6. Water consumption for a full load washed and dried; note that con-
denser dryers may use significant amounts of water on the drying
cycle
7. Noise in dB (A) (separately for washing, spinning and drying)
9.2.1.3 Dishwashers
The energy efficiency is calculated according to the number of place settings.
For the most common size of appliance (the 12 place setting machine), the
following classes apply. The unit is expressed in kWh per 12 place settings
(Figure 9.5).
The label also contains:
1. The energy consumption in kWh per cycle
2. The efficiency of the washing cycle, with a class from A to G
3. The efficiency of the drying cycle, with a class from A to G
4. The capacity as a number of place settings
5. The water consumption in litres per cycle
6. Noise in dB(A)
9.2.1.4 Air Conditioners
The directive applies only to units under 12 kW. On every label, you
will find:
1. The model
2. The energy efficiency category from A to G
3. The annual energy consumption (full load at 500 hours per year)
4. The cooling output at full load in kW
5. The energy efficiency ratio in cooling mode at full load
6. The appliance type (cooling only, cooling/heating)
7. The cooling mode (air or water-cooled)
8. The noise rating in dB (where applicable)
