Selection Criteria Storage Refrigerators and Freezers

Methodology

Topten.eu presents the most energy efficient professional storage refrigerators and freezers on the European market. All listed products use natural climate-friendly refrigerants.

Scope

The products listed:

• are plug-in cabinets (remote cabinets are not considered)
• are storage cabinets (not for the display to and access by customers)
• are available on the European market

Technical criteria

All models on Topten.eu meet the following criteria:

• Natural refrigerant with global warming potential (GWP) ≤ 3 (e.g. R290/propane, R600a/isobutane, R744/CO2)
• Energy efficiency index (EEI) according to EU regulation 2015/1094 not higher than given in the following table.

Addition to the technical criteria: Storage refrigerator-freezers and static storage cabinets are exempt from the EU energy label. In the Topten product lists they can nevertheless be listed, under the condition that their energy consumption is determined according to the here mentioned harmonised testing standards. With the standard values, the energy efficiency index EEI can be calculated according to the EU energy label in the same way as for the other cabinets. Storage refrigerator-freezers are to be classified as vertical freezers for the calculation.

Topten accepted test standards

The test standards for the declaration of the energy consumption of storage refrigerators and freezers are regulated in EU regulation 2015/1094. Topten accepted standards for storage refrigerator-freezers and static storage cabinets can be found here.

Glossary

Brand, Model, Other models

Brand with link to website. All other models (different sizes etc.) that are named meet the Topten technical criteria as well.

Electricity costs

Costs for electricity during product's life time. Assumptions:

• Typical life time: 8 years
• Annual energy consumption: Calculated according to EU energy label in kWh/year
• Tariff of electricity: 0.3 €/kWh (there however can be large differences depending on country or electrical utility)

Net volume

Net volume in liters.

Storage temperatures

Storage temperature range in °C.

Climate class

Energy efficiency class

Energy efficiency class according to EU regulation 2015/1094. Most efficient is A+++ (no products available yet), least efficient is G. Class G products have not not permitted on the market since January 2018. Class F products are banned since 1.Juli 2019 (with the exemption of heavy-duty products).

Classes in parentheses are "energy-class-equivalents" for products that are not covered by the scope of the official regulation - such as static storage appliances - but have been tested according to EN16825.

Energy efficiency index

Energy efficiency index (EEI) according to EU regulation 2015/1094. Value in percent (%). The lower the value, the more efficient the product.

Energy

Annual energy consumption in kWh/year. Accepted measuring protocols see above.

Refrigerant

• R600a (isobutane, natural climate-friendly refrigerant)
• R290 (propane, natural climate-friendly refrigerant)
• R744 (CO2, natural climate-friendly refrigerant)
• Inefficient models: R134a, R404A or R507 (fluorinated refrigerants with high global warming potential)

Cooling

• Static
• Forced-air

Dimensions

Width x depth x height in cm.

Countries available

This item displays the availability of models in European countries according to producers’ information. "EU" means that the model is available in all or most European countries. If the model is available in a number of countries only they are indicated by country codes according to ISO. "On demand" means that producers could not indicate the availability and that consumers have to ask in their countries on their own.
