AHRI 740 2016 Edition, January 1, 2016
Performance Rating of Refrigerant Recovery Equipment and Recovery/Recycling Equipment
This standard applies to equipment for recovering and/or recycling, as per ASHRAE Standard 34, single refrigerants, azeotropes, zeotropic blends, and their normal contaminants from refrigerant systems. This standard defines the test apparatus, test gas mixtures, sampling procedures and analytical techniques that will be used to determine the performance of refrigerant Recovery Equipment and Recovery/Recycling Equipment.
Equipment shall be as defined in Sections 3.2.1 and 3.2.2.
Refrigerants used to evaluate equipment within the scope of this standard shall be pure halogenated hydrocarbons, hydrocarbons and blends containing halogenated hydrocarbons or hydrocarbons that are listed in AHRI Standard 700 and either are defined as ozone depleting substances (ODS) under 40 CFR 82.3 or have been designated as acceptable or acceptable with use restrictions by the U.S. EPA Significant New Alternatives Policy (SNAP) program.
Purpose. The purpose of this standard is to establish for refrigerant Recovery Equipment and Recovery/Recycling Equipment: definitions; test requirements, rating requirements, minimum data requirements for Published Ratings, operating requirements, marking and nameplate data; and conformance conditions. It establishes methods of testing for rating and evaluating the performance of refrigerant Recovery Equipment and Recovery/Recycling Equipment for contaminant or purity levels, capacity, speed, purge loss to minimize emission into the atmosphere of designated refrigerants and to assure that Recovery Equipment and Recovery/Recycling Equipment meets the minimum purity requirements for refrigerants in Section 7.8.
Intent. This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors and users.
Review and Amendment. This standard is subject to review and amendment as technology advances
