Abstract

L'invention concerne une pompe enthalpique (10) permettant de modifier le niveau d'humidité d'un courant d'air (12, 14). La pompe enthalpique (10) comprend un conteneur comportant un module de transfert (38) placé dans un premier courant d'air (12), le module de transfert (38) renfermant un déshydratant liquide. Le module de transfert (38) est perméable à la vapeur d'eau et imperméable au déshydratant liquide de manière à pouvoir retenir celui-ci à l'intérieur du conteneur tout en permettant de l'exposer au premier courant d'air. Le module de transfert (38) est également conçue pour faire entrer et sortie le déshydratant liquide du premier courant d'air, l'énergie latente et/ou sensible du premier courant d'air pouvant ainsi être modifiée.
