Function

Function


Halton CBH 



The supply air enters the plenum of the active chilled beam, from which it is diffused into the room through nozzles and the supply slot located on the top of the beam.
The air nozzle jets efficiently induce flow of 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.
Two different nozzle sizes are available to enable different supply airflow rates.

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.

The Halton CBH active chilled beam is designed for exposed installation next to the wall.
 

Installation

Installation


Halton CBH 



Fasten the unit to the wall using two assembly brackets, included in the delivery.
Adjust the beam horizontally and vertically to the desired position by using the two adjustment screws. The beam installation can be secured with screws through pre-drilled holes in the beam.

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

The supply air duct and pipe connection locations are specified when the product is ordered.
However, due to the symmetrical design, the supply air duct and pipe connection locations can be, when necessary, changed at the installation site:

  • remove the access plug and remount it in the other end of the beam
  • loosen the four fixing screws, then turn around and reassemble the heat exchanger, finally screwing in the fixing screws.


Adjustment

Adjustment


Halton CBH


Cooling

The recommended cooling water mass flow rate is 0.03…0.10 kg/s, resulting in a temperature rise of 1…3 °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 recommended inlet water temperature of the heat exchanger is 35…45 °C.
 

Balancing and control of water flow rates

The water flow rates of the beam are balanced by installing the balancing valves in the outlet water pipes of the cooling and heating water circuits.
Cooling and heating output of the beam are controlled by regulating water mass flow rates. The mass flow rate can be controlled with either an ON/OFF valve or proportionally with a 2- or 3-way valve.
 

Adjustment of supply airflow rate

Each beam is equipped with a measurement tap for static pressure measurement, which enables fast and accurate measurement of the supply airflow rate.
The airflow rate is calculated with the formula below.

The active chilled beam Halton CBH with its openable construction facilitates fast and easy cleaning of the supply air plenum and heat exchanger. In beams longer than 2500 mm, the front panel can be opened in two sections.

Clean the front panel using a damp cloth.
Clean the heat exchanger using a vacuum cleaner, taking care not to damage the aluminium fins of the coil.

The supply air plenum has an access plug on the back end of the beam for cleaning the plenum.
 

Specification

Specification

 

The active chilled beam shall have an integral uni-directional air supply.
The supply air plenum is to be manufactured as a single construction free from joints. The front panel shall be openable and detachable for cleaning without using any special tools.

The active chilled beam shall be 295 mm wide and 230 mm high, with an inlet duct diameter of 100 mm.
The front panel shall be made of galvanised steel plate to a thickness of 0.75 mm.
All visible parts shall be painted to white RAL 9010, 20 % gloss.

The cooling heat exchanger shall consist of a coil with aluminium fins and six 15-mm pipes connected in series.
All joints shall be fully soldered and factory pressure tested.
Connection pipes shall be manufactured from copper, with a wall thickness of 0.9-1.0 mm.

Heating shall be incorporated within the heat exchanger by two 10-mm pipes connected in series.

The pipework s maximum rated operation pressure is 1.0 MPa.
Each beam shall be protected by a removable plastic coating.
The duct connection and pipe ends shall be sealed during transit.
Each beam is to be identifiable by a serial number printed on a label attached to the beam.
