碩士 === 國立臺灣大學 === 機械工程學研究所 === 100 === The study intends to develop a recirculation tumble dryer with the combination of the cross-flow plate heat exchanger. Using the heat exchanger to dehumidify and recover the energy of the exhaust air could enhance the drying efficiency of the tumble dryer. Specific moisture extraction rate (SMER) is an international performance index of the tumble dryer. The study formulates a simple mathematical model to predict the performance of the tumble dryer with different recirculation factor. Besides, the experiments are conducted to verify the theoretical results. The results indicate that as the recirculation factor is 60%, this tumble dryer possess the best performance and whose SMER is 1.099. This case could save 16 percent of the energy consumption compared to the conventional tumble dryer.
