Thermoacoustic refrigerator for space applications
The Journal of the Acoustical Society of America, 1989Long-lived, space-based cryocoolers with low vibration levels are necessary in a variety of applications, including the cooling of infrared sensors and high Tc superconductors. A thermoacoustic refrigerator designed to function autonomously in a Space Shuttle Get Away Special (GAS) canister will be described that has no sliding seals and oldy 15 gm of ...

Thermoacoustic life sciences refrigerator
The Journal of the Acoustical Society of America, 1993This thermoacoustic refrigerator is being built to preserve biological samples (blood, urine, etc.) during Space Shuttle operations. It employs two high-power electrodynamic drivers capable of generating 60 W of acoustic power each, two ‘‘stacks,’’ and four internal heat exchangers in order to produce 700 BTU/h (205 W) of cooling in the refrigerator ...

Thermoacoustic–Stirling model refrigerator
The Journal of the Acoustical Society of America, 2001The design and performance of a model refrigerator that uses a stainless-steel woven regenerator (4.1 cm diameter, 5.0 mm thick) and an unconventional Helmholtz resonator to provide proper phasing for the regenerator are described. Cooling is produced in air at atmospheric pressure with sound pressures in excess of 6 kPa in a transparent 60 cm long ...

Numerical optimization of a novel thermoacoustically driven thermoacoustic refrigerator
The Journal of the Acoustical Society of America, 1997Previous modeling work on a novel heat-driven refrigerator has generated overall COP numbers in the range of 0.45 using pure helium gas. The modeled conditions are for commercial or air-conditioning cooling temperatures, with a hot drive temperature of 400 °C.

Streaming in thermoacoustic engines and refrigerators
AIP Conference Proceedings, 2000The efficiency of thermoacoustic engines and refrigerators is now approaching 40% of the ideal efficiency allowed by the laws of thermodynamics. To achieve such high efficiency requires understanding and control of streaming. Sometimes, thermoacoustic phenomena cause unwanted streaming-driven convection of heat, which we strive to eliminate; in other ...
