Environmental Engineering Reference
In-Depth Information
For tumble dryers, the energy efficiency scale is calculated using the cotton
drying cycle with a maximum declared load. The energy efficiency index
is in kWh per kilograms of load. Different scales apply for condenser and
vented dryers (Figure 9.3).
The label also contains:
1. The energy consumption per cycle
2. The total cotton capacity
3. Whether the unit is vented or condensing
4. Noise in dB(A)
For combined washer/dryers, the energy efficiency scale is calculated
using the cotton drying cycle with a maximum declared load. The energy
efficiency index is in kWh per kilograms of load. Different scales apply for
condenser and vented dryers (Figure 9.4).
The label also contains:
1. The energy consumption per cycle (washing and drying)
2. The energy consumption per cycle (washing only)
3. Washing performance, with a class from A to G
4. The maximum spin speed
5. The total cotton capacity (washing and drying separately)
