- W1998972607 abstract "Thermoacoustic refrigerators offer advantages over vapor-compression refrigerators in terms of their inherent mechanical simplicity, lack of chlorofluorocarbon pollutants, and potentially low cost. However, current thermoacoustic refrigerator designs are inhibited by poor efficiency relative to their more conventional counterparts. This paper details attempts to improve the efficiency of a prototype standing-wave thermoacoustic refrigerator through the development of “stiff driver” actuators. Stiff drivers use electronically-driven, lightly-damped structural elements — such as plates or beams — as replacements for traditional drivers. The goal is to reduce the coupling of electromechanical dynamics and acoustical dynamics common to loudspeaker-driven designs while maintaining a cost lower than that of the highly-advanced linear actuators described in some literature. Hofler’s method of using phase-locked loop (PLL) control to track acoustic resonance is altered here in that the output from the PLL is used to modify the geometry of the driver, rather than its driving frequency [1]. Through proper control, the mechanical resonance frequency of the driver is matched to that of the acoustic resonator despite changes in temperature, working fluid, or other factors." @default.
