Re: [TRNSYS-users] mass flow rate between adjacent zones



Pu,

 Type56 (for which TRNBuild is the interface) is a thermal model of the building. Usually the way interzonal air flow is computed is to couple the Type56 thermal model with either COMIS (through TRNFlow) or CONTAM (through Type97 or Type98). Both COMIS and CONTAM are "bulk air flow models." Type56 passes the zone temperatures to the bulk air flow model, which computes zonal pressures, air density, etc. and the resulting interzonal air flow rates and then passes those back to Type56.

kind regards,

 David

Hello,
        I'm doing a zonal model. Zonal simulation involves the calculation of mass flow rates between adjacent zones. in my study, the mass flow rates ṁi,j between adjacent zones i and j are calculated with Matlab which was coupled with TRNSYS . However, the calculation of mass flow rates between adjacent zones involves the air density, mass and pressure in each zone.  But TRNBuild seems to be unable to output density, mass and pressure. I don't know if I didn't find it. How can I get these data?

kind regards,
Pu
