Product Definitions

Air-Cooled Water-Chilling Package. A factory-made and prefabricated assembly (not necessarily shipped as one package) of one (1) or more compressors, condensers and evaporators, with interconnections and accessories including controls, designed for the purpose of cooling water. It is a machine specifically designed to make use of a vapor compression refrigeration cycle to transfer heat from a cold water fluid circulating system to the air.

Custom Unit. A unit that is not specifically listed in a publicly available sales brochure, magazine advertisement, website posting or Catalog / Selection Rating Application that is a single instance product which contains components or additions that change the performance such that ratings can no longer be obtained by utilizing the Participant’s Catalog / Selection Rating Application. Custom Units shall not be certified and shall not be listed in the AHRI Directory of Certified Product Performance.

Field Trial Unit. A unit that is produced and provided to a customer, for the purpose of gathering data on potential new products. These units are intended to transition into regular production should the field trial be successful. Field Trial Units are subject to the requirements of Custom Units. Field Trial Units shall not be certified and shall not be listed in the AHRI Directory of Certified Product Performance.

New Product Introduction. A new product is one that falls under the Program scope that is available to be marketed, but is not available for standard production and is not listed in the AHRI Directory of Certified Product Performance. Within nine (9) months after AHRI has received notification of New Product Introduction Unit, the Participant shall add the New Product Introduction Units to the Directory in accordance with Section 9.2 or else be in violation of AHRI’s Certify-All Policy.

Modular Chiller Array. A combination of individual certified chillers that may or may not include, from the factory, all required piping, wiring and controls to make the modular chiller array complete. The Modular Chiller Array is not certified, similar to when other certified chillers are piped and controlled together in the field.

Program Scope

 

Certified Ratings

This Program tests and certifies Air-Cooled Water-Chilling Packages Ratings as defined in this Section.

Tested Cooling Ratings. AHRI tests published ratings to AHRI Standards 550/590 (I-P) and 551/591 (SI) and EN Standards 14511 and 14825.

AHRI Standards 550/590 (I-P) and 551/591 (SI) Ratings. The following ratings are verified by test in accordance with AHRI Standards 550/590 (I-P) and 551/591 (SI):

  • Full-load cooling capacity;
  • Cooling efficiency;
  • Evaporator water pressure drop; and
  • Integrated Part-load Value (IPLV.IP or IPLV.SI) or
  • Non-Standard Part-Load Value (NPLV.IP or NPLV.SI)

Units that are not able to operate at Standard Rating Conditions shall be tested at the unit design conditions and NPLV.IP or NPLV.SI conditions.

Additionally, AHRI shall select a random point within each unit’s published AHRI Certified operating map. This random operating point (5th point) shall be selected to allow AHRI to certify the published operating map conditions at which the unit can operate.

EN Standards 14511 and 14825 Ratings. For units certified to EN Standards 14511 and 14825, The following ratings are verified by test at EN Standard Rating Conditions in in accordance with EN Standards 14511 and 14825:

  • Full-load cooling capacity;
  • Cooling efficiency;
  • Evaporator water pressure drop;
  • Seasonal Energy Efficiency Ratio (SEER); and
  • Off mode ratings listed below
    • Thermostat off
    • Standby
    • Crankcase heater (as applicable)
    • Off (as applicable)

Certified Cooling Ratings. AHRI certifies published ratings to AHRI Standards 550/590 (I-P) and 551/591 (SI) and EN Standards 14511 and 14825.

AHRI Standards 550/590 (I-P) and 551/591 (SI) Ratings. AHRI certifies the following published operating map ratings in accordance with AHRI Standards 550/590 (I-P) and 551/591 (SI):

  • Full-load cooling capacity operating map (100% of rated full-load capacity);
  • Cooling efficiency operating map (100% to 25% of rated full-load capacity);
  • Evaporator water pressure drop operating map (100% to 25% of rated full-load capacity); and
  • Integrated Part-load Value (IPLV.IP and IPLV.SI).; or
  • Non-Standard Part-load Value (NPLV.IP and NPLV.SI)

EN Standards 14511 and 14825 Ratings. For units certified to EN Standards 14511 and 14825, AHRI certifies the following published EN Standard Rating Condition ratings in accordance with EN Standards 14511 and 14825:

  • Full-load cooling capacity;
  • Cooling efficiency;
  • Evaporator water pressure drop; and
  • Seasonal Energy Efficiency Ratio (SEER).
