An Energy-Efficient, Ventless Tumbler-Dryer Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-162 Topic Title: An Energy-Efficient, Ventless Tumbler-Dryer Proposal No.: N102-162-0785 Firm: Creare Inc. P.O.

This eliminates the need for very long exhaust ductwork and reduces fire hazards. We propose to develop a reliable, compact, tumble dryer that employs an innovative water separation process that is energy-efficient and does not require an exhaust vent. The water removed in this process is in the liquid phase and thus can be easily drained away, eliminating the need for an air vent. The proposed dryer uses less than half the energy consumed by a conventional dryer. In Phase I, we will prove feasibility by demonstrating the efficient operation of the water separation system, obtaining data to show its water removal rate and power consumption, and designing a ventless dryer prototype. In Phase II, we will build, demonstrate, and deliver a complete prototype ventless dryer to the Navy. Benefits: The technology developed in this project will eliminate the need for exhaust ductwork and fans on Navy ships that occupy precious space, as well as fire hazards associated with lint buildup in the exhaust ducts. Furthermore, the ventless dryer will substantially reduce energy consumption. Energy-efficient dryers will be very attractive for other commercial and residential laundry facilities. This drying technology can also be applied to many industrial processes, such as textile and paper drying. Return
