Noise Selection Table (Sound Pressure Level LPA):

The sound pressure levels provided are practical values for system attenuation and room attenuation. If the sound pressure level is too high, a larger air volume regulator should be selected, and/or a silencer or casing should be used. For detailed acoustic data, refer to the 'Definitions' section.

Technical Information

Function Description: The damper blade serves as the control damper and air velocity sensor. The air velocity is measured via the air velocity duct in the axis and transmitted to the transmitter (static or dynamic). This is converted into an electrical signal and compared with the desired value. If there is a control deviation, the integrated servomotor adjusts the damper position. This keeps the air volume constant within small tolerances over the entire operating air velocity range.

Installation and Commissioning

Installation:

• Can be installed in any position
• TVE-D: For regulators with casing, insulate the remaining ducts up to the casing

Airflow Requirements:

The air velocity, which is decisive for the air volume, is measured and averaged at the damper blade. Therefore, the accuracy Aqv is independent of the upstream duct length. The design of duct connections, such as branches from a main duct, must comply with EN 1506 and EN 13180.

Elbow: An elbow without a straight upstream length for the VAV regulator has no significant influence on the accuracy Aqv.

Branch from Main Duct: No upstream length required. The branch from a main duct causes strong turbulence. The stated accuracy of the air volume qv is achievable without an upstream length.
