Symbols, Terms and Units
| Symbol | Description | Unit |
|---|---|---|
e | specific electricity consumption | kWh/100kg |
E | annual electricity consumption | kWh/a |
ΔEeco | cumulative electricity savings | kWh |
Ns | Standard effective duration | a |
P | Ice production | kg/24h |
f | Factor | 24h/a |
nw | Usage intensity | kg/a |
Calculation Formulas
Creditable Electricity Savings
ΔEeco = (Eold - Enew) × feco × Ns
The creditable electricity savings result from the difference between the current and new annual electricity consumption, multiplied by the reduction factor (0.75) and the standard effective duration (10 years).
Annual Electricity Consumption
Ex,i = (ex,i / 100) × nw = (ex,i / 100) × P × f
The annual electricity consumption is calculated from the product of the specific electricity consumption, the ice production and the usage factor.
