About This Item

 

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.
