[TRNSYS-users] Variable for air extraction from one zone

[David Bradley]

Antonio,
   I think an ideal method is to add a VENTILATION type to your zone. 
Type56 (in absence of an air flow model such as COMIS, CONTAM, or TRNFLOW) 
doesn't really care how much air you extract from the zone; it assumes that 
the pressure in the zone does not change so essentially it assumes that 
equal amounts of air are added and extracted. I would add the zone RH as a 
Type56 output and then make the VENTILATION stream temperature, RH, and air 
change rate into INPUTS, then connect the appropriate outputs of your 
circulation system to the Type56 inputs.
Kind regards,
  David
