scope:

The scope of this standard covers a method of testing for rating the saturation effectiveness, airflow rate, and total power of packaged and component direct evaporative air coolers

Covered tests also include the methods for measuring the static pressure differential of the direct evaporative air cooler, density of the air, and speed of rotaion of the fan

This standard requires that packaged and component direct evaporative air cooler be simultaneously tested for airflow, total power, and saturation effectiveness

The ratings resulting from application of this standard are intended for use by manufacturers, specifiers, installers, and users of evaporative air cooling apparatus for residential, commercial, agriculture, and industrial ventilation; for air cooling applications; and for commercial, industrial, and agricultural processing applications

PURPOSE

This standard establishes a uniform method of laboratory testing for rating packaged and component direct evaporative air coolers
