Claim:
1. An air conditioning unit for use in a building space which is occupied by electrical equipment comprising: (a) an enclosure having a first wall, a second wall opposite the first wall, and a primary air intake in an upper region of the enclosure; (b) an air treatment component assembly comprising a filter section and a direct evaporative cooling section installed in parallel juxtaposition and mounted vertically within the enclosure so as to define a first chamber between the vertically mounted component assembly and the enclosure's first wall and a second chamber between the vertically mounted component assembly and the enclosure's second wall; such that air entering the primary air intake from outside the enclosure will flow, in sequence, vertically downward within the first chamber, meet with a resistive barrier at the vertically mounted filter section, thereby equalizing pressure over the entire surface of the vertically mounted filter section, and then pass horizontally through the vertically mounted component assembly into the second chamber, and vertically downward within the second chamber toward a discharge outlet in a lower region of the enclosure.
