Functional description

The control damper blade works as an actuator and as an effective pressure sensor. Through the effective pressure channel in the shaft of the detected effective pressure reaches the transducer (static or dynamic), is converted into an electrical signal and compared with the setpoint value.

In the case of a control deviation, the integrated actuator changes the position of the control damper blade. As a result, the volume flow rate is maintained at a constant level in close tolerances over the entire differential pressure range.

 


Quick sizing tables provide a good overview of the minimum differential pressures, the volume flow rate accuracy and the room sound pressure levels that can be expected. Intermediate values may be achieved by interpolation. The sound power levels for calculating the sound pressure levels were measured in the TROX laboratory according to DIN EN ISO 5135 - see "Basic information and nomenclature". Precise results and spectral data for all control components can be calculated with our Easy Product Finder design program. The first selection criteria for the nominal size are the actual volume flow rates qvmin and qvmax.


Volume flow rate ranges and minimum differential pressure values
The minimum differential pressure of VAV terminal units is an important factor in designing the ductwork and in rating the fan including speed control. Sufficient static differential pressure (Δpstat,min) must be ensured for all operating conditions and for all controllers. The measurement points for fan speed control must be selected accordingly. The volume flow rates given for VAV terminal units depend on the nominal size and on the control component (attachment) that is installed.

Installation and commissioning 

  • Any installation orientation
  • TVE-D: For constructions with acoustic cladding, ducts on the room side should have cladding up to the acoustic cladding of the controller


Upstream conditions

The effective pressure, which is decisive for the volume flow rate, is recorded and averaged on the control damper blade. Therefore, the volume flow rate accuracy Δqv is independent of the upstream section.

Duct connections, e.g. branches off the main duct, must comply with EN 1506 and EN 13180.
