AHRI Standard 550/590 (I-P) - 2011 with Addendum 3
Standard 550/590 Scope
This standard applies to factory-made vapor compression refrigeration Water-chilling and Water-heating Packages including one or more compressors. These Water-chilling and Water-heating Packages include: Water-cooled, Air-cooled, or Evaporatively-cooled Condensers; Water-cooled heat recovery condensers; Air-to-water heat pumps; and Water-to-water heat pumps with a capacity greater or equal to 135,000 Btu/h. Water-to-water heat pumps with a capacity less than 135,000 Btu/h are covered by the latest edition of ASHRAE/ANSI/AHRI/ISO Standard 13256. Note: This standard includes products that may not currently be covered under an AHRI certification program.

Section Scope

This section applies to factory-designed and prefabricated vapor compression refrigeration water chilling packages including one or more hermetic or open drive compressors (centrifugal, rotary screw, scroll, reciprocating, or other types), equipped with either water-cooled, air-cooled, evaporative-cooled condensers or supplied without a condenser. This section also covers water chilling packages with air or water-cooled heat reclaim condensers.
