Abstract
Abstract Air conditioning apparatus for the sensible cooling of useable air by the evaporative process at a cost of operation substantially lower than that of mechanical refrigeration of the same capabilities, and advantageously comprised of modular evaporator and blower units and multiple stages thereof with the use of substantially permanent inexpensive plastic materials conducive to the efficient absorption of heat between separate columns of air, one column subject to the evaporative cooling process with no energy change, and the other column subject to the sensible cooling process with a subtraction of energy from the useable air.
