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



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

To: TRNSYS-users-request@engr.wisc.edu

Hello all,
I'm trying to recirculate the one zone air, cooling  it at the same time (using Type56, Type32, Type92, Type3, Type 33, Type 2...). My main problem is that I don't know how to generate one variable for the extraccion of the air. I use the infiltration when I do the zone with prebid, but I think is not the good way.
Thanks in Advance
Antonio Aguirre
