ENERGY STAR Program Requirements for Automatic Commercial Ice Makers - Final Draft Test Method - Rev. Mar-2012

Sep 15, 2026

Uploaded by Jacob

This final draft test method specifies how to determine ENERGY STAR product compliance for Automatic Commercial Ice Makers (ACIM). It defines which product classes are included or excluded, establishes key definitions such as variable purge setting, and sets test conduct guidance for units connected to remote rack compressors. It also details setup and initialization expectations, test conditions aligned with 10 CFR Part 431 Subpart H, and references governing standards for energy consumption rate and potable water use.

Final Draft Test Method
Rev. Mar-2012 | | --- | --- | | 1 1 OVERVIEW
2 The following test method shall be used for determining product compliance with requirements in the
3 ENERGY STAR Eligibility Criteria for Automatic Commercial Ice Makers (ACIM) .
4 2 APPLICABILITY
5 ENERGY STAR test requirements are dependent upon the feature set of the product under evaluation.
6 The following guidelines shall be used to determine the applicability of each section of this document:
7 2.1 Included Products
8 A) All sections of this test method apply to all products covered in the scope defined in ENERGY STAR
9 Eligibility Criteria for Automatic Commercial Ice Makers: 10
11 1) Air-cooled batch and continuous type, Ice Making Head (IMH), Remote Condensing Units (RCU)
12 with dedicated condensing units, and Self-contained Units (SCU) .
13
14 2) Air-cooled RCU units designed for connection to remote rack compressors that are alternately
15 sold (with the same model number) with a dedicated remote condensing unit. 16
17 2.2 Excluded Products
18 A) The following products are not included in the scope defined in ENERGY STAR Eligibility Criteria for 19 Automatic Commercial Ice Makers:
20
21 1) Air-cooled RCU units that are designed only for connection to remote rack compressors.
22 3 DEFINITIONS
23 Unless otherwise specified, all terms used in this document are consistent with the definitions in the
24 ENERGY STAR Eligibility Criteria for Automatic Commercial Ice Makers.
25 • Variable Purge Setting: A setting that allows for the increase or decrease of purge water used
26 during ice making to accommodate for different water hardness levels.

29
Note: Stakeholders commented that the variable purge setting definition and requirements were unnecessary; however, since variable purge settings affect potable water consumption, DOE believes purge settings must be specified in the test method..

Stakeholders commented that testing RCUs designed for connection to only remote rack compressors would be difficult and should not be included in the ENERGY STAR Program. As such, DOE has proposed to remove those RCUs designed for connection to only remote rack compressors. DOE has retained those RCUs designed for connection to remote rack compressors that are also sold (with the same model number) with a dedicated remote condensing unit. DOE is interested in stakeholder feedback regarding its proposal to test these units with the least efficient dedicated RCU with which it is normally sold. 46 B) Purge Setting: 47 All variable purge settings shall be set in accordance with AHRI Standard 810-2007, Performance Rating 48 of Automatic Commercial Ice-Makers. 49 50 51 52 53 54 55 Note: Stakeholder comments noted that the purge setting requirements proposed in Draft 1 would add testing and require additional clarification for each unit tested and recommended testing units as-shipped. Draft 1 referenced AHRI 810-2007 with Addendum 1, which requires that variable purge settings shall be tested as-shipped. As such, no extra requirements have been

FAQs

Which products are included in the scope of this ENERGY STAR ACIM test method?

Included products cover air-cooled batch and continuous units, ice making heads, remote condensing units (RCUs) with dedicated condensing units, and self-contained units, plus certain alternately sold air-cooled RCU arrangements connected with a dedicated remote condensing unit.

Which products are excluded from the ENERGY STAR ACIM test method scope?

RCUs designed only for connection to remote rack compressors are excluded from the scope defined in the ENERGY STAR Eligibility Criteria for Automatic Commercial Ice Makers.

How should variable purge settings be handled during testing?

All variable purge settings must be set in accordance with AHRI Standard 810-2007 (Performance Rating of Automatic Commercial Ice-Makers), reflecting the requirement to accommodate different water hardness levels and related potable water consumption impacts.
