[TRNSYS-users] MULTIPLE AIRNODES IN A ZONE

[David BRADLEY]

Juan,
   You would need to use TRNFlow or CONTAM (Type97) to calculate the 
rates at which air flows from one zone to another based on the 
temperature and pressure differences within your building. Type56 can, 
however, calculate the effect of known air flow rates between zones. 
Since implementing a TRNFlow or CONTAM airflow model is somewhat 
complicated, you might start off by assuming some interzonal air flow 
rates to see what the impact of those air flow rates is on the 
stratification and comfort within the building. If you assume a 
reasonably low air exchange rate and find that the comfort results are 
not significantly different from those when you assume a high air 
exchange rate then you can save yourself the time and energy of 
implementing the air flow model.
Kind regards,
  David
