Abstract

L'invention concerne un humidificateur, comprenant : un récipient d'humidification (1), une électrode de chauffage (2) rentrant dans le récipient d'humidification (1), et une sortie de vapeur (3) pratiquée dans le récipient d'humidification (1). L'humidificateur comprend en outre un composant de retenue d'eau et un élément de mise à la masse, le composant de retenue d'eau étant conçu pour pouvoir contenir de l'eau électrifiée évacuée du récipient d'humidification (1), et l'élément de mise à la masse étant conçu pour pouvoir décharger sélectivement le potentiel de l'eau électrifiée présente dans le composant de retenue d'eau. L'invention concerne en outre un climatiseur de salle des machines comprenant l'humidificateur et un procédé de commande pour l'humidificateur. Selon l'humidificateur, il n'est pas nécessaire de couper l'alimentation électrique de l'électrode de chauffage lorsque l'eau est remplacée dans le récipient d'humidification, et l'humidification normale de l'humidificateur à électrode n'est pas affectée, de telle sorte que des fluctuations d'humidité de l'environnement sont évitées, une humidité constante de l'environnement est garantie, et l'expérience utilisateur est améliorée.
