Selection Criteria for Beverage Coolers

Methodology

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

Scope

The beverage coolers listed:

• are plug-in cabinets (remote cabinets are not considered)
• have forced-air circulation or are capable of pulling down temperature within 4 hours, respectively
• 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 EEI of 35) / R744 models with class D or better (maximum EEI of 50)
• The devices must not be ‘open’. This means they have doors or a lid.

Energy consumption

• According to the European standard for beverage coolers (EN 16902)
• Measurement at CC1 (EN 16902) / climate class 3 (EN ISO 23953) -> both at 25°C, 60% relative humidity
• Temperature class must be one of the following: K1, K2, K3 or K4 (EN 16902); M1 or M2 (EN ISO 23953)

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 = GrossVolume * ((25-Tc)/20) * 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 top right above the lists.

Glossary

Brand, Model, Series products

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: 0.3 €/kWh (there however can be large differences depending on country or electrical utility)

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 16902 standard for beverage coolers:

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

Ambient temperature

Suitable ambient temperature range in °C as recommended by the manufacturer.

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.
