Re: [TRNSYS-users] TYPE 97 and CONTAM



Giacomo,
It may be an issue of air density. I think that CONTAM reports volumetric flows while TRNSYS uses mass flows. I am not sure that there is any way of finding out what the density of the air flows in CONTAM is.
Cheers,
 David

Hi,
I am having some problems with TYPE 97. I am modeling a single zone building
and i have told TYPE 97 to print the airflow from that zone to the ambient
and from the ambient to that zone (the two values should be the same of
course) as
I want to be sure that everything is working properly.
Air is supposed to flow in from one device at the bottom of the zone and
it is leaving from three exits in the top.
In CONTAM everything seems to work fine but in TRNSYS i am told that the
two values (inflow and outflow) are different.
Any help will be appreciated,
thanks in advance
giacomo
