Energy Efficiency Regulations

Technical Requirements for Energy-Using Products

Applies to

Self-contained commercial refrigerator

  1. has at least one compartment for the storage of food and beverages at temperatures above 0°C;
  2. has no more than one compartment for the freezing and storage of food and beverages at temperatures between 0°C and -13.3°C; and
  3. has a self-contained refrigeration system that requires energy input;

but does not include

  • a refrigerated buffet table, a commercial refrigerator that is designed to function as a table or counter for receiving and refrigerating food and from which persons can serve themselves, and that uses a mechanical refrigeration system;
  • a refrigerated preparation table, a commercial refrigerator the top of which is a work surface on which food can be prepared, displayed and kept refrigerated at temperatures between 1°C and 5°C; or
  • a walk-in commercial refrigerator.

Self-contained commercial freezer

  1. all the compartments are designed for the freezing and storage of food, beverages or ice; and
  2. has a self-contained refrigeration system that requires energy input;

but does not include

  • a walk-in commercial freezer.

Self-contained commercial refrigerator-freezer

  1. has two or more compartments, at least one of which is for the storage of food and beverages at temperatures above 0°C and at least one other which is for the freezing and storage of food and beverages at temperatures below -13.3°C; and
  2. has a self-contained refrigeration system that requires energy input;

but does not include

  • a walk-in commercial freezer.

Compliance Date

Test Standard (Method)

ASHRAE standard 117-1992, Method of Testing Closed Refrigerators

  • self-contained commercial refrigerators with doors or drawers
  • self-contained commercial freezers with doors
  • self-contained refrigerator-freezers – all

except that

  1. the liquid used in the test packages may be either a solution of salt and water (H2O and 6% +/- 0.5% NaCl by mass) or a mixture that, by volume, is equal parts propylene glycol and distilled water;
  2. if the product features a roll-through or pass-through cabinet, the testing shall be conducted with the rear doors of the cabinet in the closed position; and
  3. testing to determine the Edaily shall be conducted

    1. with the goods in each refrigerator compartment at a temperature of 3.3°C +/- 1.1°C, but if a refrigerator compartment is designed solely for the cooling and storage of wine, the goods in that compartment shall be at a temperature of 7.2°C +/- 1.1°C, and
    2. with the goods in each freezer compartment at a temperature of -17.8°C +/- 1.1°C, but if a freezer compartment is designed solely for the storage or dispensing of ice cream or similar foods, the goods in that compartment shall be at a temperature of -20.6°C +/- 1.1°C.

ASHRAE standard 72-1998, Method of Testing Open Refrigerators

  • self-contained commercial refrigerators without doors or drawers

except when determining the Edaily for commercial refrigerators without doors or drawers goods in the refrigerator compartment are at a temperature of 3.3°C +/- 1.1°C

  • self-contained commercial freezers without doors

* Product has no energy efficiency performance requirements but must meet all other regulatory requirements.

Notes:

  1. "AV" means the adjusted volume of the product in litres calculated as follows:
    AV = the refrigerator volume in litres + 1.63 × the freezer volume in litres.
  2. "Edaily" means the daily energy consumption of the product expressed in kilowatt hours per day.
  3. "V" means the volume in litres of the refrigerated compartment.
  4. Use AHAM standard ANSI/AHAM HRF-1-2004 entitled Energy Performance and Capacity of Household Refrigerators, Refrigerator-Freezers and Freezers to calculate refrigerator or freezer compartment volumes.
