Functional description

The damper blade works as a control element and as a differential pressure sensor. Through the differential pressure duct in the axis, the detected differential pressure reaches the transducer (static or dynamic), and is converted into an electrical signal and compared with the setpoint. In case of a control deviation, the integrated actuator changes the position of the damper blade. Thereby, the volume flow rate is kept constant in close tolerances over the entire differential pressure range.

Nominal sizes	200 × 100, 300 × 100 200 × 200, 300 × 200, 400 × 200, 500 × 200, 600 × 200
Volume flow rate range	16 - 960 l/s or 58 - 3456 m³/h
Volume flow rate control range (controller with dynamic differential pressure measurements)	approx. 10 - 100 % of the nominal volume flow rate
Minimum differential pressure	up to 50 Pa (without secondary silencer)
Maximum differential pressure	Control component with dynamic transducer: 900 Pa, Control component with static transducer: 600 Pa
Operating temperature	10 – 50 °C

Quick sizing tables provide a good overview of the minimum differential pressures, the volume flow rate accuracy Δq_v 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 obtained by using our Easy Product Finder design programme. The nominal size is initially selected according to the given volume flow rates q_vmin and q_vmax.

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. It must be ensured that for all operating conditions and for all terminal units a sufficient differential pressure is applied to each controller (Δp_stmin). The measurement point(s) for fan speed control must be selected accordingly. The volume flow rate range for VAV terminal units depends on the nominal size and on the control component (attachment) used.

Quick sizing table for sound pressure levels
The quick sizing tables include common sound insulation and attenuation values. If the sound pressure level is above the permissible value, a larger air terminal unit and/or a silencer or acoustic cladding are required.

VAV terminal unit variant TVE-Q (standard, galvanised steel)

Bend

A bend without additional straight upstream flow length in front of the VAV control unit has no significant influence on the volume flow rate accuracy Δq_v.

Installation and commissioning

Almost any installation orientation

EN 1505 must be observed when making air duct connections, such as a junction from a main duct

Upstream conditions

The effective pressure, which is decisive for the volume flow rate, is recorded and averaged on the damper blade. Therefore, the volume flow rate accuracy Δqv independent of the upstream length, but in the case of junctions from the main line, depending on the installation variant of the control unit in the branch duct.
