Abstract: An air conditioning system and method for conditioning air utilizes a main air conditioning body fitted minimally with an ambient air temperature and humidity sensor, a humidifier, a conditioned air fan, a downstream air temperature and humidity sensor, and a central controller for sensing and controlling each of the operative elements of the system. The humidifier includes a plurality of nozzles which spray conditioning water into the incoming airstream. Optional components include an air pre-heater, a pre-filter, a heat exchanger, and a final filter.
