The purpose of this study was to determine an answer to the question: What are the effects of washer rinse temperature, final washer spin time, or dryer setting on the energy consumption of a household electric clothes dryer? The data were collected in July and August, 1981, using a Maytag washer and dryer. The preconditioned load used was a variation of the Association of Home Appliance Manufacturers' standard eight pound load with fiber content of cotton and polyester. Eight combinations of the independent variables, rinse temperature, spin time, and dryer setting, were replicated five times. Room temperature, relative humidity, and barometric pressure were monitored. Statistical procedures utilized in data analysis included Pearson product-moment correlation coefficients, means, standard deviations, ranges and analysis of variance. The combination requiring the most energy, 3.403 kwh, was cold rinse, short spin time, and extra dry higher setting, and the combination requiring the least energy, 2.588 kwh, was warm rinse, long spin time, and normal dryer setting. However, it was calculated that it required 2.3 kwh to heat the warm water used in rinsing. Therefore, it is recommended that consumers can save the most energy using a combination of cold rinse, long spin time, and normal dryer setting. / Master of Science
