Defrost Optimization – Job Walk Calculator
Estimate kWh and $ savings from tuning electric defrost per lineup, plus demand savings from staggering overlapping circuits.
Simple field COP (e.g., 1.0–1.5 for LT). Recovery energy = heater kWh ÷ COP.
–Heater kW (lineup)
–Baseline kWh/day
–Proposed kWh/day
–Heater kWh/yr saved
–kWh/yr saved incl. recovery
–Total $/yr (energy)
Formulas: heater kW = cases × amps × volts ÷ 1000; kWh/day = kW × (min ÷ 60) × def/day.
Overlap / Staggering Demand Events
Pick two lineups whose defrosts overlap. Staggering them removes a kW spike.
This row adds demand savings only (heater energy is unchanged).
