Environmental Engineering Reference
In-Depth Information
The label also contains:
1. The annual energy consumption in kWh per year
2. The capacity of fresh foods in litres for refrigerators and combined
appliances
3. The capacity of frozen foods in litres for freezers and combined
appliances
4. The noise in dB(A)
For cold appliance models (and this product alone) that are more eco-
nomical than those of category A, categories A+ and A++ have been
assigned.
9.2.1.2 Washing Machines and Tumble Dryers
For washing machines, the energy efficiency scale is calculated using a cotton
cycle at 60°C with a maximum declared load. This load is typically 6 kg.
The energy efficiency index is in kWh per kilograms of washing (Figure 9.2).
The energy label also contains information on
1. Total consumption per cycle
2. Washing performance, with a class from A to G
3. Spin drying performance, with a class from A to G
4. Maximum spin speed
5. The total cotton capacity in kg
6. Water consumption per cycle in litres
7. Noise in the washing and spinning cycles in dB(A)
