Commission Delegated Regulation (EU) 2019/2018 of 11 March 2019 supplementing Regulation (EU) 2017/1369 of the European Parliament and of the Council with regard to energy labelling of refrigerating appliances with a direct sales function (Text with EEA relevance)
Pan adawodd y DU yr UE, cyhoeddodd legislation.gov.uk ddeddfwriaeth yr UE a gyhoeddwyd gan yr UE hyd at ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.). Ar legislation.gov.uk, mae'r eitemau hyn o ddeddfwriaeth yn cael eu diweddaru'n gyson ag unrhyw ddiwygiadau a wnaed gan y DU ers hynny.
Roedd y fersiwn hon o'r Rheoliad hwn yn deillio o EUR-Lex ar ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11: 00 p.m.). Nid yw wedi cael ei diwygio gan y DU ers hynny. Darganfyddwch fwy am ddeddfwriaeth sy'n deillio o'r UE fel y'i cyhoeddwyd ar legislation.gov.uk.
For the purposes of compliance and verification of compliance with the requirements of this Regulation, measurements and calculations shall be made using harmonised standards, or other reliable, accurate and reproducible methods, which take into account the generally recognised state-of-the-art methods and are in line with the following provisions set out below. The reference numbers of these harmonised standards have been published for this purpose in the Official Journal of the European Union.
the ambient conditions shall correspond to Set 1, except for ice-cream freezers and gelato scooping cabinets which shall be tested in ambient conditions corresponding to Set 2, as set out in Table 2.
where a compartment can be set to different temperatures, it shall be tested at the lowest operating temperature.
refrigerated vending machines with compartments with variable volumes shall be tested with the net volume of the compartment with the highest operating temperature adjusted to its minimum net volume.
for beverage coolers, the specified cooling speed shall be according to the half reload recovery time.
Ambient conditions
| Dry bulb temperature, °C | Relative humidity, % | Dew point, °C | Water vapour mass in dry air, g/kg | |
|---|---|---|---|---|
| Set 1 | 25 | 60 | 16,7 | 12,0 |
| Set 2 | 30 | 55 | 20,0 | 14,8 |
For all refrigerating appliances with a direct sales function, the EEI, expressed in % and rounded to the first decimal place, is the ratio of the AE (in kWh/a) and the reference SAE (in kWh/a) and is calculated as:
EEI = AE/SAE.
The AE, expressed in kWh/a and rounded to two decimal places, is calculated as follows:
AE = 365 × Edaily ;
with:
Edaily is the energy consumption of the refrigerating appliance with a direct sales function over 24 hours, expressed in kWh/24h and rounded to three decimal places.
The SAE is expressed in kWh/a and rounded to two decimal places. For refrigerating appliances with a direct sales function with all compartments having the same temperature class and for refrigerated vending machines, the SAE is calculated as follows:
SAE = 365 × P × (M + N × Y) × C;
For refrigerating appliances with a direct sales function with more than one compartment having different temperature classes, with the exception of refrigerated vending machines, the SAE is calculated as follows:
where:
c is the index number for a compartment type ranging from 1 to n, with n being the total number of compartment types.
The values of M and N are given in Table 3.
M and N values
| Category | Value for M | Value for N |
|---|---|---|
| Beverage coolers | 2,1 | 0,006 |
| Ice-cream freezers | 2,0 | 0,009 |
| Refrigerated vending machines | 4,1 | 0,004 |
| Gelato-scooping cabinets | 25,0 | 30,4 |
| Vertical and combined supermarket refrigerator cabinets | 9,1 | 9,1 |
| Horizontal supermarket refrigerator cabinets | 3,7 | 3,5 |
| Vertical and combined supermarket freezer cabinets | 7,5 | 19,3 |
| Horizontal supermarket freezer cabinets | 4,0 | 10,3 |
| Roll-in cabinets (from 1 March 2021) | 9,2 | 11,6 |
| Roll-in cabinets (from 1 September 2023) | 9,1 | 9,1 |
The values of C, the temperature coefficient are given in Table 4.

Coefficient Y is calculated as follows:
for beverage coolers:
Yc is the equivalent volume of the compartments of the beverage cooler with target temperature Tc, (Veq c), calculated as follows:
Yc = Veq c = GrossVolumec × ((25 - Tc)/20) × CC;
where Tc is the average compartment classification temperature of the compartment and CC is the climate class factor. The values for Tc are set out in Table 5. The values for CC are set out in Table 6.
Temperature classes and corresponding average compartment temperatures (Tc) for beverage coolers

for ice-cream freezers:
Yc is the equivalent volume of compartments of the ice-cream freezer with target temperature Tc, (Veq c), calculated as follows:
Yc = Veq c = NetVolume × ((12 - Tc)/30) × CC;
where Tc is the average compartment classification temperature of the compartment and CC is the climate class factor. The values for Tc are set out in Table 7. The values for CC are set out in Table 8.
Temperature classes and corresponding average compartment temperatures (Tc) for ice-cream freezers

for refrigerated vending machines:
Y is the net volume of the refrigerated vending machine, which is the sum of the volumes of all compartments within which the products directly available for vending are contained and the volume through which the products pass during the dispensing process, expressed in litres (L) and rounded to the nearest integer.
for all other refrigerating appliances with direct sales function:
Yc is the sum of the TDA of all compartments of the same temperature class of the refrigerating appliance with a direct sales function, expressed in square meters (m2), and rounded to two decimal places.
The values for P are set out in Table 9.
