Le principe de la fen^etre pariéto-dynamique consiste `a
faire circuler l’air neuf de ventilation entre des lames de verre
avant son introduction dans le volume habitable. Une partie de la
chaleur traversant les vitrages est alors récupérée par
le flux d’air. Actuellement la prise en compte de ce genre de syst`eme
dans les codes de simulation thermique des b^atiments n’est
pas satisfaisante. Cet article propose un mod`ele qui peut ^etre
implémenté relativement aisément dans de nombreux outils
de simulations existant. Ce mod`ele est basé sur une résolution
analytique du probl`eme de l’air circulant entre deux plaques
isothermes différentiellement chauffées. Il a été
implémenté dans la biblioth`eque de composants de l’outil
de simulation Modelica. Une attention particuli`ere a été
portée sur les échanges convectifs en lame d’air entre
les vitrages. Les résultats obtenus sont comparés `a ceux
d’un outil de simulation CFD commercial, le code Fluent© |
