[TRNSYS-users] TRNFLOW and relative humidity

[Stefan de Kool]

Dear Oliver,

 

your problem looks simular to a problem I had with pollution concentrations.
Perhaps the attached discussions can help. Good luck

 

Kind regards,

Stefan de Kool

Betreff: [TRNSYS-users] TRNFLOW and relative humidity

Hello,

I am using TRNFLOW to calculate the air flow between different zones (in the
case of one volume, I defined a fictive “large opening” between the lower
and the upper part of the room).

As I want to calculate the relative humidity, I get the following message:

 

Small internal timesteps (<0.1% of simulation timestep) used for humidity
calculations due to large coupling air flows between zones!

 

How could I reduce the calculated air flow or is it another way to solve
this problem?

 

Thank you for your help,

 

Olivier.
