Abstract

La présente invention concerne un module de purification et de désinfection d'air et un climatiseur vertical. Le module de désinfection et de purification d'air comprend un cadre, un ensemble de stérilisation et de désinfection, un ventilateur de guidage et un mécanisme de filtrage, et la configuration globale est simple. Le cadre est intérieurement pourvu d'une région de traitement d'air dans laquelle l'ensemble de stérilisation et de désinfection, le ventilateur de guidage et le mécanisme de filtrage sont agencés, ce qui permet de réaliser un traitement de purification centralisé de l'air entrant dans le module de désinfection et de purification d'air, améliorant ainsi considérablement l'efficacité de purification. En même temps, étant donné que l'air s'écoulant dans le mécanisme de filtrage peut provoquer une certaine perte de volume d'air, la configuration du ventilateur de guidage peut modifier le débit d'écoulement d'air à l'intérieur de la région de traitement d'air, de façon à compenser la perte de volume d'air. La présente demande est utilisée dans le domaine des dispositifs de purification d'air.
