Title: Experimental investigation on a room-temperature traveling-wave thermoacoustic refrigerator
Abstract: This chapter follows an experimental investigation on a room-temperature traveling-wave thermoacoustic refrigerator. The investigation is involved with the design, construction, and measurement of a prototype. The operation variables such as the working gas, the frequency and the mean pressure are specially considered. Thermoacoustic refrigerators are considered to be an alternative for food refrigeration, air conditioner, and other commercial usages. The design and the performance test of a room-temperature traveling-wave thermoacoustic refrigerator are conducted. The lowest temperature of about -28°C and a cooling power of 108W at 0°C are achieved with helium when driven by a standing wave thermoacoustic engine at a pressure ratio of 1.05. Thermoacoustic refrigeration is achieved through utilization of energy in acoustic wave forms. They have been considered for civil, military, and other industrial applications. This technology could be alternative for conventional technologies, offering the promise of competitive performance combined with an environment friendly system with a few or no moving parts, and no need for lubrication or sliding seals. Gedeon streaming exists in the traveling-wave thermoacoustic refrigerator and it deteriorates the performance of the refrigerator. Suppression of this streaming greatly improves the performance of the refrigerator. The design target is not achieved due to the operation frequency and the amplitude of the pressure.
