① Effective pressure sensor

② Indicator light

③ Control components, e.g. an Easy controller

④ Damper blade with seal


The VAV terminal unit is fitted with an effective pressure sensor for measuring the volume flow rate.

The control components (attachments) include an effective pressure transducer that transforms the effective pressure into an electric signal, a controller, and an actuator; the control functions can be achieved with an Easy controller, with a Compact controller, or with individual components (Universal).

For most applications, the setpoint value comes from a room temperature controller.

The controller compares the actual value with the setpoint value and alters the control signal of the actuator if there is a difference between the two values.

An integral attenuator reduces the noise that is created by the restriction of the airflow.

 


Nominal sizes 125 – 315
Volume flow rate range 30 – 840 l/s or 108 – 3024 m³ /h
Volume flow rate control range (unit with dynamic differential pressure measurement) Approx. 10 to 100 % of the nominal volume flow rate
Minimum differential pressure5 – 65 Pa
Maximum differential pressure 1000 Pa
Operating temperature10 – 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".

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. It must be ensured that for all operating conditions and for all terminal units a sufficient pressure differential is applied to each controller (Δpstat,min). 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 for sound pressure level
The quick sizing tables are based on generally accepted attenuation and insulation levels. If the sound pressure level exceeds the required level, a larger air terminal unit and/or a silencer or acoustic cladding is required.

    Installation and commissioning

    • Any installation orientation (except units with static effective pressure transducer)
    • Return edges of the casing with drilled holes suitable for M10 threaded rods
    • TA-Silenzio-D: For constructions with acoustic cladding, ducts on the room end should have cladding up to the acoustic cladding of the controller


    Upstream conditions

    The volume flow rate accuracy Δqᵥ applies to all upstream conditions.
