A heat exchange process and apparatus for supplying cool air to a given location wherein a primary air stream is initially cooled by indirect heat exchange with a recirculating working fluid and thereafter evaporatively cooled by direct heat exchange with the working fluid flowing through a primary humidifying and cooling chamber. The working fluid is initially cooled in at least secondary, and preferably a secondary and intermediate, humidifying and cooling chamber by air streams which are separate from the primary air stream.

A method for cooling and supplying air to a space to be cooled comprising steps of; A. passing a secondary air stream in direct heat exchange relationship with a recirculating working fluid in a first humidifying and cooling chamber to evaporatively cool said secondary air stream and said working fluid and discharging said secondary air stream from said first humidifying and cooling chamber; B. discharging said working fluid from said first humidifying and cooling chamber and passing the working fluid through a primary humidifying and cooling chamber and thereafter collecting said working fluid; C. recirculating said working fluid through an indirect heat exchanger to said first humidifying and cooling chamber; D. passing a primary air stream in heat exchange relationship with said indirect heat exchanger to thereby indirectly cool said primary air stream and heat said working fluid and thereafter; E. passing said primary air stream passing through the indirect heat exchanger through said primary humidifying and cooling chamber in direct heat exchange relationship with said working fluid passing therethrough prior to the working fluid being collected to thereby evaporatively cool said primary air stream and said working fluid, and F. discharging said primary air stream from said primary humidifying and cooling chamber to the space to be cooled.
