Rulemaking for Automatic Commercial Ice Makers Energy Conservation Standard

Sign up for e-mail updates on regulations for this and other products

The purpose of this rulemaking is to: 1) establish energy conservation standards for cube ice makers with capacities between 50 and 2,500 pounds per 24-hour period; and 2) determine whether to establish energy conservation standards for additional types of automatic commercial ice makers as well as ice makers with capacities greater than 2,500 pounds per 24-hour period. The existing standards were prescribed by the Energy Policy Act of 2005 (EPACT 2005) amendments to the Energy Policy and Conservation Act (EPCA). EPACT 2005 also authorizes the Department of Energy (DOE) to issue standards for other types of automatic commercial ice makers.

The U.S. Department of Energy ("DOE" or "the Department") is currently conducting a rulemaking to update the energy conservation standard for automatic commercial ice makers (ACIM). As part of this rulemaking, DOE carried out detailed energy modeling using the FREEZE simulation program ("FREEZE" or "the model") to verify and extrapolate the results of the reverse engineering process. FREEZE is an energy model that simulates the performance of both batch and continuous ice makers. It calculates thermal loads required to cool incoming water and freeze ice, and accounts for compressor power input based on detailed compressor performance information. During the NOPR analysis, DOE made several adjustments to the model’s calculations based on comments and available information. The key outputs of the model used in the rulemaking’s engineering analysis are presented in the technical support documents. See http://www.regulations.gov/#!documentDetail;D=EERE-2010-BT-STD-0037-0061.

Recent Updates

In order to facilitate additional review of the model and gather additional feedback and data from interested parties, DOE held a public meeting on June 19th, 2014 to discuss the use of the model in the engineering analysis. During this meeting, manufacturers expressed an interest in being able to input their own data parameters into the model in order to evaluate the model's results. To accommodate this request and in an effort to be open and transparent, the Department’s contractor is available to work with manufacturers, under non-disclosure agreement if necessary, who are interested in evaluating the model’s results and comparing its performance predictions with test data when calibrated and used for their specific ice maker designs. In addition, DOE will consider further adjustments to the model's calculations to the extent that data showing impacts of energy reductions associated with component upgrades can be provided with sufficient detail. Based on these model adjustments, DOE's analysis that will support the energy conservation standards for ACIM will be revaluated and these interim results may be presented to the public through a Notice of Data Availability (NODA) should DOE determine such action is warranted.

DOE published a notice of public meeting regarding energy conservation standards for automatic commercial ice makers. 79 FR 33877 (June 13, 2014). A public meeting is scheduled for June 19, 2014.

Statutory Authority

The EPACT 2005 amendments to EPCA require DOE to conduct two cycles of rulemakings to determine whether to amend the standards for automatic commercial ice makers—both those prescribed by EPACT 2005 and those prescribed by DOE. (42 U.S.C. 6313(d)) In the first cycle, the subject of this rulemaking, DOE must publish a final rule establishing such amended standards by January 1, 2015, if DOE determines to amend the standards. (42 U.S.C. 6313(d)(3)(A))
