Function

Function


Halton Jaz JDE


 

The Halton Jaz JDE is an active ceiling diffuser for exhaust air.

The air is exhausted from the space through the perforated front panel and the side slot of the diffuser. Maximum airflow rate is selectable and will be made with the movable balancing vanes in the diffuser. 

An external room controller varies the room airflow rate by running the Halton Jaz JDE diffuser's actuator with a standard 2 - 10 V control signal.
The pressure dependent function of the Halton Jaz JDE operates in combination with constant pressure ductwork.


Effective sound attenuation reduces the generated noise and attenuates the duct noise.

Wiring

The Halton Jaz for Vario, JDE active air exhaust diffuser shall be connected to the control system.

With 10 V control signal the active flow control damper is fully open.
 

Balancing

The balancing function will not be avaialble when Halton Jaz JDE exhaust diffuser is connected to Halton Vario control system and when getting the control signal from supply air terminal. In that case the control vanes should be adjusted to the position 20 and maximum and minimum airflow rates shall be adjusted with the control signal.

In balancing function ensure that the flow control damper on each active Halton Jaz JDE exhaust air diffuser is fully open. This can be done either mechanically or electrically:

  • If the power is connected to the active diffuser, press the knop in the actuator and turn the damper blade on horizontal position (visual mark on the end of blade axle showing the position).
  • If power is not connected to the diffuser, please make sure that the control signal is constantly at 10 VDC.

Check that the duct zone constant pressure is at the intended level (for examble between 30 to 50 Pa. If the airflow rate of the active exhaust diffuser is too high, adjust the position of the balancing vanes to the closer position. If the maximum airflow can not be reached, open the vanes first fully open and if this is not enough, increase the duct zone pressure.

The minimum airflow rate if factory pre-adjusted to the variable flow control damper and can not be adjusted.

Airflow rate is calculated using the pressure difference reading and the k factors (see formula below).

Code description
 1.    Diffuser plenum
 2 .   Front panel
 3.    Fixing screws
 4.    Balancing vanes

For servicing open the front panel (2) of the diffuser and detach the flow control element. Detach the balancing vanes (4) by opening the screws (3) and remove the vanes.

Clean the parts with a damp cloth instead of immersing in water.

Replace the parts in opposite order. Ensure that the balancing vanes are in right position.

Specification

Specification

 

The active exhaust diffuser shall be made of steel and powder painted with a white (RAL 9010) standard colour. Air shall be exhausted through the perforated front panel and the side slot of the diffuser.

The system balancing and maximum airflow selection shall be made with the balancing vanes in diffuser.
Variable airflow rate shall be controlled with the electrical flow control damper.

The diffuser shall be integrated to a balancing plenum designed for the active diffuser installation and equippped with air measurement  and sound attenuation properties.
