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 rotation of the fan.

This standard requires that packaged and component direct evaporative air coolers 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, agricultural, 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.
