- Abstract
- A conventional clothes dryer and a condenser clothes dryer were tested for their energy performance following the U.S. Department of Energy (DOE) test procedure. The energy required to dry one kilogram (or pound) of moisture and the resulting energy factors were presented. The effect of test room humidity on the energy consumption of the conventional clothes dryer was found to be 0.79% per 10% relative humidity change. Test results indicated that the condenser dryer did not satisfy the requirement of the current DOE energy factor standard. However, when a higher test load than the DOE prescribed test load was used, the dryer exceeded the required standard. Additional tests conducted on the conventional dryer with variable test loads also confirmed the sensitivity of the test load on the energy factor. The study suggests that relating variable test loads directly to the dryer drum volume might alleviate this conflict.
