[Trace-users] Computer room free cooling

[John Eurek]

I want to model a data center that will use an energy recover unit, but I will duct it so that the OA enters the ERU and then go back outside, the air from the room will enter the ERU and then go back into the room.  This way I can reject heat outside on cold days without having to worry about getting crap into the data center.
 
How would I model this?  Would this be called an economizer, energy recovery, free cooling?
 
Also, the air will be taken from the room and returned to the room seperate from the CRAC unit.  It will just be a large grille sucking in air and another blowing it back in, so it isn't really tied to the CRAC.
