1. An air conditioning unit, comprising:
a conditioning chamber;
a fan, with a fan air input and a fan air output; and
an evaporative unit, the evaporative unit comprising two separated sets of coils, the two separated sets of coils opposing each other with the fan in between, when viewed from a top of the air conditioning unit, spaces being provided between two sides of the two separated sets of coils, the spaces being below a level of a bottom surface of the fan, and the spaces being configured to lower resistance to air flow between the evaporative unit and the fan air output;
wherein, the fan and the evaporative unit are arranged in the conditioning chamber;
wherein, 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;
wherein, 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; and
wherein the fan is a centrifugal fan, and a top of the centrifugal fan touches a top inner surface of the conditioning chamber.
