requires good outdoor air quality.
IMEF is the quotient of the capacity of the clothes container, C, divided by the total clothes washer
energy consumption per cycle, with such
energy consumption expressed as the sum of the machine electrical
energy consumption, M, the hot water
energy consumption, E, the
energy required for removal of the remaining moisture in the wash load, D and the combined
low - power mode
energy consumption, L.
