Methodology

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

Scope

The refrigerated vending machines listed:

• are plug-in cabinets (remote cabinets are not considered)
• 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)
• Maximum energy efficiency index of 75

Energy consumption

• Measurement according to European standard for vending machines (EN 50597:2015)
  while measured at 25°C, 60% relative humidity (climate class 3)

Data sources

Data according to the above standards is provided by manufacturers.

Calculation of the energy efficiency index (EEI)

EEI = (AEC/SAEC)*100 = (TEC * 365 / ((M + N * Y) * 365 * P * C)) * 100

TEC = energy consumption over 24h
Vn = net volume in litres
Tv according to the table below

Order of presentation

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

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: 0.3 €/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.

Energy

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

Refrigerant

• R600a (isobutane, climate-friendly refrigerant)
• R290 (propane, climate-friendly refrigerant)
• R744 (CO2, 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.
