MELS for Commercial Storage Refrigerators

Energy Efficiency Index (EEI):

1-tick: 80 ≤ EEI ≤ 95 

2-tick: 60 ≤ EEI < 80 

3-tick: 40 ≤ EEI < 60 

4-tick: 20 ≤ EEI < 40 

5-tick: EEI < 20 

Energy Efficiency Index (EEI) = (AEC/SAEC) × 100
where:

AEC = annual energy consumption of the commercial storage refrigerator in kWh/year.

SAEC = standard annual energy consumption of the commercial storage refrigerator in kWh/year.

SAEC = A × Vn + B
where —

1. Vn is net volume, which is the sum of net volumes of all compartments of the refrigerator, expressed in litres; 

2. If the refrigerator is vertical chilled type refrigerator — A is 1.643 and B is 609;

3. If the refrigerator is a vertical frozen type refrigerator — A is 4.928 and B is 1472;

4. If the refrigerator is a counter chilled type refrigerator — A is 2.555 and B is 1790; and

5. if the refrigerator is a counter frozen type refrigerator — A is 5.840 and B is 2380;
