Abstract
A two stage cooling system in which the first stage's cooling affect is transferred to the second stage through direct contact with an oil-like material. The oil-like material is cooled by direct contact with water which has been evaporatively cooled. The oil-like material is then utilized to cool the air stream prior to the second stage evaporative cooling. The use of an oil-like material in the first cooling stage of evaporative cooling allows a relatively dry air stream to be produced so as to fully capitalize upon the evaporative cooling affect of the second stage cooler.
