Abstract: Disclosed is an air conditioner hanging unit (100), comprising: a housing including a mounting wall (110), the housing being mounted and fixed by means of the mounting wall (110) and further comprising a lower end wall (120) arranged transversely and connected to the edge of the lower end of the mounting wall (110), and an air outlet (190) being formed on the lower end wall (120); and an air supply component (180) disposed in the housing and comprising a centrifugal fan (182) pumping out air and an air supply passage (181) for delivering air; the air supply passage (181) being communicated with the air outlet (190); the centrifugal fan (182) pumping heat exchange air in the housing to the air supply passage (181) and the heat exchange air being sprayed out of the housing via the air outlet (190) in a direction parallel to the mounting wall. Such an air outlet mode prevents cool air sprayed from the air conditioner hanging unit from blowing to a user directly and prevents the user from catching a chill.
