Thermoacoustics refrigeration is considered as one of cooling method, which recently developed. This method can be applied for cooling of foods in particular vegetables. The important components in thermoacoustics refrigeration are: resonator tube, Stack, acoustics driver and working fluid. The advantages of thermoacousic refrigeration include the use of relatively simple components, consequent energy saving, and most importantly thing is environmentally friendly. Recent researches has highlighted the necessity to develop resonator tube and stack concerning shape, design, size and basic material which is used to produce resonator tube and stack. This paper comprehensively reviews the current state of technology to develop shape, design, size, and basic material in the development of thermoacoustics refrigeration. It is concluded that the use of bamboo as basic material can be applied with continuing research of its application may lead to the use of thermoacoustic refrigeration for food and vegetables.

“…In the last two decades, the thermoacoustic technology has drawn the attention of many research groups looking for a different way to obtain cooling [19]. This attention resulted in the development of several refrigerators, from prototypes to industrial applications [20,21]. The fundamental advantages related to this technology are: simplicity, compactness and reliability, absence of moving parts (i.e.…”

In the last years, the thermoacoustic phenomena had risen the scientific community interest due to its implications in thermodynamics, heat transfer and acoustic matters, that make possible the conversion between sound and heat. This work aimed at exploring the Russell-Weibull refrigerator, analyzing the behavior of the different parts to achieve a good level of thermal separation, together with the capability of working standalone. Special attention was paid to all those parts that need to be designed properly with explanation of the physics that ruled them, such as the sound generator, the woofer box, the stack and the tube insulation. During the second part of the work, the results obtained are discussed, consistently showing that, if some expedients are adopted, this simple refrigerator can achieve a temperature difference of 24°C. The design choices concerning materials and geometries had great influence on the device behavior.
