[TRNSYS-users] ventilation TRNBUILD

Michael,

I your ventilation system has a fan, you can calculate air changes per 
hour from air flow rate, air density and volume of the ventilated zone. If 
not, you may have to use an external program like CONTAM or COMIS to 
calculate the air changes, if you don't have an equation or something to 
approximate air flow into the zone.

Hope this was somewhat helpful.

Best regards,
Knut Erik Enerstvedt

Dear TRNSYS users,

I'm trying to implement a ventilation system in my TRNBUILD-file.  It's a 
system with natural intake and mechanical extraction.  I doubt how to 
implement it: TRNSYS offers only one possibility, and that's by defining a 
number of air changes per hour.  I think that is only valuable for the 
infilatration of my system.  Nevertheless, I think there must be a rather 
simple explanation for it, because ventilation is a basic thing for a 
building, and there must be an easy way to model it. 

Can any one help me?

Thanks a lot,

yours sincerely
