Rookie needs some help with custom HVAC, OpenStudio

edit

Hi, it's my first post so big hello to everyone! I've got a tough situation. I'm pretty new in OpenStudio and I'm not entirely sure how to use it properly. I need to do some simulation though and to do that I need to prepare custom HVAC, so I came here to you guys, seeking for some help.

So I guess that most of my target is explained in the picture below. I need to create such system. In the ventilation I'm not quite sure is the air filter taken into consederation by OpenStudio or can it be freerly skipped, so I left question mark underneath it. The rest stays as it is. If something is unclear I'll try to explain it in the best way I can. Also, I'd be very, very grateful if you could recommend me some tutorials, sites or books - anything- to learn this fantastic application. Thanks in advance!
