I would like to use OpenStudio to create a building energy model. Actually, there are a lots of Fan Power Ventilators (only includes fan and outdoor air mixer) inside of the buildings. However, I can't directly select Unit Ventilators from Library because of the bug of the fan (

The area that has the ventilator is also serviced by another big central AHU. That means this area already has an air loop. That's why I can't create another air loop to show this ventilator.

And then, I would like to add a component downloaded from BCL called Generic Axial Powered Roof Ventilator. However, it seems like the component can't be used directly in OSM file.

Does anyone have any ideas about this problem? That'll be very helpful! Thank you!

Answering outside of the box a little bit (because your description makes me think you don't): Are you sure you actually need a ZoneHVAC:UnitVentilator?

Unit ventilators are zone equipment units which are assembled from other components. They contain a built-in outdoor air mixer, a fan, a heating coil, and a cooling coil

is that really what you need? Do you need a heating coil, a cooling coil and an outdoor air mixer?

@Julien Marrec, what I only need is the fan and the outdoor air mixer.

@Julien Marrec, ZoneVentilation:DesignFlowRate will be a perfect choice for my model. Thank you for your help!
