Re: [TRNSYS-users] contaminant modeling

[David BRADLEY <d.bradley@tess-inc.com>]

Karol,
  I hope someone will correct me if I am wrong in this but I don't think that there is a significant decay rate in your case. I have used those decay rates only when there is something such as a chemical reaction. I have usually treated absorption of the contaminant as a sink (like plants absorbing the CO2)
Best,
 David

Dear All,

 

I would like to model CO2 concentration in such situation:

-          Single family house (wooden),

-          Outside concentration: 350 ppm (constant),

-          Initial inside concentration: 700 ppm,

-          No sources, no sinks,

-          Air node connection are defined (between thermal and external air nodes).

 

I defined CO2 with molar mass 44.01 kg/kmol, and I put 0.0007 kg/kg CO2 in each zone.

 

But what value of decay (contaminant definition and zone definition) should I use???

What does it depend on?  

 

Regards,

Karol
