[TRNSYS-users] Tr : problem of fichier air in the Calling Contam Exemple

[David Bradley]

Yujun,
 This is an interesting thing and I am not sure of the answer. I've 
never had such a problem but I must admit that I have never looked 
closely at the codes in the *.air file to make sure that they correspond 
to the output list. One thing you might do is to plot all of the output 
values and look at their magnitudes. Flows from one zone to another have 
the units of kg/h (it says kg/s in the CONTAM help file but this is not 
correct.) while flows to/from ambient have the units of airchanges per 
hour. I'll look at the code on my end and see if I can determine which 
is correct.
Kind regards,
 David
