Energy Efficiency Program for Certain Commercial and Industrial Equipment: Test Procedures for Automatic Commercial Ice Makers

Краткое содержание

The U.S. Department of Energy (DOE) proposes to revise its test procedure for automatic commercial ice makers (ACIM) established under the Energy Policy and Conservation Act. This notice of proposed rulemaking (NOPR) proposes to update the incorporation by reference of industry test procedures to the most current published versions. The current DOE test procedure applies to automatic commercial ice makers that produce cube type ice. This NOPR proposes to expand coverage of the test procedure to all batch type and continuous type ice makers with capacities between 50 and 4,000 pounds of ice per 24 hours. A batch type ice maker is defined as an ice maker with alternate freezing and harvesting periods, including machines that produce cube type ice, tube type ice, and fragmented ice. A continuous type ice maker is defined as an ice maker that continually freezes and harvests ice at the same time. Continuous type ice makers primarily produce flake or nugget ice. DOE also proposes amendments to standardize test results based on ice quality for continuous type ice makers, clarify the test methods and reporting requirements for automatic ice makers designed to be connected to a remote comp
