ENERGY STAR® – Qualifying Criteria for Refrigerators, Refrigerator-Freezers and Freezers

Refrigerators, refrigerator-freezers and freezers must meet Canada's Energy Efficiency Regulations before they can qualify for the ENERGY STAR symbol in Canada.

Definitions

Refrigerators and Refrigerator-Freezers (Residential): Standard-Size
(Types 1, 2, 3, 4, 5, 5A, 6, 7)

All-refrigerators and refrigerator-freezers with a total volume greater than or equal to 219.5 L (7.75 cu. ft.) but less than or equal to 1104.4 L (39 cu. ft.).

Freezers (Residential): Standard-Size
(Type 8, 9, 10, 10A)

Freezers with a total volume greater than or equal to 219.5 L (7.75 cu. ft.) but less than or equal to 850.5 L (30 cu. ft.).

Refrigerators, Refrigerator-Freezers and Freezers (Residential): Compact
(Type 11, 12, 13, 14, 15, 16, 17, 18)

All compact refrigerators, refrigerator-freezers and freezers with a total volume less than 219.5 L (7.75 cu. ft.) and an overall height less than 91.4 cm (36 inches).

Test Standard

Test Criteria for ENERGY STAR in Canada is harmonized with Test Criteria for ENERGY STAR in the United States:

Test Criteria for ENERGY STAR: Residential refrigerator manufacturers must test their equipment according to the US Department of Energy's test procedure defined in 10 CFR 430, Subpart B, Appendix A1. Residential freezer manufacturers must test their equipment according to the test procedure defined in 10 CFR 430, Subpart B, Appendix B1. When determining energy performance for purposes of ENERGY STAR certification, the following principles of interpretation should be applied to the existing DOE test procedures. The energy test procedure simulates typical room conditions (approximately 70°F) with door openings, by testing at 90°F without door openings.

Except for operating characteristics that are affected by ambient temperature (for example, compressor percent run time), the unit, when tested under the DOE test procedure, shall operate equivalent to the unit in typical room conditions. Energy consuming components that operate in typical room conditions (including as a result of door openings, or in response to humidity levels), and that are not exempted by this standard, shall operate in an equivalent manner during energy testing under the DOE test procedure, or be accounted for by all calculations as provided for in the standard. Examples: (i) energy saving features that are designed to operate when there are no door openings for long periods of time shall not be functional during the energy test; (ii) the defrost heater should not either function or turn off differently during the energy test than it would when in typical room conditions; (iii) electric heaters that would normally operate at typical room conditions with door openings should also operate during the energy test; and (iv) energy used during adaptive defrost shall continue to be tested and adjusted per the calculation provided for in this standard.

Criteria

To determine whether a model qualifies,

1) Calculate the adjusted volume (AV),
AV = Vfresh food + (Vfreezer x Adjustment Factor (AF))
 Where
Vfresh food is the volume of the fresh food compartment of a refrigerator in cubic feet.
Vfreezer is the volume of the freezer compartment of a refrigerator in cubic feet.
Adjustment Factor (AF)
For all-refrigerators* AF = 1.00
For basic refrigerators** AF = 1.44
For combination refrigerator-freezers AF = 1.63
For freezers AF = 1.73
* All-refrigerator – a refrigerator that does not include a compartment for the storage of food at temperatures below 0° C (32°F). It may include a compartment of 14.2 L (0.5 cu. ft.) or less for the freezing and storage of ice.
** Basic refrigerator – in general, not a refrigerator-freezer nor an all-refrigerator. It is characterized by a refrigerated surface that partially encloses the low-temperature compartment and cools the fresh food compartment by natural convection. It frequently has a partition (called the chiller or drip tray).
2) Based on the type and adjusted volume of the model, compare the model's annual energy consumption with the annual energy consumption calculation from the correct table below. To be ENERGY STAR qualified, the model's annual energy consumption must be less than the calculated value.
