Automatic Command in an easy system is more info provided by zone dampers even though the VAR (variable air volume) allows Manage the complex systems.
The computer rack has four lovers during the roof but has a dispersion cover above that. The only thing I'm able to Assume to try and do now could be, get rid of the dispersion top rated and generate a funnel to address the fans and join directly to the duct, but this would mean a length of about three.5m of 125mm duct within the RM1/two wall.
