Federal Register / Vol. 86, No. 134 / Friday, July 16, 2021 / Proposed Rules
Issue 36: DOE requests comment on if the capacity, AWEF, condenser fan power, and compressor types provided by AHRI are representative of the market for single-package and matchedpair wine cellar refrigeration systems.
DOE also seeks information on the availability and prevalence of wine cellar refrigeration systems between 13,000 and 18,000 Btu/h for walk-in wine cellars with a square footage of 3,000 square feet or less.
Issue 37: DOE seeks comment on whether the distribution channels used in the June 2014 ECS final rule and July 2017 ECS final rule as depicted in Table II.16 remain relevant today, and if not, DOE requests information on these channels as well as the existence of any additional channels that are used to distribute walk-in components into the market. Additionally, DOE requests comment on the appropriateness of these channels, and their respective fractions for the following equipment:
display-panels, high-temperature freezers, single-package refrigeration systems, and wine cellars as described in sections II.A.1 through II.A.4 of this document.
Issue 38: DOE seeks comment on its estimated equipment lifetime for WICF
refrigeration system and envelope components. Specifically, DOE requests data on appropriate average lifetimes that DOEs analyses should use for:
Display-panels, high-temperature freezers, single-package refrigeration systems, and wine cellars as described in sections II.A.1 through II.A.4 of this document.
Issue 39: DOE requests comment on its assumption that the market share of shipments for each equipment class would remain constant over time.
Issue 40: DOE seeks input from stakeholders on whether the shipments shown for low-temperature dedicated condensing equipment and unit coolers are still relevant. Further, DOE seeks data on the annual shipments of lowtemperature single-package refrigeration systems see section II.A.3 of this document and the distribution of rated capacities as shown in Table II.15 of this document.
Issue 41: DOE seeks input from stakeholders on whether the shipments shown for medium-temperature condensing equipment and unit coolers reflect the state of the current market.
Issue 42: DOE seeks data on the annual shipments of mediumtemperature single-package refrigeration systems see section II.A.3 of this document, high-temperature freezers see section II.A.2 of this document and wine cellar refrigeration systems see section II.A.4 of this document and the

distribution of rated capacities of each Btu/h. DOE also seeks data on the fraction of high-temperature freezers and wine cellar refrigeration systems that are sold as single-package, manufacturer matched-pair or split systems. Additionally, DOE requests data on the relative market size of refrigeration systems used in high temperature freezers compared to the refrigeration system market sizes for cooler applications i.e., temperature greater than 32 F and low-temperature e.g., less than or equal to 10 F
freezer applications.
Issue 43: DOE requests data on the fraction of low-temperature and medium-temperature panels that are installed outdoors versus indoors.
Additionally, DOE requests data on the fraction of low-temperature and medium-temperature freight and passage doors that are installed outdoors versus indoors.
Issue 44: DOE seeks input from stakeholders on whether the shipments shown for panels and doors reflect the state of the current market. Further, DOE seeks data on the annual shipments, in terms of units shipped, of low-temperature and mediumtemperature display panels described in section II.A.1 of this document.
Issue 45: DOE also requests specific information on high-humidity mediumtemperature display door shipments see section II.C.1.a of this document and their fraction of annual display door shipments.

Energy Conservation Program: Energy Conservation Standards for Certain Commercial and Industrial Equipment;
Early Assessment Review; Commercial Refrigerators, Freezers, and Refrigerator-Freezers Office of Energy Efficiency and Renewable Energy, Department of Energy.
ACTION: Request for information.
AGENCY:

The U.S. Department of Energy DOE or the Department is undertaking an early assessment review for amended energy conservation standards for commercial refrigerators, freezers, and refrigerator-freezers CRE to determine whether to amend applicable energy conservation standards for this equipment.
Specifically, through this request for information RFI, DOE seeks data and information to evaluate whether amended energy conservation standards would result in significant savings of energy; be technologically feasible; and be economically justified. DOE
welcomes written comments from the public on any subject within the scope of this document including those topics not specifically raised in this RFI, as well as the submission of data and other relevant information concerning this early assessment review.
DATES: Written comments and information are requested and will be accepted on or before August 30, 2021.
ADDRESSES: Interested persons are encouraged to submit comments using the Federal eRulemaking Portal at https www.regulations.gov. Follow the instructions for submitting comments.
Alternatively, interested persons may submit comments, identified by docket number EERE2017BTSTD0007, by any of the following methods:
1. Federal eRulemaking Portal:
https www.regulations.gov. Follow the instructions for submitting comments.
2. Email: to CRE2017STD0007@
ee.doe.gov. Include docket number EERE2017BTSTD0007 in the subject line of the message.
