AHRI 210/240 (I-P): Performance Rating of Unitary Air-conditioning and Air-source Heat Pump Equipment

Standard Scope

AHRI 210/240-2024 (I-P) establishes definitions, classifications, test requirements, rating requirements, operating requirements, minimum data requirements for published ratings, marking and nameplate data, and conformance conditions for unitary air-conditioners and unitary air-source heat pumps.


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


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