TVE VAV terminal unit

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 kept constant in close tolerances over the entire differential pressure range.

 


Nominal sizes100 – 250 mm
Volume flow rate range

4 – 637 l/s or 14 – 2293 m³/h

Volume flow rate control range (unit with dynamic effective pressure measurement)

approx. 4 to 100 % of the nominal volume flow rate
Minimum differential pressure

Up to 82 Pa (without circular silencer)


Maximum differential pressureControl component with dynamic transducer: 900 Pa, Control component with static transducer: 600 Pa
Operating temperature10 to 50 °C

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". Exact results as well as spectral data for all control components are provided by the design 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. It must be ensured that under all operating conditions a sufficient pressure differential across the regulator (Δpstat,min) is pending. 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.

Quick sizing table sound pressure level

In the quick sizing are generally accepted attenuation and insulation values have been taken into account. If the sound pressure level exceeds the required level, a larger air terminal unit and/or a silencer is required. Further information on the acoustic data can be found in the basic information and nomenclature.

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.
