# The Energy Efficiency (Refrigerators and Freezers) Regulations 1997, Paragraph 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
