Calculation method
- batch heat = product mass × product enthalpy removal × target-temperature factor
- freezing duty = batch heat ÷ cycle seconds
- plant duty = freezing duty × 1.20 fan, defrost and design allowance
- annual electrical energy = plant duty ÷ COP × cycle hours × operating days
- CAPEX band = plant duty × selected system USD/kW factor × low/high range
Il lotto può essere inserito in tonnellate o libbre; la potenza frigorifera è visualizzata in kW, TR e BTU/h. I calcoli restano nelle unità SI di riferimento.
