Abstract
Energy efficiencies are achieved in a dryer or washer/dryer by selectively varying temperature ranges, time periods, heater power levels, and air flow rates. Efficiency improvements on the order of 16% were obtained over typical constant power, constant temperature, timed drying cycles by varying one or more of these parameters. Efficiencies can also be improved by drawing air from alternative warm sources such as an attic or warm external environment, or by heat recovery from dryer exhaust passages.
