Thermoacoustic refrigeration is one of the best alternatives to conventional refrigeration systems due to the use of inert gases such as helium or air. On the contrary, conventional refrigeration systems use refrigerants (CFC) that are harmful to the environment and humans due to global warming and ozone layer depletion issues. It is possible to classify thermoacoustic technology as a clean, renewable technology with a bright future due to its many advantages. Thermoacoustic refrigerators' main function is to utilize sound waves to create a cooling effect. In the present study, the focus is on the design of a standing-wave thermoacoustic refrigerator driven by an ordinary loudspeaker using the simulation program DELTAEC. Additionally, investigating the influence of significant stack and resonator parameters (inertance and compliance) on cooling power and performance coefficient (COP). Hence, the designed thermoacoustic refrigerator performed well in respect of cooling power and coefficient of performance. It has achieved a cooling power of 312 W with a temperature difference of 25 K between the ambient and cold heat exchangers at a COP of 1.9275.

Thermoacoustic refrigeration systems are one of the best alternative solutions for conventional refrigeration systems that are harmful to the environment and humans due to global warming and ozone layer depletion issues. Thermoacoustic technology can be considered a renewable and clean technology with a promising future for its many advantages. A thermoacoustic refrigerator converts acoustic energy to thermal energy (creating a cooling effect). In the present research, the focus is on the design of a standing-wave thermoacoustic refrigerator driven by an ordinary loudspeaker using the numerical simulation program DELTAEC with the concern of building the apparatus at a low cost. In addition, investigating the influence of some crucial parameters on cooling power and thermal/overall performance. Hence, the designed thermoacoustic refrigerator performed well in respect of cooling power and coefficient of performance. It has achieved a cooling power of 134.34 W with a temperature difference between the ambient and cold heat exchangers of 25 K at a COP of 1.956 and the overall efficiency (electrical power converted into cooling power) amounted to 113.43%. The achieved cooling power and COP could be significant when compared to others’ results.
