D  2 or more  E_{1} = 0.296V_{1} + 374 
Remarks:  E_{1} and V_{1} express the following numerical values. 
E_{1}: Standard energy consumption efficiency (unit: kWh/year)  
V_{1}: Adjusted internal volume It shall be a value obtained first by multiplying the rated internal volume of a freezing compartment by either 2.20 for threestar type, 1.87 for twostar type, or 1.54 for onestar type, and then by adding the result to the rated internal volume of storage compartments excluding the freezing compartment, and rounded to the nearest integer.
