L'air est aspiré à travers des entrées de paroi latérale (20) situées au niveau de parties supérieures de parois latérales (10). Un dispositif de réglage d'admission d'air est commandé sur la base de la différence de pression statique entre l'espace interne et l'espace externe, qui est détectée par un manomètre différentiel (40), ainsi que des températures détectées au niveau de multiples sites dans l'espace interne de telle sorte que l'ouverture/fermeture des entrées de paroi latérale par des plaques de rotation (31) et le degré d'ouverture sont commandés en vue de réduire la différence de température dans un trajet d'écoulement d'air de l'amont vers l'aval dans la mue, et la différence de température dans la direction verticale dans laquelle les cages sont empilées.
