[Equest-users] Modeling Ashrae - System 8 in equest - Fan in the parallel box

[Brian Fountain]

Konstantina,

You are correct to model VAV systems with parallel and series powered boxes as PIU system type.

This system type will enable several keywords at the zone level on the Airflow tab:

Included in these is ZONE-FAN-RATIO and ZONE-FAN-KW/FLOW where you can enter your VAV box fan power.

CAUTION: EXTERNAL SENDER
Dear equest users,
According G3.1.3.14 for system 8 the fan parallel box shall be modeled with 0.35 W/cfm fan power.
I was wondering where this paramater can be insered in equest.

In the following screenshot I have input the power of the supply fan.

Thank you very much.
