Division 2 CALCULATION OF THE EQUIVALENT VOLUMEF1

The equivalent volume of a household refrigerating appliance is the sum of the equivalent volumes of all compartments. It is calculated in litres and rounded to the nearest integer as:

where:

• n is the number of compartments

• V_c is the storage volume of the compartment(s)

• T_c is the nominal temperature of the compartment(s) as set out in Table 2

• $\frac{25-T_c}{20}$ is the thermodynamic factor as set in Table 5

• FF_c , CC and BI are volume correction factors as set out in Table 6.

The thermodynamic correction factor $\frac{25-T_c}{20}$ is the temperature difference between the nominal temperature of a compartment T_c (defined in Table 2) and the ambient temperature under standard test conditions at + 25 °C, expressed as a ratio of the same difference for a fresh-food compartment at + 5 °C.

The thermodynamic factors for the compartments described in Annex I, points (i) to (p), are set out in Table 5.
