Abstract

La présente invention concerne un appareil de pompe à chaleur pour changer l'air dans des espaces fermés, et un procédé de fonctionnement associé. En particulier, l'invention concerne un appareil de pompe à chaleur qui permet de changer l'air dans des espaces fermés pendant chaque saison de manière efficace, sans utiliser de systèmes d'équilibre complexes du cycle thermodynamique. L'appareil comprend un dispositif qui augmente le débit de fluide de travail qui entre dans l'évaporateur, si les conditions externes le requièrent, et un dispositif pour l'inversion de flux d'air au moyen du condensateur et de l'évaporateur, sans l'inversion du cycle thermodynamique.
