The programme scope covers Remote Refrigerated Display Cabinets (RRDC) intended to be used in retail applications and using natural refrigerant R744 (CO2).
Exclusions: Cabinets with wooden parts that affect performance are excluded. Cabinets operated only with other fluids than R744 (CO2) are excluded too.
Refrigerated Display Cabinet (RDC): Cabinet cooled by a refrigerating system which enables chilled and frozen foodstuff placed therein for display to be maintained within prescribed temperature limits.
Remote Refrigerated Display Cabinet (RRDC): Refrigerated Display Cabinet connected to a remote refrigerating unit.
Product family: Group of cabinets in accordance with the standard terminology Annex A of EN ISO 23953-1:2015
M-package temperature class: Classification of M-package temperature according to temperatures of warmest and coldest M-packages during the temperature test according to the table 1 of standard EN ISO 23953-2:2015. For cabinets with night covers and lighting the M-package temperature class is only based on the second test part b) of EN ISO 23953-2:2015 chapter 126.96.36.199.2 with 12 hours day and 12 hours night.
Refrigeration Electrical energy Consumption (REC) [kWh/day]: According to EN ISO 23953-2:2015 chapter 188.8.131.52.3, calculated with the following formula:
Direct Electrical Energy Consumption (DEC) with 12h lighting [kWh/day]: According to EN ISO 23953-2:2015 chapter 5.3.5.
TEC: for remote cabinets, TEC is the sum of REC and DEC
TECRemote = REC + DEC
Total Display Area (TDA) [m2]: According to EN ISO 23953-2:2015 Annex A rounding all terms in the formula to the second decimal.
Energy Efficiency Index (EEI) : According to regulation (EU) 2019/2024, the Energy Efficiency Index (EEI) means an index number for the relative energy efficiency of a refrigeration appliance with a direct sales function expressed in percentage [%] and rounded to the first decimal place. It is the ratio of AE [in kWh/a] and the reference SAE [in kWh/a] and is calculated as:
Annual Energy Consumption (AE): According to regulation (EU) 2019/2024, the Annual Energy Consumption (AE) means the average daily energy consumption Edaily (see §I.3.7) multiplied by 365 (days per year) expressed in kilowatt hour per year [kWh/a] and rounded to two decimal places.
Standard Annual Energy Consumption (SAE): According to regulation (EU) 2019/2024 the Standard Annual Energy Consumption (SAE) means the reference annual energy consumption of a refrigeration appliance with a direct sales function expressed in kilowatt hour per year [kWh/a] with all compartments having the same temperature class and rounded to two decimal places.
