  • The characteristics of a condenser dryer and a vented dryer that are common types of domestic clothes dryers for home use are predicted and compared in an effort to improve the efficiency and to overcome economical and environmental problems due to its inefficient power consumption. In the present study, a drying system is simplified by assuming the mechanism is composed of several elements such as heater and drum and mathematical models using the mass and energy conservation of moisture and air through each element are defined. Based on this mathematical model, the computational tool is developed to predict temperature, humidity and enthalpy of moisture and air in a drum and remained moisture contents (RMC) in drying materials. The computational results are verified by comparing with experimental results from existing studies. In addition, the efficiency of a dryer is calculated using these predicted results for a given condition and the drying characteristics of a condenser dryer and a vented dryer are compared and analyzed.

  • In a clothes dryer, various thermo-fluid flow phenomena occur such as the heat and mass transfer in the process of removing moisture from clothes, the flow field generated by the fan, and the various flow characteristics from the complex flow paths. The study and understanding of such phenomena is an important factor in increasing the performance of dryers. In this study, as part of a dryer research, the flow field inside a vented dryer was measured using PIV, which the result will be used as the basic material in analyzing the various flow phenomena.
