Abstract: A physical means of dehumidification was used in this study to recover and reuse waste heat emitted from tumble dryers to increase drying efficiency and decrease power consumption. An experiment was conducted; waste heat from a dryer was dehumidified in a heat exchanger, and some heat was reclaimed to preheat external air. After the optimal mixture ratio of external and re-circulated air had been determined, that optimal air mixture was introduced into the dryer through the recirculation air ducts designed in this study.
