ApHVAC Air EXTRACT Variable
Posted: Mon Oct 01, 2012 8:35 am
We've always had an ApHVAC Air Supply variable within Vista, but it would be extremely useful if we could also have an ApHVAC Air Extract variable.
I tend to only use ApHVAC to model ventilation systems when the supply and extract are unbalanced, or I'm modelling an 'extract only' system. In both of these scenarios it can be unnecessarily difficult to analyse the results without being able to look directly at the amount of air ApHVAC is removing from a room in addition to the amount it is supplying.
You can work it out indirectly by analysing the HVAC nodes in Vista, but I don't think it's possible to look at this on a room-by-room basis and instead only for the multiplex as a combined total.
Thanks!
