Full Description
The purpose of this standard is to establish for water-chilling packages using the vapor compression cycle: definitions; requirements for testing and rating; minimum data requirements for published ratings; marking and nameplate data; and conformance conditions. This standard applies to factory-designed and prefabricated vapor compression refrigeration water chillingpackages 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 standard also covers water chilling packages with air or water-cooled heat reclaim condensers.This standard is a combination of the former ARI 550-92 and 590-92.
