in this case.

Five different nozzle sizes are available, to enable attaining the minimum supply airflow rate of the chilled beam in a typical room module. Typically, units that are similar (in length or nozzle type) allow effective commissioning of the system.

The primary airflow rate of each beam is adjusted using the Halton Air Quality control unit during the installation and commissioning. There is no need to change or plug nozzles of the chilled beam.

Halton Air Quality control also allows increasing the airflow rate of a chilled beam e.g., to meet the ventilation requirements of meeting rooms (up to 4 l/s per m², below 35 dB(A)).

Controlling of the airflow can be based on CO2 level. Alternatively, both air and water flow can be controlled based on temperature in two sequences. In that case the air flow rate will be modulated in the first sequence, and if the temperature exceeds the chosen set point, water valve will start to open.

Cooling and heating capacity control

The chilled beam can be equipped in the factory with either a adjustable kv control valve (RA-C) or a pressure independent valve (AB-QM). AB-QM has an adjustable maximum limit for the water flow rate and there is a pressure difference measurement for ensuring that the pressure difference (min. 16 kPa) is sufficient for proper operation. Both control valves can be equipped with a thermal on/off-actuator. See the section Accessories for further information.

In heating mode, it is recommended that the temperature difference between the jet outlet and room air would not be greater than 3 °C. The inlet water temperature of the heat exchanger should not be higher than 35 °C. Optimal heating performance requires an appropriate primary air flow rate. Thus, the air handling unit shall be in operation during heating periods to ensure proper heating performance.

Cooling and heating water valve selection in Halton Workplace WRA room automation system package

Water valve selection is done in Halton Workplace WRA room automation system package. Water valve sizing depends on the number of secondary and primary chilled beam units that are controlled with single controller. One water valve is used to control the whole chilled beam group cooling or heating operated by one room controller. Water valve is sized for whole group when there are multiple chilled beams controlled with single controller unit. There can be one primary chilled beam with room controller and up to three secondary chilled beams. Water valve sizing for 1-4 chilled beams is shown below.

Installation

The Halton Rex REE unit is suitable for exposed installation in the ceiling, typically lengthwise in the room. It is recommended to position the beam no closer than 600 mm from the wall and 100 mm from the ceiling. The chilled beam ceiling brackets can be fixed directly to the ceiling surface or suspended using threaded drop rods (8 mm). It is recommended that the brackets are positioned one quarter of a unit length (L/4) away from the end of the beam.

Install the main pipelines of the cooling and heating water loops above the level of the chilled beams to enable venting of the pipework.

Adjustment

Cooling

The recommended cooling water mass flow rate is 0.02 … 0.10 kg/s, resulting in a temperature rise of 1 … 4 °C in the heat exchanger. To avoid condensation, the recommended inlet water temperature of the heat exchanger is 14 … 16 °C.

Heating

The recommended heating water mass flow rate is 0.01 … 0.04 kg/s, resulting in a temperature drop of 5 … 15 °C in the heat exchanger. The maximum recommended temperature of the inlet water for the heat exchanger is 35 … 45 °C.

Balancing and control of water flow rates

Balance the water flow rates of the Halton Rex REE chilled beam with the RA-C control valve by selecting the designed kv value in the valve body.
When using an automatically balancing combination valve AB-QM, set the designed water flow rate in the valve body and verify the pressure difference (min.7.5 kPa) between the measurement nipples of the valve. The pressure difference over the valve must be 16 kPa, to ensure proper operation.
The cooling and heating capacity of the chilled beam are controlled by regulating the water mass flow rate.

Adjustment of supply airflow rate

Each Halton Rex REE chilled beam is equipped with a measurement tap for static pressure measurement, which enables fast and accurate measurement of the supply airflow rate through the effective part of the beam. The airflow rate is calculated using the formulas below:

Total airflow rate (qv)

qv        Total airflow rate, l/s or m3/h
qv1      Nozzle jet airflow rate, l/s or m3/h
qv2      Air quality control diffuser airflow rate, l/s or m3/h

Nozzle jet airflow rate  (qv1)

l eff          Length of the coil [m]
Δpm      Measured static chamber pressure [Pa]

Nozzle k (l/s) k (m3/h)
A 0.71 2.56
B 0,99 3,56
C 1,36 4,90
D 2.09 7,52
E 3,33 11,99

The supply airflow rate of the Halton Air Quality control unit is determined by measuring Halton Rex REE chilled beam static pressure and reading the opening position of the HAQ unit. The airflow rate is calculated using the formula below.
Air quality control diffuser airflow rate  (qv2)

                 HAQ position
Δpm             Measured static chamber pressure [Pa]

k (l/s) k (m3/h)

Adjustment of the airflow in constant airflow applications

Manual Halton Air Quality (HAQ)

Define the position of HAQ in millimetres that correspond to airflow rate at the actual chamber pressure level.

Adjustment of HAQ is done manually with the help of position scale by adjusting the opening of the unit. It is possible to verify the opening in millimetres on the position scale.

In order to ensure accurate adjustment it is recommended to adjust HAQ-position and in the same time read the targeted chamber pressure using a manometer.

Adjustment of the airflow range in variable airflow applications

Motorised Halton Air Quality (HAQ)

Key
1.  Release of the actuator
2.  Restriction of the max. opening
3.  Restriction of the min. opening
4.  Knurled head screw (2 pcs)

Switch-off the power supply of the actuator.

Disengage the actuator gear into manual override position by releasing the knob.

Define the maximum and minimum positions, in millimetres that correspond to maximum and minimum airflow rates at the actual chamber pressure level.
The maximum and minimum positions are adjusted with two hexagonal socket set screws (see image above, points 2 and 3). It is possible to verify the opening in millimetres on the position scale.

Switch on the power supply (24 VAC) of the actuator. The actuator calibrates the min. and max. positions automatically according to the set limits.

The actuator can be controlled from this point on by using a 0…10VDC control signal. (0 VDC = min.position, 10 VDC = max. position).

Clean the supply air plenum, duct, and finned coils of the heat exchanger using a vacuum cleaner, taking care not to damage the finned coils. Clean the front panel and, if necessary, the side plates with a damp cloth.

Open the access panel, and check at regular intervals that the airflow adjustment damper (if applicable) and water flow control valves are working.

The air quality control (HAQ) damper actuator can be accessed from on top of the chilled beam for service, if required.

Specification

The unit is an active chilled beam for exposed installation with bi-directional air supply.
The front panel is openable and detachable from either side without any special tools.

The chilled beam is 414 mm wide and 182 mm high, with inlet duct diameter of 125 mm.

The chilled beam can be equipped with a duct cover to cover the connection duct and pipe installations (optional).

The front panel and side panels are made of pre-painted galvanised steel plate (white, RAL 9003 or RAL 9010, 20% gloss).
All visible parts can be painted with special colours (RAL xxxx).

The primary airflow rate is adjustable over a wide range via a separate supply air unit of the chilled beam. Adjustment of the airflow rate does not have any effect on induced airflow rate through the coil. The induced room airflow rate is manually adjustable to three positions without influencing the primary air supply flow rate.

Supply airflow rate is manually adjustable using an airflow damper, or equipped with an actuator for demand-based control of the airflow (optional).
Control of supply airflow rate does not have any effect on coil cooling and heating capacities.
The adjustable airflow rate beam has only one duct connection.
The appearance of the chilled beams with constant airflow and adjustable airflow rate is the same.

The chilled beam can be equipped with a cable tray (optional).

All pipes are manufactured from copper, connection pipes with a wall thickness of 0.9-1.0 mm. The cooling heat exchanger consists of six 15 mm pipes connected in series. The fins of the heat exchanger are manufactured from aluminium. Heating is incorporated within the heat exchanger via two 10 mm pipes connected in series. All joints are factory pressure-tested.

The maximum operating pressure of the pipework is 1.0 MPa @ 70 °C.
Each chilled beam is protected by removable plastic coating. Duct connection and pipe ends are sealed for transit.
Each chilled beam is identifiable by a serial number printed on a label attached to the chilled beam.
