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
  • have doors (because open cabinets cannot meet the efficiency criteria)
  • are available on the European market

Technical criteria

All models on Topten.eu meet the following criteria:

  • Natural refrigerant with global warming potential (GWP) below 3 (e.g. R290/propane, R600a/isobutane, R744/CO2)
  • Maximum draft energy index of 30
    R744 models with a maximum draft energy index of 50

Energy consumption

  • Measurement at climate class 3 (25°C, 60% relative humidity)
  • Temperature class must be one of the following: M1 or M2 (EN ISO 23953); K1, K2, K3 or K4 (EN 16902)
  • Primarily according to the new European standard for beverage coolers (EN 16902)
  • In a transitional phase, measurements are also accepted according to: 
    • EN ISO 23953-2:2005 /A1:2012
  • In a transitional phase, the temperature class requirement does not apply to models submitted before May 2015

Data sources

Data according to the above standards is provided by manufacturers.

Calculation of the draft energy index (EEI)

EEI = (AEC/SAEC)*100 = (TEC * 365 / ((M + N * Y) * 365 * C)) * 100
Category Value for M Value for N Value for Y Value for C
Beverage coolers 1.0 0.013 V 1
TEC = energy consumption over 24h
V = net volume in litres

Order of presentation

Products are ranked according to draft energy index. The order of presentation can be changed by clicking on the rows' headings. Compare models by checking them and clicking on compare.

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: 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)

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 prEN 16902 standard for beverage coolers:
K1 0°C to +7°C, ø <= +3.5°C
K2 -1°C to +6°C, ø <= +2.5°C
K3 -3.5°C to +1°C, ø <= -1°C
K4 +1°C to +9°C, ø <= +5°C
S other
According to EN ISO 23953:
M1 -1°C to +5°C
M2 -1°C to +7°C

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.
