Worked Example
Verified calculation
Given:
- VSD-equipped pump power consumption = 8.5
- Fixed-speed pump power consumption = 20
- Annual operating hours = 4000
Expected Result:
- Annual energy savings = 46000
Engineering Interpretation:
Under the given input conditions, the calculated result is: Annual energy savings = 46000 kWh.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.
Formula / Method
annual energy savings = (fixed-speed pump power consumption - vsd-equipped pump power consumption) * annual operating hoursFormula family: formula_pump_pump_variable_speed_drive_vsd_energy_savings_estimator
