Useful additions■ Hot water heat exchanger■ Electrical heaterFor more details contact TROX Malaysia
Special characteristics■ Factory set-up or programming and aerodynamic function testing■ Volume flow rate can later be measured and adjusted on site; additional adjustment device may be necessary
Parts and characteristics■ Ready-to-commission unit which consists of mechanical parts and control components■ Averaging differential pressure sensor for volume flow rate measurement■ Damper blade■ Integral attenuator■ Factory assembled control components complete with wiring and tubing■ Aerodynamic functional testing on a special test rig prior to shipping of each unit■ Set-up data is given on a label or volume flow rate scale affixed to the unit
Construction features■ Rectangular casing■ Spigot on the inlet suitable for circular ducts to DW144, 1998■ Connection on the room end suitable for air duct profiles■ Position of the damper blade indicated externally at shaft extension■ Thermal and acoustic insulation (lining)
Materials and surfaces■ Casing and damper blade made of galvanized sheet steel■ Damper blade seal made of Chloroprene rubber■ Lining is fiber glass ■ Differential pressure sensor made of aluminum■ Plastic bearings
Mineral wool■ Internal fiber glass insulation lining. ■ Faced with woven glass fabric as protection against fiber erosion for airflow velocities up to 20 m/s■ Resistant to fungal and bacterial growth
Installation and commissioning■ Any installation orientation (except units with static differential pressure transducer)■ Return edges of the casing with drilled holes suitable for M8 threaded rods
Standards and guidelines■ Closed blade air leakage to EN 1751, Class 2 (4 – 10), Class 3 (12, 14, 16)
Maintenance■ Maintenance-free as construction and materials are not subject to wear

VAV terminal unitsFunction TVB
Functional descriptionThe VAV terminal unit is fitted with adifferential pressure sensor for measuringthe volume flow rate. The control components(attachments) include a differential pressuretransducer that transforms the differentialpressure (effective pressure) into anelectric signal, a controller, and an actuator;the control functions can be achieved withan Easy controller, with a Compact controller,or with individual components.
For most applications, the setpoint valuecomes from a room temperature controller.The controller compares the actual valuewith the setpoint value and alters thecontrol signal of the actuator if there is adifference between the two values. Anintegral attenuator reduces the noise that is created by the restriction of the airflow. The airflow velocity at the room end is,due to the larger rectangular cross section,about half the velocity in the circular duct

Volume flow rate ranges
Quick selection tables providea good overview of the roomsound pressure levels that canbe expected. Approximateintermediate values can beinterpolated. For preciseintermediate values pleasecontact TROX Malaysia.
The first selection criteria forthe nominal size are the actualvolume flow rates Vmin and Vmaxin ft3/min (CFM) and in l/s (LPS).The quick sizing tables arebased on normally acceptedattenuation levels. If the sound pressure level exceeds therequired level, a largerVAV terminal unit and/or asilencer is required.

The minimum differentialpressure of VAV terminalunits is an important factorin designing the ductworkand in rating the fanincluding speed control.
Sufficient duct pressuremust be ensured for alloperating conditions and forall control units.
The measurement points forfan speed control must beselected accordingly.

NoteThe volume flow rates given for VAV terminal units depend on the nominal size and on thecontrol component (attachment) that is installed. The table gives the minimum and maximumvalues for a VAV terminal unit.Some control components may only have a limited volume flow rate range. For volume flowrate ranges for all control components refer to TROX Malaysia

VAV terminal unit,variant TVB-C
–VAV terminal unit with acoustic cladding for the control of variable supply air volume flows–For rooms where the case-radiated noise of the unit is not sufficiently reduced by a false ceiling–The circular ducts for the room under consideration must have adequate acoustic insulation(provided by others) on the fan end.
–Acoustic cladding cannot be retrofitted–Outlet spigot with adjustable perforated damper

Upstream conditions The volume flow rate accuracy applies toa straight up streamsection of the duct.Bends, junctions or anarrowing or wideningof the duct causeturbulence that mayaffect measurement.Duct connections,e.g. branches off themain duct, must complywith EN1505.Some installationsituations requirestraight duct sectionsupstream.

A radius bend with at least 1D radius at a centre linecurvature-without an additional straight ductsection up stream of the VAV terminal unit - hasonly a neggible effect on the volume flow rateaccuracy
A junction causes strong turbulence. The started volumeflow rate accuracy can only be achieved with a straightduct section of at least 2D length upstream.Shorter upstream sections require a perforated plate in thebranch and before the VAV terminal unit. If there isno straight upstream section at all, the control will not bestable, even with a perforated plate

This specificationdescribes the generalproperties of the product
VAV terminal units for variableand constant air volume systems,suitable for supply or extract air,available in 9 nominal sizes.Ready-to-commission unit which consistsof the mechanical parts and the electroniccontrol components. Each unit contains anaveraging differential pressure sensor forvolume flow rate measurement and adamper blade.
Factory assembled control componentscomplete with wiring and tubing.Spigot suitable for circular ducts to DW 144, 1998Position of the damper blade indicatedexternally at shaft extension.Closed blade air leakage to EN 1751, Class 2 (4 - 10), Class 3 (12, 14, 16)
Special characteristics– Factory set-up or programming and function testing– Volume flow rate can later be measured and adjusted on site; additional adjustment device may be necessary
Materials and surfaces– Casing and damper blade made of galvanized sheet steel– Damper blade seal made of Chloroprene rubber– Lining is mineral wool– Differential pressure sensor made of aluminum– ABS bearings
Mineral wool– Internal fiber glass insulation lining. – Faced with woven glass fabric as protection against erosion through airflow velocities of up to 20 m/s– Resistant to fungal and bacterial growth
Technical data– Nominal sizes: 4 to 16 inches– Volume flow rate range: 10 to 1775 l/s or 21 to 3761 CFM– Volume flow rate range with electric heater: 56 to 1775 l/s or 119 to 3761 CFM– Volume flow rate control range (unit with dynamic differential pressure measurement): approx. 10 to 100 % of the nominal volume flow rate– Minimum differential pressure: 20 Pa– Maximum differential pressure: 1000 Pa
AttachmentsVariable volume flow control with electronicEasy controller to connect an external control signal;actual value signal can be integrated into thecentral BMS.– Supply voltage to controller 24 V AC– Transformer step down from 230 V AC to 24 V AC– Signal voltages 0(2) – 10 V DC– Possible override controls with external switches using volt-free contacts: CLOSED, OPEN, Vmin and Vmax– Potentiometers with percentage scales to set the volume flow rates Vmin and Vmax– 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. 10 – 100 % of the nominal volume flow rate– Clearly visible external indicator light for signaling the functions: Set, not set, and power failure Electrical connections with screw terminal
