An air conditioning unit includes a conditioning chamber, a fan with a fan air input and a fan air output, and an evaporative unit. The fan and the evaporative unit are arranged in the conditioning chamber. The fan draws in entry air to enter the air conditioning unit, then through the evaporative unit, to condition the entry air to produce conditioned air. Within the conditioning chamber, the fan is positioned and configured such that at least 30% of an area of the fan air output are positioned above an average top surface of the evaporative unit, and that air from the at least 30% of the area of the fan air output is directed towards a wall of the conditioning chamber prior to being redirected downwards and through the evaporative unit.
