This paper reports on a study of developing a new termination control method for a clothes dryer, using both mathematical modeling and experimental approaches. Drying models in a constant-rate drying period (CRDP) and a falling-rate drying period (FRDP) were developed, based on well-established drying theory and using a "semi-empirical" approach. Drying experiments with regard to drying of cotton fabrics in different drying environments were carried out. A new termination control method using the equilibrium moisture content in ambient environment as a termination point has been investigated. The effectiveness of this new method has been evaluated by both experimental and modelling approaches. The results of the evaluation have demonstrated that the new method is workable and can help achieve energy saving. (c) 2008 Elsevier Ltd. All rights reserved.
