AHRI 1600 (I-P): Performance Rating of Unitary Air-conditioning and Air-source Heat Pump Equipment

The purpose of AHRI 1600 is to establish the following for unitary air-conditioners and unitary air-source heat pumps: definitions, classifications, test requirements, rating requirements, operating requirements, minimum data requirements for published ratings, marking and nameplate data, and conformance conditions.

This standard applies to factory-made unitary air-conditioners and unitary air-source heat pumps with capacities less than 65,000 Btu/h as defined in Section 3.

Energy Source

AHRI 1600 applies only to electrically operated, vapor compression refrigeration systems.

Exclusions

This standard does not apply to the rating and testing of:

• Heat operated air-conditioning/heat pump equipment.
• Packaged Terminal Air conditioners/Heat Pumps, as defined in AHRI 310/380 (CSA-C744).
• Room air-conditioners/heat pumps.
• Unitary air-conditioners and unitary air-source heat pumps as defined in AHRI 1340 with capacities of 65,000 Btu/h or greater.
• Water-source heat pumps, ground water-source heat pumps, or ground-source closed-loop heat pumps as defined in ANSI/AHRI/ASHRAE/ISO Standard 13256-1-1998 (R2012) and ANSI/AHRI/ASHRAE/ISO Standard 13256-2-1998 (R2012).
