scope:

This standard applies to factory-made Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment as defined in Section 3.

Energy Source. This standard applies only to electrically operated, vapor compression refrigeration systems.

Exclusions. This standard does not apply to the following:

Rating and testing of individual assemblies, such as condensing units or coils, for separate use.

Unitary Air-conditioners and Unitary Heat Pumps as defined in ANSI/AHRI Standard 210/240, with capacities less than 65,000 Btu/h.

Water-Source Heat Pumps as defined in ISO/ANSI/AHRI/ASHRAE 13256-1.

Variable Refrigerant Flow Air Conditioners and Heat Pumps as defined in ANSI/AHRI Standard 1230.

Rating of units equipped with desuperheater/water heating devices (as defined in ANSI/AHRI Standard 470) in operation.

Commercial and Industrial Condensing Units with a capacity greater than 135,000 Btu/h as defined in ANSI/AHRI Standard 365 (I-P), Performance Rating of Commercial and Industrial Unitary Air-conditioning Condensing Units.

Other Applicable Standards. Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment may also be rated using the following standards:

Single vertical packaged air conditioners rated using ANSI/AHRI Standard 390.

Dedicated outdoor air systems rated using ANSI/AHRI Standard 920 (I-P).

Air conditioners and condensing units serving computer rooms rated using ANSI/AHRI Standard 1360.

Commercial and industrial unitary air-conditioning condensing units rated using ANSI/AHRI Standard 365 (I-P).

Purpose. The purpose of this standard is to establish for Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment: definitions; classifications; test requirements; rating requirements; minimum data requirements for Published Ratings; operating requirements; marking and nameplate data; and conformance conditions.

Intent. This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors, federal and state regulations, and efficiency standards developed by American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), International Energy Conservation Code (IECC), Canadian Standards Association (CSA), Department of Energy (DOE), and users.

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