Determination of the AE

This section has no associated Explanatory Memorandum

3.—(1) For all refrigerating appliances other than low noise appliances, the energy consumption must be determined as follows.

(2) Testing must be carried out at ambient temperatures of 16 °C and 32 °C.

(3) The average air temperatures in each compartment must be equal to or below the target temperatures specified in Table 17 for each compartment type claimed by the manufacturer, the importer or authorised representative. Values above and below target temperatures may be used to estimate the energy consumption at the target temperature for each relevant compartment by interpolation, as appropriate.

(4) The main components of energy consumption to be determined are—

(a)a set of steady state power consumption values (Pss), expressed in Watts and rounded to one decimal place, each at a specific ambient temperature and at a set of compartment temperatures, which are not necessarily the target temperatures;

(b)the representative incremental defrost and recovery energy consumption (ΔΕd-f), expressed in watt-hours (Wh) and rounded to one decimal place, for products with one or more auto-defrost system (each with its own defrost control cycle) measured at an ambient temperature of 16 °C (ΔΕd-f16) and 32 °C (ΔΕd-f32);

(c)defrost interval (td-f), expressed in hours (h) and rounded to three decimal places, for products with one or more defrost systems (each with its own defrost control cycle) measured at an ambient temperature of 16 °C (td-f16 ) and 32 °C (td-f32 ); td-f must be determined for each system under a certain range of conditions;

(d)for each test performed the Pss and ΔΕd-f are added together to form a daily energy consumption at a certain ambient temperature (ET) as follows—

  • ET = 0.001 × 24 × (Pss + ΔΕd-f /td-f ),

expressed in kilowatt-hours per day (kWh/24 h), specific to the settings applied;

(e)Eaux , expressed in kilowatt-hours per year (kWh/a) and rounded to three decimal places.

(5) Each of the parameters in sub-paragraph (4) must be determined through tests.

(6) For the purposes of sub-paragraph (5)—

(a)measurement data must be averaged over a test period which is taken after the appliance has been in operation for a certain time;

(b)to improve the efficiency and accuracy of testing, the length of the test period is not fixed; it must be such that the appliance is in steady state condition during this test period;

(c)the steady state condition is validated by examining all data within this test period against a set of stability criteria determined in accordance with regulation 31.

(7) AE, expressed in kWh/a, must be rounded to two decimal places and calculated as follows—

  • AE = 365 × Edaily/L+ Eaux

Where—

(a)the load factor L is—

(i)0.9 for refrigerating appliances with only frozen compartments; and

(ii)1.0 for all other appliances;

(b)Edaily is rounded to three decimal places expressed in kWh/24 h, and calculated from ET at an ambient temperature of 16 °C (E16) and at an ambient temperature of 32 °C (E32 ) as follows—

  • Edaily = 0.5 × (E16 + E32)

(8) For the purposes of sub-paragraph (7) E16 and E32 are derived by interpolation of the energy test at the target temperatures set out in Table 17.

(9) For low noise refrigerating appliances, the energy consumption is determined in accordance with the preceding provisions of this paragraph except—

(a)testing must be carried out at an ambient temperature of 25 °C;

(b)Edaily, expressed in kWh/24 h and rounded to three decimal places for the calculation of the AE is E25,

where E25 is ET at an ambient temperature of 25 °C and derived by interpolation of the energy tests at the target temperatures listed in Table 17.

Impact Assessments

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:

  • Why the government is proposing to intervene;
  • The main options the government is considering, and which one is preferred;
  • How and to what extent new policies may impact on them; and,
  • The estimated costs and benefits of proposed measures.
