Mixed Solid/Glass Door Cabinets

For mixed solid/glass door cabinets designed with two or more compartments contained in a single cabinet, with different exterior door types (i.e., one is glass and one is solid) on the same side of the cabinet, the MDEC shall be the sum of all individual compartment MDEC values.

Testing Procedures:

Manufacturers must use ANSI/ASHRAE Standard 72-2005, Method of Testing Commercial Refrigerators and Freezers, to measure the daily energy consumption of commercial food-grade refrigerators and freezers using the integrated average temperature specifications in the program requirements.

Additional third-party certification is required, to applicable requirements set forth in the following quality and safety standards:

  • ANSI/NSF International Standard for Food Equipment - Commercial Refrigerators and Freezers (ANSI/NSF 7-2007); and
  • UL Standard for Commercial Refrigerators and Freezers (UL-471).

Definitions:

Only those products that meet definitions below are eligible for ENERGY STAR qualification. Examples of product types that may be eligible for qualification include: reach-in, roll-in, or pass-through units; merchandisers; undercounter units; milk coolers; back bar coolers; bottle coolers; glass frosters; deep well units; beer-dispensing or direct draw units; and bunker freezers.

Drawer cabinets, prep tables, deli cases, and open air units are not eligible for ENERGY STAR under the Version 2.0 specification. This specification is intended for commercial food-grade refrigeration equipment only. Laboratory-grade refrigeration equipment cannot qualify for ENERGY STAR under this Version 2.0 specification.

Commercial Food-grade Refrigerator

A refrigeration cabinet designed for storing food products at temperatures above 32 degrees Fahrenheit (F) but no greater than 40 degrees F and intended for commercial use.

Commercial Food-grade Freezer

A refrigeration cabinet designed for storing food products at temperatures of 0 degrees F and intended for commercial use.

Refrigeration Cabinet

A refrigerator or freezer used for storing food products at specified temperatures, with the condensing unit and compressor built into the cabinet, and designed for use by commercial or institutional facilities, other than laboratory settings. These units may be vertical or chest configurations and may contain a worktop surface.

Solid Door Cabinet

A commercial food-grade refrigerator or freezer in which all outer doors on all sides of the unit are solid doors. These doors may be sliding or hinged.

Glass Door Cabinet

A commercial food-grade refrigerator or freezer in which all outer doors on at least one side of the unit are glass doors. These doors may be sliding or hinged.

Mixed Solid/Glass Door Cabinet

A commercial food-grade refrigerator or freezer in which all outer doors on at least one side of the unit is a combination of solid and glass doors. A unit which has all glass doors on one side and a combination of solid and glass doors on another is considered a glass door cabinet.
