Abstract

L'invention concerne un climatiseur, comprenant : un boîtier (101) sur lequel une sortie d'air supérieure (11) et une sortie d'air inférieure (12) sont présentes, la quantité d'air fournie par la sortie d'air supérieure (11) étant supérieure à celle fournie par la sortie d'air inférieure (12). La quantité d'air fournie par la sortie d'air supérieure (11) est supérieure à celle fournie par la sortie d'air inférieure (12), de telle sorte que, lors du chauffage, le climatiseur puisse réaliser un effet dans lequel un écoulement d'air fourni depuis la sortie d'air supérieure (11) supprime un écoulement d'air fourni à un emplacement de la sortie d'air inférieure (12), ce qui augmente ainsi efficacement la zone d'air chaud atteignant le sol, et augmente le niveau de confort fourni par le climatiseur.
