Federal Register / Vol. 86, No. 134 / Friday, July 16, 2021 / Proposed Rules long as it does not include any comments.
Include contact information each time you submit comments, data, documents, and other information to DOE. Faxes will not be accepted.
Comments, data, and other information submitted to DOE
electronically should be provided in PDF preferred, Microsoft Word or Excel, WordPerfect, or text ASCII file format. Provide documents that are not secured, written in English, and free of any defects or viruses. Documents should not contain special characters or any form of encryption and, if possible, they should carry the electronic signature of the author.
Campaign form letters. Please submit campaign form letters by the originating organization in batches of between 50 to 500 form letters per PDF or as one form letter with a list of supporters names compiled into one or more PDFs. This reduces comment processing and posting time.
Confidential Business Information.
Pursuant to 10 CFR 1004.11, any person submitting information that he or she believes to be confidential and exempt by law from public disclosure should submit via email two well-marked copies: One copy of the document marked confidential including all the information believed to be confidential, and one copy of the document marked non-confidential with the information believed to be confidential deleted. DOE
will make its own determination about the confidential status of the information and treat it according to its determination.
It is DOEs policy that all comments may be included in the public docket, without change and as received, including any personal information provided in the comments except information deemed to be exempt from public disclosure.
DOE considers public participation to be a very important part of the process for developing test procedures and energy conservation standards. DOE
actively encourages the participation and interaction of the public during the comment period in each stage of this process. Interactions with and between members of the public provide a balanced discussion of the issues and assist DOE in the process. Anyone who wishes to be added to the DOE mailing list to receive future notices and information about this process should contact Appliance and Equipment Standards Program staff at 202 287
1445 or via email at ApplianceStandardsQuestions@

IV. Issues on Which DOE Seeks Comment Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues:
Issue 1: DOE seeks information regarding the thermal transmission through display panels and design characteristics which would affect the thermal transmission, specifically, glass pack design and frame design.
DOE also seeks information regarding the amount of direct electrical energy consumption of electricity-consuming devices sited on or within display panels, including the amount of antisweat heat required, if any. DOE
additionally requests information on any specific design or use characteristics differentiating display panels from display doors.
Issue 2: DOE requests comment on 1
whether there are medium-temperature refrigeration system models that are used exclusively in high temperature freezers, and 2 if a mediumtemperature refrigeration system is efficient for cooler applications, will it also be efficient for use in hightemperature freezer applications. To the extent available, DOE requests data on dedicated condensing unit energy efficiency ratio EER at both hightemperature freezer and mediumtemperature refrigeration operation.
Issue 3: DOE requests data and information on the impact of singlepackage system design limitations on efficiency and how single-package systems differ from split systems. DOE
additionally requests information showing the trend of efficiency as a function of capacity for single-package refrigeration systems.
Issue 4: DOE seeks information on how trends in wine cellar installations e.g., commercial vs. residential, square footage, etc. are expected to impact the type of refrigeration system i.e., singlepackage, matched-pair, dedicated condensing unit, or unit cooler system used in wine cellars over the next 5 to 10 years. Additionally, DOE requests information and data on the extent to which capacity may impact the efficiency of wine cellar refrigeration systems.
Issue 5: DOE seeks input and data as to the daily run-time hours, sizing practice, and ambient conditions for the following: single-package refrigeration systems, high-temperature freezers, and wine cellars described in sections II.A.2
through II.A.4 of this document. DOE
also requests information and data regarding any other aspects of the

operation of such equipment that would influence run-time hours.
Issue 6: DOE seeks input and data on the appropriate PTO values for display doors that would be exposed to higher levels of humidity. Specifically, DOE
requests information on high-humidity walk-in cooler doors, including the range of typical installation conditions e.g., relative humidity throughout the year in store. DOE also requests data on the average amount of time per day or per year that anti-sweat heaters with timers, control systems, or demandbased controls are operating at their full power and partial power if applicable for walk-in cooler display doors marketed for high-humidity applications.
Issue 7: DOE seeks input on whether the combined safety and capacity mismatch oversizing factors for adjusting daily nominal run-time hours relied on in the June 2014 ECS final rule and the July 2017 ECS final rule are appropriate for single-package refrigeration systems, high-temperature freezers, and wine cellars as described in sections II.A.2 through II.A.4 of this document. If different factors would be appropriate for such equipment, DOE
requests data in support of alternate assumptions.
Issue 8: DOE seeks data and information regarding the current, and projected future market shares of WICF
equipment by efficiency level e.g., expressed in terms of increments of 10
percent improvement in AWEF, Rvalues, and kWh/day for refrigeration systems, panels, and doors, respectively, above or below the existing standards in 10 CFR 431.306 to establish market trends in equipment efficiency over time. DOE also seeks information on how the current regulatory environment has affected the market share of WICF
equipment by efficiency rating.
Issue 9: DOE seeks information on how the physical construction of a display door, including the glass pack and the frame, impact the amount of anti-sweat heater wire power needed to prevent condensation accumulating on any part of the door. Specifically, DOE
seeks quantitative data, if available, on the change in anti-sweat heater power 1 with a specific change in door frame design but no change in glass pack design, 2 with a specific change in glass pack design but no change in door frame design, and/or 3 with specific changes to the entire assembly. If there are specific design choices which are more costly but result in less or no antisweat heat, DOE requests cost data based on the capability of the door to prevent condensation from forming and the respective design options chosen.
