The machine energy includes the energy consumed by all the mechanical and electrical processes necessary to dry a load of laundry (e.g. drum rotation, timers etc.). Equation 16 is used to calculate the machine energy.
x 52 Equation
16where LE = load energy (kWh) loads 52 = weeks/year Machine energy for the average new clothes dryer has not changed significantly over time, so is assumed to be 0.23 kWh/load for the purposes of this model (PG&E 1995). |
