Project: Novel Ultra-Low-Energy Consumption Ultrasonic Clothes Dryer

Oak Ridge National Lab’s Ayyoub Momen demonstrates ultrasonic clothes dryer technology for David Danielson, assistant secretary for Energy Efficiency and Renewable Energy (EERE).

Cold mist is coming out of the saturated fabric sitting on piezoelectric transducer. The fabric dried in less than 14 seconds using direct-contact ultrasonic transducer.

Preliminary measured drying time of fabric sample using ultrasonic cold drying compared to heat drying at 20, 50, 60 and 80°C. A non-optimized, off-the-shelf low-energy-consumption ultrasonic transducer can dry fabric 2 orders of magnitudes faster than thermal drying.
