For pneumatic systems working with vacuum (negative pressure) the standard power values [W] as shown in Table 8 shall be used.
Table 8
Mechanical power demand of pneumatic systems (vacuum pressure)
| Long Haul | Regional Delivery | Urban Delivery | Municipal Utility | Construction | |
|---|---|---|---|---|---|
| Pmean | Pmean | Pmean | Pmean | Pmean | |
| [W] | [W] | [W] | [W] | [W] | |
| Vacuum pump | 190 | 160 | 130 | 130 | 130 |
Fuel saving technologies can be considered by subtracting the corresponding power demand from the power demand of the baseline compressor.
The following combinations of technologies are not considered:
- (a)
ESS and clutches
- (b)
Visco clutch and mechanical clutch
In case of a two-stage compressor, the displacement of the first stage shall be used to describe the size of the air compressor system
