Bilan explicite du rayonnement

Post by Mathieu.nicolay »

Bonjour,

Voilà je me demande dans quel cas devons nous cocher la cas du bilan explicite du rayonnement ?

D'avance je vous remercie pour votre réponse.

Dear Mathieu,

the explicite radiation balance is recommended for all roof simulations as well as if you are interested in the surface temperature courses of highly insulated walls (e.g. concerning maximum and minimum temperature, dew water hours, algae growth risk evaluation...)

best regards

Merci pour votre réponse

Mais pourquoi est il recommandé ?

Et qu'est ce que le bilan explicite ?

Cordialement

Only with explicite radiation balance the long wave radiation exchange is simulated - thus overcooling effects during night time cannot be considered without.

You can switch it on under "Coefficients de transfert surfaciques": "bilan explicite de rayonnement".
