Abstract: An air conditioning system for taking atmospheric air under any seasonal condition and delivering refrigerated, dry, high density air to a compressor which can then operate at full capacity delivering dry, full volume air to a reheater and air dryer which delivers dry plant air in a plant air system. The compressed air system has a water chiller for chilling water passing therethrough in a water line when the water is above a predetermined temperature and a pump for pumping the water from the chiller water line into an inlet air cooler and dryer which is coupled to the atmosphere to receive atmospheric air and remove moisture. The compressor receives the air from the inlet cooler and dryer, compresses the air, and delivers it to a reheat air dryer where additional moisture is removed and the air is reheated. The chiller water line from the inlet cooler dryer passes through the reheat air dryer to remove additional moisture and back into the water chiller to form a closed cycle recycling water system.
