③ Gears

④ Control components, e.g. an Easy controller

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 or with a Compact controller or with individual components (Universal or LABCONTROL).

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.

Nominal sizes	200 × 100 to 1000 × 1000 mm
Volume flow rate range	45 – 10100 l/s or 162 – 36360 m³ /h
Volume flow rate control range (unit with dynamic differential pressure measurement)	Approx. 20 to 100 % of the nominal volume flow rate
Minimum differential pressure	5 – 40 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. Sufficient static differential pressure (Δ_pstat,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.

Quick sizing table for sound pressure levels

The quick sizing tables are based on generally accepted attenuation levels. If the sound pressure level exceeds the required level, a larger air terminal unit and/or a silencer or acoustic cladding is required. For more information on the acoustic data, see basic information and nomenclature.

Ready-to-commission unit which consists of the mechanical parts and the electronic control components. Each unit contains an averaging effective pressure sensor for volume flow rate measurement and damper blades. Factory mounted control components complete with wiring and tubing. Position of the damper blades indicated externally at the shaft extension. The damper blade is factory set to open position, which allows a ventilation airflow even without control; this does not apply to variants with defined safe position NC (normally closed).

Special features

Integral effective pressure sensor with 3 mm measuring holes (resistant to dust and pollution)
Factory set-up or programming and aerodynamic function testing
Parameters can also later be set on the control component. Depending on the control component, an additional adjustment device may be necessary

Materials and surfaces

Casing made of galvanised sheet steel
Shafts made of galvanised steel
Damper blades and differential pressure sensor made of aluminium
Gears made of anti-static plastic (ABS), resistant to temperatures up to 50 °C
Plastic plain bearings

Connection

Flanges on both ends, suitable for duct connection

Technical data

Nominal sizes: 200 × 100 to 1000 × 1000 mm
Volume flow rate range: 42 – 10454 l/s or 149 – 37635 m³/h
Minimum differential pressure: up to 109 Pa (without secondary silencer)
Maximum differential pressure: 1000 Pa
Casing air leakage to EN 1751, class B
Closed blade air leakage to EN 1751, Class 1 (B + H ≥ 600 mm)

Specification text for attachment

Variable volume flow control with electronic Easy controller for applying a reference value and capturing an actual value to be integrated with the central BMS.

Supply voltage 24 V AC/DC
Signal voltages 0 – 10 V DC
Possible override controls with external switches using volt-free contacts: CLOSE, OPEN, q_ᵥmin and q_ᵥmax
Potentiometers with percentage scales to set the volume flow rates q_ᵥmin and q_ᵥmax without an adjustment device
The actual value signal relates to the nominal volume flow rate such that commissioning and subsequent adjustment are simplified
Volume flow rate control range: approx. 20 – 100 % of the nominal volume flow rate
Clearly visible external indicator light for signalling the functions: Set, not set, and power failure
Electrical connections with screw terminals
Double terminals for looping the supply voltage, i.e. for the simple connection of voltage transmission to the next controller

Bend, vertical

A bend – with a straight duct section of at least 4H upstream of the VAV terminal unit – has only a negligible effect on the volume flow rate accuracy.

Installation and commissioning

Any installation orientation (except units with static effective pressure transducer)
With flanges on both ends to make connections to the ducting
TVJ-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 volume flow rate accuracy Δq_ᵥ applies to a straight upstream section of the duct. Bends, junctions or a narrowing or widening of the duct cause turbulence that may affect measurement. Duct connections, e.g. branches off the main duct, must comply with EN 1505. Some installation situations require straight duct sections upstream.
