⑥ Actuator

The VAV terminal unit is fitted with a differential pressure sensor for measuring the volume flow rate. The control components (attachments) include a differential pressure transducer that transforms the differential pressure (effective pressure) into an electric signal, a controller, and an actuator. For most applications, the setpoint value comes from a room temperature controller which is installed outside of the potentially explosive atmosphere. The controller compares the actual value with the setpoint value and alters the control signal of the damper actuator if there is a difference between the two values. The connections for the supply voltage and for the voltage signals are made in a terminal box that is suitable for use in potentially explosive atmospheres.

Quick sizing tables provide a good overview of the room sound pressure levels that can be expected. Approximate intermediate values can be interpolated. Precise intermediate values and spectral data can be calculated with our Easy Product Finder design program.

The first selection criteria for the nominal size are the actual volume flow rates qᵥ_min and qᵥ_max. 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 is required.

Volume flow rate ranges
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 duct pressure must be ensured for all operating conditions and for all control units. 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. The tables give the minimum and maximum values for a VAV terminal unit. Some control components may only have a limited volume flow rate range. This applies in particular to control components with a static differential pressure transducer. For volume flow rate ranges for all control components refer to our Easy Product Finder design program.

Any installation orientation
Zero point correction required

Pneumatic control

Installation orientation must be as shown on the sticker

Upstream conditions
The volume flow rate accuracy Δq_vapplies 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.

Space required for commissioning and maintenance
Sufficient space must be kept clear near any attachments to allow for commissioning and maintenance. It may be necessary to provide sufficiently sized inspection access openings.
