AHRI 580 (SI/2014): Non-condensable Gas Purge Equipment for Use with Low-pressure Centrifugal Liquid Chillers (Reaffirmed May 2022)

Standard Scope

This standard applies to non-condensable gas purge equipment for low-pressure centrifugal liquid chillers, as defined in Section 3. This standard defines general equipment requirements, test methods, and analysis techniques used to determine the performance rating for purge equipment that removes non-condensable gases from low-pressure centrifugal liquid chillers. This purge equipment is typically used in conjunction with chillers which operate with at least a portion of the system below atmospheric pressure.
