Regulations 7(2), 8(2)(d) and 12(b)
1.—(1) An appliance shall be classified as A+ or A++ where the energy efficiency index alpha (I) is within the ranges specified in Table 1.U.K.
Energy efficiency index α(Iα) | “Energy efficiency class” |
---|---|
30 > Iα | A++ |
42 > Iα ≥ 30 | A+ |
Iα ≥ 42 | A to G (see below) |
(2) The energy efficiency index alpha shall be calculated using the formula:
where—
“AC” means the annual energy consumption of the appliance (in accordance with the harmonised standards); and
“SCα” means the standard annual energy consumption α of the appliance.
“SCα” is calculated as:
where—
“Vc” means the net volume (in litres) of the compartment (in accordance with the harmonised standards);
“Tc” is the design temperature (in °C) of the compartment;
the values of M and N are given in Table 2; and
the values of FF, CC, BI and CH are given in Table 3.
Type of appliance | Temperature of coldest compartment | Mα | Nα |
---|---|---|---|
(1) For these appliances, the temperature and star rating of the compartment with the lowest temperature will determine the values of M and N. Appliances with –18°C *(***) compartments shall be considered as fridge-freezers *(***). | |||
1. Larder Fridge | >-6°C | 0.233 | 245 |
2. Refrigerator/chillers | >-6°C | 0.233 | 245 |
3. Refrigerator no star | >-6°C | 0.233 | 245 |
4. Refrigerator* | ≤-6°C * | 0.643 | 191 |
5. Refrigerator** | ≤-12°C ** | 0.450 | 245 |
6. Refrigerator***/ | ≤-18°C ***/*(***) | 0.777 | 303 |
7. Fridge/freezer *(***) | ≤-18°C ***/*(***) | 0.777 | 303 |
8. Upright freezer | ≤-18°C *(***) | 0.539 | 315 |
9. Chest freezer | ≤-18°C *(***) | 0.472 | 286 |
10. Multi-door or other appliance | (1) | (1) |
Correction factor | Value | Conditions |
---|---|---|
(1) An appliance is “built-in” only if it is designed exclusively for installation within a kitchen cavity with a need of furniture finishings, and tested as such. | ||
FF (frost free) | 1.2 1 | For “frost free” (ventilated) frozen food compartments; Otherwise |
CC (climate class) | 1.2 1.1 1 | For “tropical” appliances; For “subtropical” appliances; Otherwise |
BI (built-in) | 1.2 1 | For built-in appliances (1) of under 58cm in width; Otherwise |
CH (chill compartment) | 50 Kwh/y 0 | For appliances with a chill compartment of at least 15 litres; Otherwise |
(3) If an appliance is not A+ or A++, it shall be classified in accordance with Part 2.
2. The energy efficiency class of an appliance shall be determined in accordance with Table 4.U.K.
Energy efficiency index: I | Energy efficiency class |
---|---|
I < 55 | A |
55 ≤ I < 75 | B |
75 ≤ I < 90 | C |
90 ≤ I < 100 | D |
100 ≤ I < 110 | E |
110 ≤ I < 125 | F |
125 ≤ I | G |
where—
“energy efficiency index” (expressed as a percentage) = annual energy consumption of appliance in accordance with the harmonised standards / standard annual energy consumption of appliance;
“standard annual energy consumption of appliance” (expressed in kWh/year) = M × adjusted net volume + N;
“adjusted net volume” (expressed in litres) = net volume of fresh food compartment + Ω × net volume of frozen food compartment; andthe values of M, N and Ω are taken from Table 5.
Category of Appliance | Ω | M | N |
---|---|---|---|
(1) For refrigerator/chiller the adjusted volume = net volume of fresh food compartment + Ω × net volume of chiller (10°C) compartment (expressed in litres). | |||
(2) For ‘no frost’ appliances as defined in the harmonised standards, this index is increased by a provisional factor of 1.2 giving a value of 2.58 (this allows for the possible bias of the measurement method, which does not allow for the lack of ice build-up on “no frost” appliances. In practice, ice build-up will somewhat increase the consumption of “conventional” appliances). | |||
(4) For these appliances, the values of M and N shall be determined by the temperature and star rating of the compartment with the lowest temperature, in accordance with Table 6. | |||
1. Larder fridge | — | 0.233 | 245 |
2. Refrigerator/chiller | 0.75(1) | 0.233 | 245 |
