Methodology

Topten.eu presents the most energy efficient ice cream freezers on the European market. All listed products use natural climate-friendly refrigerants.

Scope

The ice cream freezers listed:

• are plug-in cabinets (remote cabinets are not considered)
• have maximum 600 litres net volume
• are static
• 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 class C or better (maximum energy efficiency index of 35)
  R744 models with energy class D or better (maximum energy efficiency index of 50)

Energy consumption

• Measurement in climate class 4 (30°C, 55% relative humidity)
• Temperature class must be one of the following: C1 or C2 (EN 16901)
• According to the European standard for ice cream freezers (EN 16901)

Data sources

Data according to the above standards is provided by manufacturers.

Calculation of the energy efficiency index (EEI )

EEI = (AE/SAE)*100 = (TEC * 365 / ((M + N * Y) * 365 * P * C)) * 100

TEC = energy consumption over 24h
Veq = NetVolume * ((12 - Tc)/30) * CC with Tc and CC defined in the tables below

Order of presentation

Products are ranked according to energy efficiency index (EEI). The order of presentation can be changed by selecting the sort order on the upper right corner.

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 and can be shown individually by checking the box "Show Series Products" on top of the list.

Electricity costs

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

• Typical life time: 8 years
• Annual energy consumption: Value from product list in kWh/year
• Tariff of electricity: 0.2 €/kWh (there however can be large differences depending on country or electrical utility)

Total display area

Total display area (TDA) in m2.

Net volume, Gross volume

Net / gross volume in liters.

Storage temperatures

Storage temperature range in °C.

Temperature class

Temperatures measured inside the cabinet during the energy consumption test.

According to the EN 16901 standard for ice cream freezers:

Energy

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

Refrigerant

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.
