Table for pressure loss calculation

This table shows the calculation data for all flow paths of the selected system. It provides an overview over all ending components of the network. If you select a flow path, the table Section parts displays all corresponding section parts. The most unfavorable flow path is highlighted in a different color. You can also select the most unfavorable flow path by pressing U.

Column

Description

No.

Number of the flow path.

Type

SU: Supply air

EX: Extract air

OA: Outdoor air

EXH: Exhaust air

Outlet

Name of the outlet or partial network end.

Volume flow rate

Volume flow rate in this particular flow path.

The volume flow rate of this flow path can be entered in this table. To avoid recalculating the network every time a change is made, deactivate the Recalculate after editing of section parts or components option in the Settings.

dp-pipes

Pressure loss of the straight air ducts.

dp-single resistance

Pressure loss of the single resistances.

dp-balancing

Sum of the balancing pressure losses of the flow path.

dp Total

Total pressure loss of a flow path.

Table for sound level calculation

This table shows the calculation data for all flow paths of the selected system. It provides an overview over all ending components of the network. If you select a flow path, the table Section parts displays all corresponding section parts. The most unfavorable flow path is highlighted in a different color. You can also select the most unfavorable flow path by pressing U.

Column

Description

No.

Number of the flow path.

Type

SU: Supply air

EX: Extract air

OA: Outdoor air

EXH: Exhaust air

Outlet

Name of the outlet or partial network end.

Volume flow rate

Volume flow rate in this particular flow path.

The volume flow rate of this flow path can be entered in this table. To avoid recalculating the network every time a change is made, deactivate the Recalculate after editing of section parts or components option in the Settings. In the Calculation presettings of the Settings, you can define the unit used for the volume flow.

Lw outlet

Unweighted sound power level at the outlet of the diffuser.

-dLp Room/Ambience

Sum level of room/ambient attenuation for this outlet.

Result

Unevaluated sound pressure level at the measuring point (ear).

Lp Measuring point

The A-evaluated sound pressure level at reading point.

Lp Room/Ambience target

Required A-weighted sound pressure level in the room or in the environment.

Lp Room/Ambience actual

Resulting A-weighted total sound pressure level of all outlets in the room or in the environment.
