Introduction

CBQ

Multiservice chilled beam platform for suspended installation

Factory-fitted and tested CBQ-units are supplied to site as a single-fix device satisfying comfort cooling, heating and lighting needs. Options of the finish and equipment allow the CBQ to be customized to meet the aesthetic and engineering requirements of the site. Options, which can be factory fitted and tested, include:
 

  • Temperature, occupancy and illuminance sensors
  • Smoke detector
  • Lighting
  • Space for sprinkler pipes and nozzles
  • Public address speakers
  • Cables and cable tray for power & control wiring
  • Primary air and Halton Air Quality (HAQ) control dampers
  • Chilled water and LTHW control/isolation valves
  • Room controller

Halton provides a complete chilled beam design/ selection support service – cooling, heating and lighting plots, including emergency lighting and thermodynamic performance and velocity.

The CBQ is ideally suited to those buildings with reduced floor-to-ceiling heights as they allow the full height of the space to be realized between beams (no suspended ceilings).

For longer multiple beam module installations, chilled beams are supplied as a coordinated "plug and play" system with primary air plenums being connected together, avoiding the need to run separate ducts to second, third or possibly fourth beams. Luminaires are daisy chained so that only one power/control cable is required for a multiple chilled beam module installation.

Function

FUNCTION

The CBQ 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 the Halton Air Quality control unit located between the two plenum chambers.

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 air flow 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.

Airflow adjustment and control
The supply air flow of the chilled beam nozzle jets is dependent on effective length, nozzle type and static chamber pressure.

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

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. The actuator can be controlled by a room controller (not included) using a 10-VDC control signal.

A chilled beam equipped with HAQ manual air flow 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 air flow - is identical.

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

When a motorised air quality control (HAQ) unit is used, the maximum and minimum air flow rates are adjusted with the stroke limiters of the damper. Separate duct installed air flow adjustment dampers (PTS) is not recommended for use in balancing air flow in this case.

Four different nozzle sizes are available, to enable attaining the minimum supply air flow 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 air flow 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 air flow 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).

Air quality and temperature control
Air quality control of a room space can be arranged, e.g., using a CO2 sensor when room air temperature is controlled separately by regulating the water flow rate. Alternatively, a temperature sensor can be used for air quality control when air flow rate can be modulated in the first sequence and the water valve starts to open in the second sequence if the temperature exceeds the set point.

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 capacity control
The chilled beam can be equipped in the factory with either a standard control valve or a combination control valve. Both control valves are operated by a thermal actuator applying the on/off operation principle.

The standard control valve has an adjustable kv-value. The combination control valve 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. See Document-section for more information.

It is also possible to install the valves behind the duct cover at the building site.

Lighting

LIGHTING

Luminaires for CBQ chilled beams are especially designed high specification recessed direct/indirect luminaires for office applications. The luminaire is designed to suit chilled beam aperture, providing direct/indirect lighting to help meet the Office Lighting Guide LG7 (UK) requirements. Lights are installed and tested in the factory. An extra cable with or without plug is delivered upon request. Standard plug types are Schuko, Enstonet and Wieland.

Lights are manufactured from steel, power coated to match the required finish. Xenoptic satin louver is retained by shootbolt spring fixings. All luminaires come complete with T5 triphosphor lamps with the option of high output or high efficiency.

High frequency control gear DSI, DALI or 1…10 volt dimmable gears are available.

As an option there is also available self-contained emergency lights or central battery/static inverter conversions available, with or without self test system.

Installation

Installation

The Halton CBQ 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 ( 1050 mm between wall and unit centreline) and 100 mm from the ceiling using threaded drop rods (8 mm).

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

Connection of motorised air quality (HAQ) control:
Power supply: 24 VAC.
Control signal: 0 ... 10 VDC.

Luminaires
The luminaires within a single chilled beam are interconnected in the factory as standard. The power supply is connected using a plug connector located at the connection end of the beam. An extra cable with or without plug is delivered upon request. Standard plug types are Schuko, Enstonet and Wieland.

Adjustment

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 inlet water temperature of the heat exchanger should not be higher than 35 °C.

Balancing and control of water flow rates
Balance the water flow rates of the chilled beam with adjustment valves installed on the outlet side of the cooling and heating water loops. The cooling capacity and heating capacity of the chilled beam are controlled by regulating the water mass flow rate. The water mass flow rate can be controlled by using an ON/OFF valve or a two- or three-way proportional valve.

Adjustment of supply air flow rate
Each chilled beam is equipped with a measurement taps (2 pcs) for static pressure measurement, which enables fast and accurate measurement of the supply airflow rate through the effective part of the chilled beam. The airflow rate is calculated using the formula below.

Nozzle jet airflow rate qv1

leff = length of the coil, m

qv = qv1 + qv2

Adjustment of the air flow in constant airflow applications
Define the position of HAQ in millimeters 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 millimeters 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 the manometer.

It is also possible to remove the HAQ-unit from the frame by opening two knurled-head screws (4) for the adjustment.

2. Restriction of the max. opening
3. Restriction of the min. opening

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 millimeters that correspond to maximum and minimum air flow rates at the actual chamber pressure level. The maximum and minimum positions are adjusted with two screws (2,3). It is possible to verify the opening in millimeters 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...10 VDC control signal. (0 VDC=min.position, 10 VDC = max. position).

It is also possible to remove the HAQ-unit from the frame by opening two knurled-head screws (4) for the adjustment.

Adjustment of Halton Velocity Control
The Halton Velocity Control unit is adjusted by manually turning the sections of the unit.
The HVC units have three different positions: 1 = throttle position, 2 = normal position, and 3 = boost position.
