[TRNSYS-users] Stratification and Radiation in TRNSYS

[Łukasz Wątły]

Dear All,

I am writing to you with some questions that appeared while working on the
model in TRNSYS. I am preparing a model of 3-storey building with
low-temperature floor and ceiling heating installed.

I am interested in doing the vertical stratification on each and every
floor of this building, meaning that I would like to have at least 4
different nodes on the given floor. Is it possible to do the stratification
in this way with TRNSYS? If so, how could I approach it?

Next problem regards the aspect of radiation. As each air node represents
each zone, the air normally does not receive any radiation heat, but the
solid does. However, in the tutorial it is mentioned that air node receives
heat radiation. My question is how does it happen in more details?

Lastly, if I have the solid between two air nodes, how can this solid get
the heat from source of heat directly by radiation? How does it influence
the air nodes?

I would be grateful if somebody could share his/her knowledge. Thank you in
advance for your help.

I look forward to hearing from you.

Kind regards,
Lukasz Watly
