- Gwreiddiol (a wnaed Fel)
Dyma’r fersiwn wreiddiol (fel y’i gwnaed yn wreiddiol). This item of legislation is currently only available in its original format.
1. Expressions used in this Schedule have the same meaning as in European Standard EN 153 of July 1995 laid down by the European Committee for Standardization.
2. The electricity consumption of an appliance (which may be expressed in kWh per 24 hours) is a function of the category of appliance to which it belongs (e.g. 1-star refrigerator, chest freezer, etc.), its volume and the energy efficiency of its construction (thickness of insulation, compressor efficiency, etc.) and the difference between ambient temperature and the temperature inside the appliance. In setting energy efficiency standards, therefore, allowance must be made for the main endogenous factors which influence energy consumption (i.e., the category of the appliance and its volume). For this reason the maximum allowable electricity consumption of an appliance is defined by a linear equation which is a function of the volume of the appliance, with different equations laid down for each category of appliance.
3. The appliance shall first be allocated to the appropriate category from the following list:
Category | Description |
---|---|
1 | Refrigerator without low temperature compartment (any compartment with a temperature at or below −6°C) |
2 | Refrigerator/chiller with compartment at 5°C and/or 12°C |
3 | Refrigerator with no-star low temperature compartment |
4 | Refrigerator with low temperature compartment (*) |
5 | Refrigerator with low temperature compartment (**) |
6 | Refrigerator with low temperature compartment (***) |
7 | Refrigerator/freezer, with freezer compartment (****) |
8 | Food freezer, upright |
9 | Food freezer, chest |
10 | Refrigerator/freezer with more than two doors, or other appliances not covered above |
4. Because appliances contain different compartments maintained at different temperatures (which will significantly influence electricity consumption), the maximum allowable electricity consumption is defined in practice as a function of the adjusted volume, which is the weighted sum of the volumes of the different compartments.
5. The adjusted volume (Vadj) of a refrigeration appliance shall be defined as:
Vadj = ΣVc × Wc × Fc × Cc
where Tc is the design temperature in each compartment (in °C);
where Vc is the net volume of a given type of compartment in the appliance and Fc is a factor which equals 1.2 for no-frost compartments and 1 for other compartments;
Cc = 1 for refrigeration appliances belonging to the normal (N) and subnormal (SN) climate classes;
CC = Xc for refrigeration appliances belonging to the sub-tropical (ST) climate class;
Cc = Yc for refrigeration appliances belonging to the tropical (T) climate class.
6. The weighting co-efficients Xc and Yc, referred to in paragraph 5, for the different types of compartment are:
Xc | Yc | |
---|---|---|
Cellar compartment | 1.25 | 1.35 |
Fresh food compartment | 1.20 | 1.30 |
0°C compartment | 1.15 | 1.25 |
1-star (*) compartment | 1.12 | 1.20 |
2-star (**) compartment | 1.08 | 1.15 |
3 (***) and 4 (****) star compartments | 1.05 | 1.10 |
Both the adjusted volume and the net volume are expressed in litres.
7. The maximum allowable electricity consumption (Emax, expressed in kWh per 24 hours calculated to two decimal places) for an appliance type with adjusted volume Vadj shall be defined by the following equations for each appliance category:
Category | Description | Emax (kWh/24 h) |
---|---|---|
1 | Refrigerator without low temperature compartment | (0.207 × Vadj + 218)/365 |
2 | Refrigerator/chiller with compartment at 5°C and/or 12°C | (0.207 × Vadj + 218)/365 |
3 | Refrigerator with no-star low temperature compartment | (0.207 × Vadj + 218)/365 |
4 | Refrigerator with low temperature compartment (*) | (0.557 × Vadj + 166)/365 |
5 | Refrigerator with low temperature compartment (**) | (0.402 × Vadj + 219)/365 |
6 | Refrigerator with low temperature compartment (***) | (0.573 × Vadj + 206)/365 |
7 | Refrigerator/freezer, with freezer compartment (****) | (0.697 × Vadj + 272)/365 |
8 | Food freezer, upright | (0.434 × Vadj + 262)/365 |
9 | Food freezer, chest | (0.480 × Vadj + 195)/365 |
For refrigerators/freezers with more than two doors, or other appliances not covered above, the maximum allowable electricity consumption (Emax) shall be determined by the temperature and the star rating of the compartment with the lowest temperature, as follows:
Temperature of the coldest compartment | Category | Emax (kWh/24 hours) |
---|---|---|
> − 6°C | 1/2/3 | (0.207 × Vadj + 218)/365 |
≤ − 6°C (*) | 4 | (0.557 × Vadj + 166)/365 |
≤ − 12°C (**) | 5 | (0.402 × Vadj + 219)/365 |
≤ − 18°C (***) | 6 | (0.573 × Vadj + 206)/365 |
≤ − 18°C (****) | 7 | (0.697 × Vadj + 272)/365 |
