“…Among these challenges: (i) there is a need for a magnetic material that possesses large MCE; (ii) a strong magnetic field is required, and finally (iii) excellent regeneration and heat transfer behaviors are essential. Several researchers [22][23][24][25][26][27][28][29][30] have investigated the main features of magnetic refrigeration cycles, the perspectives of different models, and magnetic material selection to achieve the highest efficiency. Comparing magnetic refrigeration technology with other environmentally friendly cooling technologies, Table 1 highlights the main attributes of different emerging refrigeration technologies, such as solar adsorption, magnetic refrigeration, and acoustic refrigeration, to identify the primary benefits, obstacles, drawbacks, and performance analyses.…”

Magnetic refrigeration is a fascinating superior choice technology as compared with traditional refrigeration that relies on a unique property of particular materials, known as the magnetocaloric effect (MCE). This paper provides a thorough understanding of different magnetic refrigeration technologies using a variety of models to evaluate the coefficient of performance (COP) and specific cooling capacity outputs. Accordingly, magnetic refrigeration models are divided into four categories: rotating, reciprocating, C-shaped magnetic refrigeration, and active magnetic regenerator. The working principles of these models were described, and their outputs were extracted and compared. Furthermore, the influence of the magnetocaloric effect, the magnetization area, and the thermodynamic processes and cycles on the efficiency of magnetic refrigeration was investigated and discussed to achieve a maximum cooling capacity. The classes of magnetocaloric magnetic materials were summarized from previous studies and their potential magnetic characteristics are emphasized. The essential characteristics of magnetic refrigeration systems are highlighted to determine the significant advantages, difficulties, drawbacks, and feasibility analyses of these systems. Moreover, a cost analysis was provided in order to judge the feasibility of these systems for commercial use.

“…It was mostly Swift (14), at the end of the last century, who started a prolific series of studies dedicated to the design of various types of thermoacoustic engines based on Rott's theory. Since the development of the fundamental theory, many studies have explored practical applications (15)(16)(17) of the thermoacoustic phenomenon with particular attention to the design of engines and refrigerators.…”

Thermoacoustic oscillations have been one of the most exciting discoveries of the physics of fluids in the 19th century. Since its inception, scientists have formulated a comprehensive theoretical explanation of the basic phenomenon which has later found several practical applications to engineering devices.To-date, all studies have concentrated on the thermoacoustics of fluid media where this fascinating mechanism was exclusively believed to exist. Our study shows theoretical and numerical evidence of the existence of thermoacoustic instabilities in solid media. Although the underlying physical mechanism is analogous to its counterpart in fluids, the theoretical framework highlights relevant differences that have important implications on the ability to trigger and sustain the thermoacoustic response. This mechanism could pave the way to the development of highly robust and reliable solid-state thermoacoustic engines and refrigerators.

“…Tijani [40] by utilizing binary gas mixture obtained a low temperature 208 K with TAR analyzed the outcome of various significant factors, like Prandtl number, COP, etc. In pulse tube refrigeration system Jin et al [41] studied thermoacoustic phenomenon, with the help of thermoacoustic prime mover to create an acoustic wave to drive the refrigerator. Thermoacoustic prime mover distinctiveness and effect of working fluid i. e. helium and different percentage of helium-argon mixture, on the TAR was studied, and during experiments achieved cryogenic temperature of 120 K. From [40,41] it shows that the thermoacoustic refrigeration system can achieved low temperature, by utilizing working fluid as a helium with other gas mixture and the binary mixtures according to that various lowest temperature was obtained.…”

To reduce greenhouse gas emissions, internationally research and development is intended to improve the performance of conventional refrigeration system also growth of new-fangled refrigeration technology of potentially much lesser ecological impact. This paper gives brief review of research and development in thermoacoustic refrigeration also the existing situation of thermoacoustic refrigeration system. Thermoacoustic refrigerator is a novel sort of energy conversion equipment which converts acoustic power into heat energy by thermoacoustic effect. Thermoacoustic refrigeration is an emergent refrigeration technology in which there are no moving elements or any environmentally injurious refrigerants during its working. The concept of thermoacoustic refrigeration system is explained, the growth of thermoacoustic refrigeration, various investigations into thermoacoustic refrigeration system, various optimization techniques to improve coefficient of performance, different stacks and resonator tube designs to improve heat transfer rate, various gases, and other parameters like sound generation have been reviewed.
