Schematic illustration of the TA-Silenzio

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 pressure	5 – 65 Pa
Maximum differential pressure	1000 Pa
Operating temperature	10 – 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 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 pressure differential is applied to each controller (Δ_pstat,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.

Illustration example vertical

A bend – without a straight duct section upstream of the VAV terminal unit – has only a negligible effect on the volume flow rate accuracy_qv.

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 Δ_qᵥapplies to all upstream conditions.
