Quick Facts on Refrigerators, Refrigerator-Freezers and Freezers

Today's refrigerators, refrigerator-freezers and freezers are about 50 percent more energy efficient than they were in 1990, and ENERGY STAR® qualified models are even better.

Improvements in energy efficiency have been particularly impressive for refrigerators and freezers. Superior design and technological developments (e.g., improved condensers, compressors, evaporators, fan motors, door seals and foam insulation) have all helped to improve energy efficiency.

What does "type" mean on the EnerGuide label for refrigerators, refrigerators-freezers and freezers?

Every EnerGuide label lists the type of product, its capacity and its energy consumption. It does not list other features because of space restrictions; instead, the type of product is shown by a number. The chart below lists the types of refrigerators, refrigerator-freezers and freezers, with their corresponding features. After you get to know them, you will be able to explain to your customers what each type means.

Type Main features

  1. Refrigerators and refrigerator-freezers with manual defrost
  2. Refrigerator-freezers with partial automatic defrost
  3. Refrigerator-freezers with automatic defrost and top-mounted freezer, without through-the-door ice service; all refrigerators without freezers but with automatic defrost
  4. Refrigerator-freezers with automatic defrost and side-mounted freezer, without through-the-door ice service
  5. Refrigerator-freezers with automatic defrost and bottom-mounted freezer, without through-the-door ice service
  6. Refrigerator-freezers with automatic defrost, top-mounted freezer and through- the-door ice service
  7. Refrigerator-freezers with automatic defrost, side-mounted freezer and through- the-door ice service
  8. Upright freezers with manual defrost

Testing today (CSA Standard C300-00)

Note: This test standard is also used as the basis for verifying energy performance for ENERGY STAR qualified products.

Refrigerators, refrigerator-freezers and freezers of all types – with automatic defrost, partial automatic defrost, different freezer sections, through-the-door ice service, etc. – undergo energy consumption tests.

Energy consumption is tested at two different thermostat settings. The test period takes between 3 and 24 hours for each thermostat setting, depending on whether the appliance has manual or automatic defrost. Separate tests using 300 gram frozen spinach packages are done for refrigerator-freezers and freezers with manual defrost. For the refrigerator compartment, a series of thermocouples are used to ensure that the temperature is maintained as per the test procedure. The freezer compartments are loaded to 75 percent capacity with the spinach packages. Electric thermometers inside the packages determine the average freezer temperature.

The regulated minimum energy efficiency levels for all refrigerators, refrigerator-freezers and freezers in Canada have been the same as those of the United States since January 1, 2003.

Calculating the EnerGuide Rating

Energy consumption during the test period is measured and then converted into a daily 24-hour consumption value. This in turn is multiplied by 365 to get an average annual energy consumption value. This is the value on the EnerGuide label.

For example:

0.96 kWh      ×
(energy consumption
during test period)
8760      =
(24 h/day
×
365 days/years)
416 kWh/year
(annual energy
consumption)

4.13 (test period time in hours)
