Thermoacoustic refrigeration is a perspective technology capable of transporting heat from a low-temperature source to a high-temperature source by utilizing the acoustic power input. It shows the advantages of high reliability, simple construction and operating without hazardous refrigerants. On the other hand, this technology has disadvantage of relative low efficiency in comparison to conventional solutions. Thus, many efforts have been taken in order to improve the performance of the thermoacoustic coolers. The article presents the review of current research. The main attention is focused on the experimental investigations of the optimal selection of the design and the operational parameters of the thermoacoustic refrigerators with the standing wave. The construction and principles of operations of such devices are also described in this paper.
