Abstract:

The purpose of the project was to a Small Thermoacoustic Refrigerator SMATAR capable of providing 10W of cooling using 2 bar helium or 2 W using 1 bar air over a 25 K temperature span in a 4 cubic inch package. The device was to use inexpensive transducers and stack and heat exchanger materials and be easy to manufacture. At the end of the grant period, a basic design was complete on paper but the prototype was not yet constructed. The prototype as constructed was capable of providing 0.5W of cooling over a 4 K temperature span using one bar air as a working fluid.
