Division 2 Determination of the EEI:

For all refrigerating appliances with a direct sales function, the EEI, expressed in % 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.

The AE, expressed in kWh/a and rounded to two decimal places, is calculated as follows:

AE = 365 × E_daily ;

with:

• 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.

The SAE is expressed in kWh/a and rounded to two decimal places. For refrigerating appliances with a direct sales function with all compartments having the same temperature class and for refrigerated vending machines, the SAE is calculated as follows:

SAE = 365 × P × (M + N × Y) × C;

For refrigerating appliances with a direct sales function with more than one compartment having different temperature classes, with the exception of refrigerated vending machines, the SAE is calculated as follows:

$\mathrm{SAE}=365\times P\times \sum _{\mathrm{c=1}}^n\left(M+N\times Y_c\right)\times C_c$ ;

where:

1. (1)

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