The information given here is just to give you an idea. 

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.
