Excerpt from Automatic Clothes Dryers: Their Performance and Effect on Certain Fabric Properties Automatic clothes dryers, their various design features, and factors affecting performance were investigated in evaluating home drying methods and their effect on fabric properties. Operating characteristics of the dryers were also determined. In the study, fabrics were dried in automatic gas and electrically heated tumbler dryers, in an electrically heated cabinet dryer, and, for com parison, on indoor racks, and on outdoor lines protected and unprotected from the sun. The automatics included dryers with perforated and nonperforated drum, single and selective thermo stat settings, and dryers designed for operation on 120 and 240-volt circuits.

Volume 1: Characterization of Energy Use in Residential Clothes Dryers. The efficacy and energy efficiency of clothes dryers are studied in this evaluation.

Volume 2: Improved Sensor and Control Designs Many residential clothes dryers on the market today provide automatic cycles that are intended to stop when the clothes are dry, as determined by the final remaining moisture content (RMC). However, testing of automatic termination cycles has shown that many dryers are susceptible to over-drying of loads, leading to excess energy consumption. In particular, tests performed using the DOE Test Procedure in Appendix D2 of 10 CFR 430 subpart B have shown that as much as 62% of the energy used in a cycle may be from over-drying. Volume 1 of this report shows an average of 20% excess energy from over-drying when running automatic cycles with various load compositions and dryer settings. Consequently, improving automatic termination sensors and algorithms has the potential for substantial energy savings in the U.S.
