Understanding new capacity and energy ratings

 

From 15th August 2021, the way refrigerators & freezers are tested to calculate energy consumption and capacity has changed to comply with new MEPS standards.

This means that the capacity and energy ratings have changed too.

 

What is MEPS?

MEPS stands for minimum energy performance standards. The new testing methodology adopts the International Electrotechnical Commission (IEC) 62552-3:2015 test standard for household refrigerators and freezers, and introduces new MEPS for household refrigerators and freezers.

This change is detailed in the Energy Modelling Methodology for MEPS 2021 Compliance - July 2020 document which can be found here.

 

What has changed in regard to energy consumption testing?

Testing methods have changed and will now be conducted at 16 degrees Celsius and 32 degrees Celsius instead of only at 32 degrees Celcius. This simulates a typical homes temperature environment.

As a result, energy consumption ratings (measured in kwhr/year) may be lower than the current published figures and may have an overall impact in the energy star rating too.

 

What has changed in regard to capacity calculations?

Historically, both gross capacity (measured in litres) and net capacity (also measured in litres) have been used to describe refrigerator or freezer capacity. Gross capacity is the total space in a refrigerator or freezer, while net capacity is the usable space within the refrigerator or freezer.

This will now be replaced with one capacity number. It will measure what you can see inside the product and will not measure the space behind the panel and ducts.

As a result, published capacities of some refrigerators and freezers may change, with many showing a lesser capacity than what is currently published. It’s important to note that this does not mean less space in the refrigerator, or even any changes to the existing model, just a different way of calculating capacity.

How can tell which fridge is measured in the new ratings & capacities?

From 15 August 2021 all refrigerators manufactured or imported must comply with the new Minimum Energy Performance Standards (MEPS), however products manufactured or imported before this date that do not meet new MEPS can be sold by suppliers indefinitely.

This means that you may have 2 identical products in-store side by side with varying capacities and energy ratings. The products will be the same, one will have been manufactured before 15 August 2021, and the other post that date. There are no physical changes to the product, and the model SKU will remain unchanged.

Attached is a full list of before and after capacities and energy ratings for products that have been affected by this change.
