AHRI 1365 (SI/I-P): Performance Rating of Commercial and Industrial Unitary Air-conditioning and Heat Pump Condensing Units

Standard Scope

This standard establishes definitions, classifications, test requirements, rating requirements, minimum data requirements for published ratings, operating requirements, marking and nameplate data, and conformance conditions that include the cooling IVEC annualized metric and full load EER2 metric and heat pump IVHE and IVECC annualized efficiency metrics and full load COP2H at 47°F (8.3°C), 17°F (‑8.3°C) and 5°F (‑15°C) for commercial and industrial unitary air-conditioning and heat pump split condensing units.


AHRI 1365 applies to factory-made commercial and industrial air cooled, water cooled and evaporatively cooled unitary air-conditioning and air source heat pump condensing units greater than or equal to 135,000 Btu/h as defined in Section 3.2.


Exclusions


This standard does not apply to the following:



  • Commercial and industrial unitary air-conditioning and heat pump equipment with a capacity less than or equal to 135,000 Btu/h (39.5 kW) and greater than or equal to 65,000 Btu/h (19 kW) as defined in AHRI 340/360 (I-P) and AHRI 1340 (I-P). Note: Condensing units with a capacity ≤135,000 Btu/h (39.5 kW) are rated as a matched system with fan coil or air handler.

  • Air-cooled unitary air-conditioners and unitary heat pumps as defined in AHRI 210/240-2024 (I-P) and AHRI 1600 (I-P), with capacities less than 65,000 Btu/h (19 kW)

  • Testing and rating of condensing units for refrigeration purposes, as defined in AHRI 520

  • Testing and rating of condensing units for dedicated outdoor air systems, as defined in AHRI 920 (I-P) and AHRI 921 (SI) with Addendum 1

  • Potable water heating equipment units covered by AHRI 1300 (I-P) and AHRI 1301 (SI)

  • Water-source heat pumps as defined in AHRI 600 (I-P)

  • Variable refrigerant flow air-conditioners and heat pumps as defined in AHRI 1230 (I-P)

  • Rating of units equipped with desuperheater/water heating devices as defined in AHRI 470

  • Units with adiabatically pre-cooled condensers


Other Applicable Standards


Commercial and industrial unitary air-conditioning and heat pump outdoor condensing units can be rated using AHRI 365 (SI/I-P).
