SCHEDULE 4 Measurement methods and calculations for refrigerating appliances with a direct sales function

1.—(1) Sub-paragraphs (2) to (5) apply for the purposes of the measurements and calculations referred to in paragraph 2.

(2) The ambient conditions must correspond to—

(a) for ice-cream freezers and gelato-scooping cabinets, Set 2 in Table 5;

(b) for all other products, Set 1 in Table 5.

(3) Where a compartment can be set to different temperatures, it must be tested at the lowest operating temperature.

(4) Refrigerated vending machines with compartments with variable volumes must be tested with the net volume of the compartment with the highest operating temperature adjusted to its minimum net volume.

(5) For beverage coolers, the specified cooling speed must be according to the half reload recovery time.

Ambient conditions

	Dry bulb temperature, °C	Relative humidity, per cent	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

2.—(1) The EEI is determined as follows.

(2) For all refrigerating appliances with a direct sales function, the EEI, expressed in per cent 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.

(3) For the purposes of sub-paragraph (2) the AE, expressed in kWh/a and rounded to two decimal places, is calculated as follows—

AE = 365 × E_daily;

where E_daily 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.

(4) For the purposes of sub-paragraph (2) the SAE, expressed in kWh/a and rounded to two decimal places, is calculated as follows—

(a) for refrigerating appliances with a direct sales function where all compartments have the same temperature class, and for refrigerated vending machines, the SAE is calculated as—

SAE = 365 × P × (M + N × Y) × C;

(b) for all other refrigerating appliances with a direct sales function, the SAE is calculated as—

(5) For the purposes of sub-paragraph (4)—

(a) c is the index number for a compartment type ranging from 1 to n, with n being the total number of compartment types;

(b) the values of M and N are as set out in Table 6;

(c) the values of C (the temperature coefficient) are set out in Table 7; for any appliance not listed in Table 7, the value of C is 1;

(d) coefficient Y is calculated as follows—

(i) for beverage coolers, Y_c is the equivalent volume of the compartments of the beverage cooler with target temperature Tc, (Veq_c), calculated as follows—

• Y_c = Veq_c = GrossVolume_c × ((25 - Tc)/20) × CC;

• where—

• Tc is the average compartment temperature and CC is the climate class factor;

• the values for Tc are as set out in Table 8;

• the values for CC are as set out in Table 9;

(ii) for ice-cream freezers, Y_c is the equivalent volume of the compartments of the ice-cream freezer with target temperature Tc, (Veq_c), calculated as follows—

• Y_c = Veq_c = NetVolume_c × ((12 - Tc)/30) × CC; where—

• Tc is the average compartment temperature and CC is the climate class factor;

• the values for Tc are as set out in Table 10;

• the values for CC are as set out in Table 11;

(iii) 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;

(iv) for all other refrigerating appliances with direct sales function, Y_c 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;

(e) the values of P are set out in Table 12.
