Function

FUNCTION

Halton CBX is a comfort units which operates like active beams with the exception of  4-way directional air distribution instead of two. It is a compact unit for cooling, heating and supply air for flush installation within a suspended ceiling.

The primary supply air enters the plenum of the CBX active chilled beam. From there it is diffused into the room through nozzles. Supply slots are located at the bottom of the beam on all the four sides. The supply air nozzle jets induce efficiently ambient room air. This 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. Supply air is mixed efficiently with the room air even with highr coooling and heating capacities ensuring good indoor environment. 

 


 

Normal flow

 

 

Boost flow.

Halton CBX cooling capacity is adjusted by lowering the frontplate from the normal position ( 1 ) to boost position ( 2 ) for a higher capacity, which is benefical in the case of meeting rooms.

 

 



  

Installation

INSTALLATION



 

 


Halton CBX confort unit is suitable for various applications due to its compact size. When selecting the chilled beam orientation, the location of the supply air and water circuit connections must be taken into account.

The chilled beam can be attached directly to the ceiling surface (H1 = 220 mm) or suspended using threaded drop rods (8 mm). Ceiling installation with brackets that are located at the sides of the unit.

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

The duct connection is located either at the left or right side of the chilled beam compared to the pipe connections (see locations on the dimensions page).


Change to the side of connection can be made on site by rotating the heat exchanger.


 

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- 0.06 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 °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 the supply-air flow rate

Each chilled beam is equipped with a measurement tap for static pressure measurement, which enables fast and accurate measurement of the rate of supply-air flow through the beam. The air-flow rate is calculated by means of the formula below.

Where k value is determined according table below: 

Nozzle Size k [l/s] k [m3/h]
A 600 0,64 2,30
A 1200 1,03 3,71
B 600 0,85 3,06
B 1200 1,47 5,29
C 600 1,16 4,18
C 1200 1,93 6,95
D 600 1,73 6,23
D 1200 2,95 10,62
E 600 2,87 10,33
E 1200 4,75 17,10
