ABSTRACT:
Air conditioning apparatus and a method of operation thereof, said apparatus being mounted such that the indoor section receives air to be conditioned through an opening in the bottom wall of the unit and likewise discharges the conditioned air into the enclosure to be treated through an opening in the bottom wall of the unit. The heat exchanger, fan and supplementary heaters, if used, are arranged to maximize air flow per given fan power input such that the overall efficiency of the unit can be increased by decreasing the necessary energy to circulate air through the unit. An internal wall is used to support the fan as well as define air flow paths.
