Exhaust valve integration

The Halton Rex 600 chilled beam can be equipped with an integrated exhaust valve, providing air supply and exhaust in the same unit. The integrated exhaust valve decreases the effective length to total length 500 mm (L - 500 mm) (for standard chilled beam L-300).

Function

The Halton Rex 600 chilled beam is designed to be installed flush with a suspended ceiling.

The primary supply air enters the plenum of the active chilled beam. From there it is diffused into the room through nozzles and the diffuser of the HAQ- control. Supply slots located at the bottom of the beam.

The supply air nozzle jets efficiently induce ambient room air. The induced air flows through the heat exchanger, where it is either cooled or heated.
The supply air jet is directed horizontally along the ceiling surface.

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 partition wall is located near the chilled beam) or when local, individual velocity conditions need to be altered. HVC 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.


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

The HVC damper is divided into sections (Pos.1-3) to enable the adjustment of conditions in different parts of the occupied zone.

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.

Airflow rate control

The supply air flow of the chilled beam nozzle jets are dependent on effective length and static chamber pressure, which can be adjusted e.g. using separate airflow adjustment damper.

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

Air flow rate adjustment is needed when the use of the space is changed and there is need to adapt the supply airflows. Air flow rate can be adjusted either manually or automatically, on the basis of demand, with a motorised control damper.

A chilled beam equipped with HAQ manual air flow rate adjustment can be retrofitted to motorised version for demand based ventilation.

It is recommended that chilled beams for demand based airflows should 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.

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 separate air flow adjustment damper installed in the duct branch ois used for balancing the air flows in the ductwork.
When a motorized air quality control (HAQ) unit is used, the maximum and minimum air flow rates are adjusted with the stroke limiters of the damper.

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.

Air quality and temperature controls

The cooling and heating capacities of the chilled beam are controlled by regulating the water flow rate according to the control signal of the room temperature controller.

Air quality control for a room space can be arranged using, e.g., a CO 2 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, with the airflow rate modulated in the first sequence and, if the temperature exceeds the set point, the water valve starting to open in the second sequence.

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 operate during heating periods to ensure proper heating performance.

Installation

The Halton Rex 600 adabtable chilled beam is especially suitable for ceiling mounting running parallel to exterior wall of the room. When selecting of the chilled beam orientation, the location of the supply air and water circuit connections are taken into account.

The chilled beam can be attached directly to the ceiling surface (H1 = 195 mm) or suspended using threaded drop rods (8 mm). Each beam is equipped with movable brackets fixed to both sides of the beam. It is recommended that the brackets be positioned one quarter of the unit length (L/4) away from the end of the beam.

Install the main pipelines of the cooling and heating water circuits above the level of the chilled beam in order to enable venting of the pipework.

The duct connection is at the same end of the chilled beam as the pipe connections. Relocation of the duct connection to either side of the chilled beam can be done easily on-site by using a screw driver.

An optional exhaust valve is installed in the front. Only left and right supply air duct connections are possible. By choosing the exhaust valve option, the active length is total length (L) - 500mm.

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 temperature of the inlet water for the heat exchanger is 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

Connect a manometer in the measurement tap and measure the static pressure in the chilled beam. The air flow rate is calculated according to the formula below.

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.


Fig.1. Halton Air Quality control (HAQ), manual

Adjustment of the air flow range in variable air flow applications

Switch-off the power supply of the actuator.

Disengage the actuator gear into manual override position by releasing the knob (1).

Define the maximum and minimum positions, in millimeters 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 (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...10VDC 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.
