TECHNICAL INFORMATION
Function, Technical data, Quick sizing, Specification text, Order code, Related Products
The VAV terminal unit is fitted with an effective pressure sensor for measuring the volume flow rate. The control components (attachments) include aneffective pressure transducer that transforms the effective pressure into an electric signal, a controller, and an actuator; the control functions can beachieved with an Easy controller or with a Compact controller or with individual components (Universal or LABCONTROL). For most applications, thesetpoint value comes from a room temperature controller. The controller compares the actual value with the setpoint value and alters the control signal ofthe actuator if there is a difference between the two values.

③ Double lip seal
④ Control components, e.g. an Easy controller
Nominal sizes 100 – 400 mmVolume flow rate range 34 – 7591 m³/h or 10 – 2108 l/s
Volume flow rate control range (unit for dynamic effective pressure measurements) Approx. 10 – 100 % of the nominal volume flow rateVolume flow rate control range (unit for static effective pressure measurements) approx. 15 to 100 % of the nominal volume flow rate
Minimum differential pressure Up to 117 Pa (without circular silencer)
Maximum differential pressure 1000 PaOperating temperature 10 to 50 °C
Quick sizing tables provide a good overview of the minimum differential pressures, the volume flow rate accuracy and the room soundpressure 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 informationand 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 thenominal size are the actual volume flow rates q and q .
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 beensured that for all operating conditions and for all terminal units a sufficient pressure differential is applied to each controller (Δ ). The measurement pointsfor 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 airterminal unit and/or a silencer or acoustic cladding is required. For more information on the acoustic data, see basic information and nomenclature.

Installation and commissioning
Any installation orientation (except units with static effective pressure transducer)TVR-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 Δ applies to a straight upstream section of the duct. Bends, junctions or a narrowing or widening of the duct causeturbulence that may affect measurement. Duct connections, e.g. branches off the main duct, must comply with EN 1505. Some installation situations requirestraight duct sections upstream.
