Abstract

L'invention concerne un générateur d'eau atmosphérique et un procédé de fonctionnement d'un générateur d'eau atmosphérique. Un compresseur (30) fait circuler du réfrigérant à travers un condenseur (27) et un évaporateur (19). Une batterie (25) stocke l'énergie nécessaire pour entraîner le compresseur (30). L'évaporateur (19) refroidit l'air qui circule à travers le générateur d'eau atmosphérique. Après la collecte de l'eau, l'air s'écoule vers une chambre (24) qui accueille la batterie (25). Après l'étape d'évaporateur (19), le flux d'air est plus froid que celui de l'air ambiant. L'air froid refroidit la batterie (25), ce qui réduit la charge thermique de la batterie (25). L'air refroidi peut être amené à circuler à travers le système jusqu'à divers composants, car le flux d'air a deux objectifs. Après la réalisation du premier objectif, qui est la condensation de l'eau provenant de l'air ambiant, le flux d'air peut être utilisé pour le deuxième objectif, qui est le refroidissement d'au moins un composant du générateur d'eau atmosphérique.
