What is DOE Certificate?

For the energy and water conservation purpose, the U.S. Department of Energy (DOE) has established standards for certain consumer products and commercial and industrial equipment, including commercial refrigerators & freezers.

In order to implement the current standards fluently for covered appliances and equipment, DOE has published certification, compliance, and enforcement regulations for these products.

There are serious penalties for non-compliance with the DOE certificate of compliance requirements. We’re quite sure that you don’t want to have anything to do with that.

DOE Standard for Commercial Refrigerators & Freezers

Type Standard Sample
Cooler 24-Hour Power Consumption (kWh) ≤ 0.1V+0.86
V = Net Capacity (Cu.Ft)
For a cooler with a net capacity of 12 Cu.Ft, the power consumption of the 24-hour DOE test has to be under 2.06 kWh (0.1×12+0.86)
Freezer 24-Hour Power Consumption (kWh) ≤ 0.29V+2.95
V = Net Capacity (Cu.Ft)
For a freezer with a net capacity of 12 Cu.Ft, the power consumption of the 24-hour DOE test has to be under 6.43 kWh (0.29×12+2.95)

Test Procedures of DOE Certificate

  • Each layer of the fridge must put a load, and the load accounts for 70% -90% of the space of each layer.

  • Adjust the thermostat so that the average temperature in the cabinet reaches 38 ± 2 °F (for coolers) or 0 ± 2 °F (for freezers)  Start the test once the operation got stable.

  • Defrost for 3 hours.

  • Then conduct an 8-hour door open test. Open the door every 10 minutes, the door has to be fully open (greater than 75 degrees) every time. Open for 2 seconds, hold for 6 seconds, and close for 2 seconds. A total of 48 times.

  • After the door open test is completed, continues to run the fridge for 13 hours.

  • Finally, add up the 24-hour power consumption (3+8+13 = 24h), and check whether it meets the DOE certificate standard.
