[TRNSYS-users] Fwd: coupling air flow

[David BRADLEY]

Michele,

   There are two tools available for determining the quantity of 
coupling airflow. One is Type97 (or Type98) (both of which are links 
between TRNSYS and a freely available software tool called CONTAM). The 
other is a commercially available TRNSYS add-on called TRNFlow. The idea 
behind both is that the Trnsys building thermal model (Type56) provides 
zone temperatures to the airflow model (CONTAM or TRNFlow). The airflow 
model takes those temperatures (as well as ambient conditions and a 
certain amount of building geometry with which the thermal model is not 
usually concerned) and computes the corresponding interzonal air flows. 
These are passed back to Type56, which recomputes zonal temperatures. 
Iteration continues until both the thermal and airflow models agree.

kind regards,

  David
