Abstract

La présente invention concerne un élément d'échange de chaleur destiné à effectuer un échange de chaleur et d'humidité entre de l'air d'alimentation, c'est à dire l'air apporté à un espace cible à travers un passage d'air d'alimentation, et de l'air d'échappement, c'est-à-dire l'air évacué de l'espace cible à travers un passage d'air d'échappement, ledit élément étant doté d'une pluralité d'unités d'échange de chaleur latente présentant différents rendements d'échange d'humidité. La pluralité d'unités d'échange de chaleur latente sont agencées dans une relation de position telle que l'air d'alimentation passe en série d'une unité d'échange de chaleur latente présentant un rendement inférieur d'échange d'humidité à une unité d'échange de chaleur latente présentant un rendement plus élevé d'échange d'humidité, et que l'air d'échappement passe à travers la pluralité d'unités d'échange de chaleur latente en parallèle de manière divisée.
