ASHRAE 139-2015 Standard 139-2015 -- Method of Testing for Rating Desiccant Dehumidifiers Utilizing Heat for the Regeneration Process (ANSI Approved)
standard by ASHRAE, 2015
More info
Full Description
ASHRAE Standard 139 provides uniform test methods for rating desiccant dehumidifiers that use heat for the regeneration process. It addresses the test methods, apparatus and instruments to be used, data to be obtained, and calculations needed to confirm valid test results.
The 2015 edition of the standard eliminates duplication of content in the published references. In addition, references and recommendations for measurement of moist-air properties have been revised to reflect the need for increased accuracy.
