[TRNSYS-users] TRNSYS-users Digest, Vol 68, Issue 15

[王洋]

Dear all,

   About TRNFLOW: I design a simple air flow Zone, it only has 5 Air Links,
one of them is Flow Controller which controls air flow through Window
between outside and the Zone. Please tell me: How to design Pollutant Model?
It only has CO2 as Pollutant. Especially. about design of the mass balance.
CO2 stored, CO2 input, CO2 output. If you know, Please tell me step by step
in detail! Many thanks!

  Br.
