Questions in WUFI Plus Air Flow Model

Post by hs » Mon Oct 01, 2018 7:56 pm -1100

We are using Air Flow Model in WUFI Plus V3.1.1.0.
It would be highly appreciated if you could tell us how to implement the following conditions in WUFI Plus with certain switches or functions.

1) Specify the arbitral time series of DB & RH for a supply air not equal to the outdoor air.

2) Output the time series of the specific interzonal air flow rate, for example, interzonal air flow rate of zone A and B, while the zone C exist and connected to zone A as well.
In the application, the interzonal air flow on a zone seems to be sum up for all connected zones.

Thank you in advance for your cooperation.

Hello HS,

1) At the moment, it's only possible to define, or set supply air condtions with an workaraound. you can add an fictive addtional zone (maybe as an attached zone) with an predefined inner climate and then define the supply air flow from this zone to your building.

2) Only the sum of interzonal air flow is shown and saved as result, if you need to investigate the flow rates in detail you need to check "Retain calculation results" for interzonal components (between Zone A and B, or C), used as flow paths. Then you get the simulated airflow via those components.
