Positive Displacement Condensing Units

inactive
Organization: AHRI
Publication Date: 1 January 1997
Status: inactive
Page Count: 7
scope:

This standard applies to electric motor-driven, single capacity positive displacement refrigerant compressors; compressor units; and condensing units for refrigeration applications, air-cooled, evaporatively-cooled, and water-cooled.

Refrigerant. The rating points in this standard are based on commonly used refrigerants. This standard is intended to serve as a guide for use with other refigerants.

Ammonia. The standard does not apply to positive displacement compressors and compressor unit employing ammonia as the refrigerant, as covered by ARI Standard 510 for Ammonia Compressor Units.

Other Exemptions. This standard does not apply to compressors, compressor units and condensing units intended for use in:

a. Household refrigerators

b. Farm and home freezers

c. Automotive air-conditioners

d. Room air-conditioners

e. Dehumidifiers

Purpose. The purpose of this standard is to establish, for positive displacement refrigerant compressors and compressor units, and condensing units for refrigeration applications; definitions; requirements for testing and rating; and operational requirements.

This standard is intended for the guidance of the industry, including manufacturers, distributors, installers, contractors, and consumers.

Review and Amendment. This standard is subject to review and amendment as the technology advances.
