Abstract: The invention relates to a multi-component air conditioning system that cools air below the pre-treatment wet bulb temperature without the use of a mechanical vapor compression system. A heat exchanger cools air followed by an evaporative cooling process that further cools the air through the vaporization of water. A heat rejection unit removes warm air from the system and cools water that can be recycled into a reservoir. A chamber separation plate can be moved to adjust the capacities of the cooling unit and the heat rejection unit. The flow of water through the system can also be controlled. This allows greater variability of capacity and temperature control.
