  • the vertical air conditioner indoor unit can change the angle between the purified air flow or fresh air flow and the heat exchange air flow by adjusting the air outlet direction of the first air outlet 12 and/or the second air outlet 22, thereby changing the intersection position of the two. Specifically, the larger the angle between the direction of the purified air flow or the fresh air flow and the direction of the heat exchange air flow, the closer the intersection position is, that is, closer to the vertical air conditioner indoor unit; the smaller the angle is, the farther the intersection position is, that is, the farther away it is.
  • Vertical air conditioner indoor unit The vertical air conditioner indoor unit can adjust the aforementioned intersection position according to the position of the human body to avoid the intersection position being close to the human body and causing discomfort to the human body.
  • the vertical air conditioner indoor unit may further include an upper connection shell 40 , and the top ends of the first air supply column 10 and the second air supply column 20 are both connected to the upper connection shell 40 .
  • the first air supply column 10 and the upper connection shell 40 can be made into an integral part, and the second air supply column 20 and the upper connection shell 40 can also be made into an integral part.

Abstract

Unité de climatisation intérieure verticale comprenant une colonne inférieure, une boîte de purification, une canalisation d'air frais et un module de lavage. La colonne inférieure est située au fond de l'unité de climatisation intérieure verticale et est dotée d'une entrée d'air intérieure. La boîte de purification est située dans la colonne inférieure et est dotée en interne d'au moins un module de purification. La canalisation d'air frais est utilisée pour introduire un flux d'air frais extérieur et présente une sortie en communication avec l'intérieur de la boîte de purification. Le module de lavage est disposé à l'intérieur de la colonne inférieure et présente une entrée en communication avec la boîte de purification. L'unité de climatisation intérieure verticale est configurée pour présenter un mode de purification dans lequel de l'air intérieur entre dans la boîte de purification à travers l'entrée d'air intérieure, s'écoule à travers le module de purification pour former un flux d'air purifié, puis entre dans le module de lavage, et un mode d'air frais dans lequel un flux d'air frais entre dans la boîte de purification et entre ensuite dans le module de lavage.
