Cooling by evaporation is satisfactory only when the air to, be cooled is very dry; air motion as a means of producing cooling effect is never entirely adequate in the range of high, temperatures. Of the two, evaporative cooling, or adiabatic saturation of the air, is a much more, dependable method which will make more reduction in the effective temperature than will an increasing, air motion within permissible limits. As an example of this, consider, an outdoor condition of 96 F dry-bulb; and 80 F wet-bulb. The effective temperature is. 85.7 F and,, if the,-still; air is moved,with a velocity of 300fprii,,the effective ,temperature-will be. reduced only 2.0 F while saturation at the .wet-.bulb temperature would reduce the effective temperaJure 5.7 F. At300.fpm velocity this satu rated air would reduce the effective temperature to, 75.6 F, thus making a total improvement of 10.1 F. ... . \* .
