Standard 133-2008 provides procedures for testing direct evaporative cooling devices under laboratory conditions to obtain rating information. As an ASHRAE method-of-test standard, it is intended to offer recommended practices and accurate measurement procedures. This revision makes one key change to the standard: the density correction to saturation effectiveness has been simplified by clarifying that it shall be reported only as a function of actual test standard airflow.
